MS PD:1 One of Newton's laws is that an object in motion tends to stay in motion, unless another force is acted upon it. With our rollercoaster, the rollercoaster gravity was pulling down on the moving cart, stopping it. Potential energy was present during the time the rollercoaster was on the starting hill, and kinetic energy was present while the cart was moving along the track and down the hill.

DeleteI agree with mark because when the cart was at the top of the hill. that was when it had potential energy holding it in its place. until we pushed it and then thats when kinetic energy starting pushing it down the hill and along the tracks.
DeleteSC,P:3- I agree with you because when the car went down the hill it went fast which is kinetic energy and had potential energy when it wasnt moving, that is why I 100% agree with you.
DeleteDN:P8 I agree with mark because potential and kinetic energy were present when the roller coaster was in action.
DeleteVA:P8 I agree another example of Newton's first law is when the roller coaster stopped at the end. Whatever stopped the cart was the unbalanced force that acted against it.

DeleteMS PD1 I agree with you because when I was working on my roller coaster its gravity did make it slow down and stop as well as I like and under stand what you said about potential and kinetic energy.
DeleteCS PD:1 I think that the law that makes most sense to the roller coaster lab is the first law of motion. I think this because the first law of motion states that " Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it." and with that it makes most sense seeing as the roller coaster when we put the car on it kept going until it ended or when we removed a part, also potential energy was high when we were at the top nut when we went down and tried to go up another it wasn't as strong and kinetic energy was strong when the cart was going down the slop instead of going up.
DeleteAC:P7 I agree with you but but a few more details on the rolle r coaster and how the law corresponded with the roller coaster.
DeleteCS P1:I think that scientific names are important because it is a way that scientist understand where other scientists are trying coming from as well as it makes it easier for scientist to know which animal or plant life they are talking about. One scientific name in class that we talked about was the EPITHELIUM also know as the brain tissue of an animal.
DeleteMS P1 I like how you said that its universal because you are right and every scientist should know what your talking about.Like I don't think you would tell other scientist about your topic with the common name instead you would use the scientific name.

ReplyDeleteTR P7:
ReplyDeletean object in motion tends to stay in motion, and a object that is not in motion tends to stay like that unless some type of force is put on it. when we did the roller-coaster kinetic energy was applied when the cart was going down the hill and rolling on the tracks. potential energy was applied when the cart was on the starting of the hill.
I agree with you 100% and liked how you explained how kinetic and potential energy was used during the rollar coaster experiment.
DeleteI agree with you, if the object isn't in motion I believe that a type of force is acted upon.
DeleteI agree with Toni that the potential energy was applied when the cart was on the starting of the hill.
DeleteI agree with you because the Potential Energy was at the top of the hill.
DeleteIG period:7, Thinking back to our roller coaster build Newton's first law which is "Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it" applies because of the force in which we applied to make the cart move and if we did not move the cart, it would stay in the state of motion of being still before moved. Potential and kinetic energy vary as a cart is moving along a roller coaster's path because Potential energy means stored energy and kinetic energy is the ability to move. Therefore the potential and kinetic energy vary as a cart moves through a roller coaster's path because the cart is using it's stored energy and kinetic energy.
ReplyDeleteZC P3: Isabel your response is very good and I agree with all of it. The only thing I would add is that the car wold have more potential energy at the top of the roller coaster.
DeleteI over all agree with Mark but, maybe you should have restated the question to make the answer a bit more understandable.
ReplyDeleteLO:P4
ReplyDeleteAn object in motion stays in motion until it has come to a speed where it is not good enough for the moving object to proceed any farther or has come to a complete stop. When we did the roller coaster experiment, kinetic energy was impacted when the cart was moving down hill. Potential energy was impacted when the cart was moving up hill.
IR:P8 I agree that the kinetic energy impacted when the car was moving downhill because it picked up more speed.
Deletei agree that the object has to have speed to keep going
DeleteAN Pd4 A object in motion stays in motion unless there is some kind of force being applied. When we did the roller coaster, when the cart was going up potential energy was happening also when it was going down kinetic energy was happening.
ReplyDeletePC P.4 I agree with anthony that potential energy was going on when the cart was going up
DeleteThe things stated are true. Another thing you could've said was that there was another force making the cart slow down.
DeleteIR:P8 An object in motion stays in motion unless another force acts on it. When the roller coaster was going up, it had potential energy, and when it rolled down it had kinetic energy.
ReplyDeleteI agree with you,but, you could of said that this is newtons first law. But otherwise good job.
DeletePC P.4 newtons laws do apply to are roller coaster build. Potential energy is a build up of kinetic energy
ReplyDeleteGood, but you should have told how Newton's laws apply to the roller coaster.
Deletean object in motion stays the way is is unless force hits it. When we did the roller coaster the potential energy was it going up and the kinetic energy was it going down.
ReplyDeleteNG P7: I agree. When we pushed the cart to make it move on the track that was an example of Newton's 1st Law.
DeleteI think that newtons law of a object in motion stays in motion relates to this.When the roller coaster when it is at the top of the hill,when it starts to go down the force and speed its going keeps it going
ReplyDeleteThis comment has been removed by the author.
Deletepotential energy is when the roller coaster is at the top of the hill.kinetic energy is then the roller coaster is moving down the hill
DeleteZC P3: One of newtons laws is used in roller coaster physics is the 1st one an object will stay in motion or not be in motion until another force acts upon it. Like our Kinex roller coaster. The car didn't start moving until we gave it a little push.
ReplyDeletePotential energy and kinetic energy vary on a roller coaster depending on how high it is on the hill and how fast the launch of it is.
I totally agree, and the Kinex Roller Coaster is a grate example.
DeleteI agree with your explanation and also like how detailed you are with your answer.
DeleteNG P7: One of Newton's Laws that can be applied to our roller coaster build is Newton's 1st Law. Newton's 1st Law is "An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force". This would apply because in our roller coaster, or any roller coaster, the cart didn't stop until it hit the stoppers at the end that forced it to stop. Potential and Kinetic Energy varies as a cart moves along a roller coaster's path because when the cart goes up a hill, it's building potential energy that will be released at kinetic energy when it goes down the hill.
ReplyDeleteRZ:P3 i agree that the object stays in motion until it is acted upon just how the marble didn't stop until it rolled off the end of the roller coaster track.
DeleteSG P:3- I agree with your explanation and like the way you expanded on the answer
DeleteGreat explanation of how potential and kinetic energy change as a cart travels along the track. Mrs. Zazzali :)
DeleteES:P1 One of Newton's laws was an object in motion, stays in motion unless acted upon another force. With the roller coaster, gravity pulled the cart down. At the top of the hill, Potential Energy was there. At the bottom of the hill, Kinetic Energy was there
ReplyDeleteKR:P8
DeleteWould the Kinetic Energy be at the bottom or in the action of the rollercoaster going down the tracks?
RZ:P3 Newtons laws can be applied because one of his laws is an object stays in motion until something stops it.the marble stayed in motion until it hit the end of the track. it was pulled down by gravity. while a roller coaster cart is going up a hill it builds up potential energy and when it speeds down the hill it releases out the kinetic energy.
ReplyDeleteAS:P7: I agree and i like the way you described everything in detail
DeleteNewtons Laws can be applied because one of Newtons laws was an object that is in motion stays in motion, unless it stopped by an in adamant object. Just like when we had to build those little cars from the k'nex pieces and when we tested it with the lines of tape on the floor.
ReplyDeleteAT-P3:I agree with your response very much and I like how you connected it to other experiments we did.
DeleteAT:P3- One of newtons laws was that an object stays in motion unless acted upon a greater force. For example, the marble would roll until it came across a wall to stop it. If there is no wall, the marble would still be moving.
ReplyDeleteWhen the roller coaster is travling upwards it has potential energy and when it goes down it has kinetic energy. So as the coaster moves up and down the energy changes.
SG P:3- Newtons first law is an object in motion stays in motion and an object at rest stays at rest until acted upon by a force. An example of this law is a ball rolling will never stop until a force acts upon it and a ball at rest will never move unless acted upon by a force.
ReplyDeleteA rollercoaster car that is traveling upwards has potential energy and when i goes down it has kinetic energy.
JJ P:3 I agree because if something isn't acted upon, such as being pushed or pulled, an object can't and won't be able to move with just potential energy being there. Kinetic and potential energy work together when an object is in motion, sort of in harmony.
DeleteLT P3: I agree with your whole answer and another example would be that when you would have to push the roller coaster in order to get it moving.
DeleteKR:P3
ReplyDeleteOne of newtons laws is "For each action there is an equal and opposite reaction." This law would be applied when the roller coaster would goo up a hill, it would have the same amount of force to go down the hill. This would also be an example of kinetic and potential energy. It would have kinetic energy going down the tracks, and potential energy at the top of the hills.
I agree with Kim. I especially think that when she said kinetic energy was shown when the car was moving down the hills was correct.
DeleteIR: P8 I agree with you. Another way Newton's third law is applied is how the tires of the roller coaster push against the track which has the track pushing back on the tire. This allows the roller coaster to move, because both objects push against each other in opposite directions.
DeleteKG, P1
DeleteI agree with you 100%. I especially like when you explained how kinetic and potential energy.
AT/P7
ReplyDeleteNewton's Laws can apply to the roller coaster build because one of the laws said that an object in motion will stay in motion unless acted upon by another force. Same thing goes for if an object is sitting still. For example, we had to push the car to make it move down the track. Potential energy was applied when the car was sitting still at the top of the track. There was kinetic energy when the car was going down the hills.
I agree with Ava because her examples were explained clearly. I understood what she was saying.
DeleteAT P7: I agree with Ava that the kinetic energy was when the cart went down the hills and the potential energy was when the cart was at the to of the track and hills.
DeleteEL P3: I agree with Ava's statement because to make a car move along the track, it had to be pushed. This is where Newton's law comes in as Ava explained.
DeleteDF:P4
ReplyDeleteNewton's Laws of motion can apply to the roller coaster build. One of the laws was that an object in motion will stay in motion unless a larger force is acted upon it. The roller coaster did not move until we pushed it, us pushing it would be the larger force. The roller coaster build had both potential and kinetic energy. When the coaster was just sitting there, potential energy was applied. When it was going down the rest of the roller coaster, kinetic energy was being applied.
JG P:7 I agree with dante because when we didnt push it would stay at the top and it would have a larger force
DeleteZC: P7: I also agree with Dante, but I feel he could've added how Potential and Kinetic energy work in a sort of harmony
DeleteAM P:4
ReplyDeleteNewton's First law goes very well with a roller coaster. The fact that you can't start the coaster without something to give it a push. Like the Kinex roller coaster to start you jest have to give it a push.
AR p8: I agree with Alyssandre because without a force acting upon an object, it will not move.
DeleteNewton's third law is applied when the tires of the roller coaster push against the track which has the track pushing back on the tire. This allows the roller coaster to move, because both objects push against each other in opposite directions. The roller coaster had kinetic energy when it was going down the track. It had potential energy right before that when it was waiting at the start of the roller coaster.
ReplyDeleteI agree with you about the roller coaster push on the tracks because the hills gave it more potential energy.
DeleteAR p8: Newton's laws of motion applies to our rollercoaster build because a object in motion stays in motion until a different force is acting upon it, which is on elf Newton's laws. This is similar to the rollercoaster because the car kept going until the hills acted as a force to slow it down.
ReplyDeleteI agree with you because kinetic and potential energy power a roller coaster
DeleteThis comment has been removed by the author.
ReplyDeleteJG:P:7 One of newton law is that a object in motion tends in stay in motion unless another force is acted upon it. With the rollercoaster the gravity was pulling and stopping it . also the rollercoaster only moved when we pushed it. Potential was at the top and kenectic was during.
ReplyDeleteNewton's second law of motion is that the relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. This can apply to the roller coaster build because the mass of the cart can determine how fast the cart goes and what the is force of the cart on the coaster. After we pushed the cart, the force was determined on how fast the cart was going and its weight. There was also kinetic and potential energy involved with the roller coaster. It varied based on the height of the slopes the coaster had, kinetic energy being the fall of the cart on each slope, and potential energy at the short stop of the cart at the top of the slopes. The energies were applied at different times and were an important part of the roller coaster's function. JJ P:3
ReplyDeleteI agree with you because like newton said, a object can move forever unless a force stops it
DeleteWell done Janie! I was waiting for someone to explain Newton's second law. :)
DeleteAT P7: Newtons law of motion that applied to the rollercoaster was an object in motion tends to stay in motion, unless a force is acted upon it. When the cart went down the hill gravity pulled it down and the hills started to slow down the cart. Every time the cart was on top of the hill it was a result of potential energy. Every time our cart went down the hill it was a result of kinetic energy.
ReplyDeleteThis comment has been removed by the author.
ReplyDeleteNewton's first law, "Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it," applies to our roller coaster because the cart didn't speed up until it started sloping down were gravity pulled it. And when the cart was at the top of the slope, it possessed potential energy, while when it was moving down the slope, it resulted in kinetic energy. JR Period:1
ReplyDeleteGreat job describing the difference between potential and kinetic energy!
DeleteZC: P7: Newton's second law of motion said that an object in motion stays in motion, unless a force is acted upon it. When we moved our roller coaster, gravity was pulling down on it, stopping the roller coaster. Potential energy was used when the roller coaster was starting on the hill, and Kinetic energy was used when the cart was moving along the track and down the hill.
ReplyDeleteI agree with you a 100% but, its Newton's first law not the second. :)
DeleteRF P8
In Newton's 2nd Law we can use our formula for force, who remembers that? Mrs. Zazzali :)
DeleteMM:P8: Newton's second law of motion applied to the roller coaster build. The roller coaster also had acceleration while gravity pulled on it when going down the hill. As Newton's law said; a object can move forever unless a force stops it. The roller coasters could move forever if gravity didn't exist and the tracks were infinite. Potential and kinetic energy also play a part. They are what the roller coaster depends on to work. They were in effect at the fall of the cart and at the moment where it stops for a second.
ReplyDeleteI liked how you clearly described potential and kinetic energy. And how you clearly described how Newtons law applied to our roller coaster.
DeleteI liked how you clearly described potential and kinetic energy. And how you clearly described how Newtons law applied to our roller coaster.
DeleteSC,P:3-One of the laws is that an object that is in motion tends to stay in motion unless force is applied to it. Like our roller coaster it didnt start moving in till we gave it a push. Pontenial energy is shown when it is starting at the hill and kinetic energy was shown when the car was going down the hill.

DeleteI agree but I think you could of elaborated more on how a force can act upon the roller coaster. For example the force of gravity stopped the roller coaster from moving most of the time.
DeleteKG, P1
ReplyDeleteOne of Newtons Laws of motion is that an object in motion tends to stay in motion unless acted upon an outside force. In our roller coaster, the car didn't start moving until we pushed it. At the start of the hill, there was potential energy and when the car went down the hill, there was kinetic energy.
Good job, Kat i was just a little confused this is probably what you meant that Potential energy was the energy that was stored when the roller coaster was on the hill kinetic energy was used when it was going down the hill.
DeleteLT P3: One of the laws is an object that is in motions stays in motions unless a force is acted upon it. The roller coaster would only start to move when we moved it. Potential energy was when the roller coaster was going to the hill and kinetic energy was when the roller coaster was going down the hill.
ReplyDeleteAR: P:7 One of newtons laws is that every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. For example our marble did not move until we pushed it down the roller coaster. When the marble was on top of the hill that was called potential energy when the marble was rolling down the hill that was called kinetic energy.
ReplyDeleteI agree with you and the fact that the roller coaster will stay at the same speed,etc. Also I liked how you involved the marble with the roller coaster and how we had to push it to start.
DeleteMC:P7: In one of Newton's Laws, it states that an object at rest will stay at rest and an object in motion will stay in motion until acted upon an unbalanced force. This is related to roller coasters because at the beginning of the ride, the roller coaster is at rest, then when the ride begins, the roller coaster won't stop until it breaks and comes to a halt. Also, at the top of the hill, the roller coaster has potential energy and as it goes down, it picks up more and more kinetic energy.
ReplyDeleteThis comment has been removed by the author.
ReplyDeleteEL P3: Newton's first law states how an object in motion must stay in motion unless acted upon by a larger force. Also, an object at rest will stay at rest until acted upon by a force. This applies to our roller coaster build because the marble did not move through the roller coater until it was acted upon by a force. In this case, we were the force since we were the ones to push the marble. When the marble started off at the top of the hill, potential energy was present. As the marble rolled, kinetic energy happened.
ReplyDeleteIE:7 Thinking back to our roller coasters one of Newtons laws states, "An object in motion tends to stay in motion,unless a force is applied on it. This applies because when we pushed the roller coaster sometimes the force of gravity pulls it down. Potential energy was the energy that was stored when the roller coaster was on the hill kinetic energy was used when it was going down the hill.
ReplyDeleteI agree with Ibrahim.
DeleteRF P8- For Newtons 3rd law "Every action has an opposite reaction" when the roller coaster started, its action was to go down the hill with the force of gravity and Potential Energy. The reaction is when the roller coaster had enough momentum and Kinetic energy to make it up the next hill.
ReplyDeleteNice mention of Newton's third law and I like how you explained the action-reaction. Mrs. Zazzali :)
DeleteMO P7 Once we applied force on the roller coaster cart, its potential energy pulled it downward and then it used its stored up energy to launch itself upward. As we know from Issac Newton, an object in motion tends to stay in motion unless another force acts upon it, which means that the roller coaster could keep going up the tracks until another force would stop it, like at the ending with our finish line.
ReplyDeleteGR:P1 good job Matt but you should of put more detail on saying one of the rules from Issac Newton
DeleteGR:P1 when you apply force on the coaster its potential energy pulls it downward saving up energy to pull it up. I know this because Issac Newton rules are when a non motionless object is not moving, it could move with the help of a motion object.
ReplyDeleteMO P7 I agree but the potential energy isn't what stores the energy to push it up the hill, it's the carts kinetic energy.
DeleteJL: period 7: one of Newton's laws that were in action when we made the roller coaster was law number 1. When we pushed the cart it wouldn't stop until gravity pull the car down stopping it from going forward
ReplyDeleteA.I:Period 8:
ReplyDeleteOne of Newtons laws states, "An object in motion tends to stay in motion,unless a force is applied on it. An example is if a ball was rolling down a hill, it wouldn't stop until a force is applied on it
OM P1 I like that you also added an example of the first law
DeleteThis comment has been removed by the author.
DeleteA.I:Period 8:
ReplyDeletePotential energy was the energy that was stored when the roller coaster was on the hill kinetic energy was used when it was going down the hill.
DN:P8 Newton's first law is that an object in motion tends to stay in motion, unless another force is acted upon it. This law applies to our roller coaster because gravity was pulling the cart down. Potential energy was active when the cart was at the beginning of the roller coaster, and kinetic energy was active when the cart was going up and down the roller coaster.
ReplyDelete(md,p:3) i agree with dylan because i checked my notes and saw that he was completly right.
DeleteVA: P8 One of Newtons laws was that an object in motion stays in motion unless acted on by another force. This is shown with the roller coaster because the car keeps going until a force stops it. Potential energy is shown when the roller coaster is at the top of the hill about to go down, the potential energy will be turned to kinetic energy once it starts going down the hill.
ReplyDeleteZC P8: In Newton's first law it says that an object in motion will stay in motion until acted upon by an equal force. This law relates to roller coasters because without the friction between the brakes and the car tracks, the car would continue rolling. When at the top of a hill on a roller coaster, the car has stored energy called, potential energy. While going down, the potential energy turns into kinetic energy using momentum and gravity to go down the hill.
ReplyDeleteP4, ES Newton's laws could be applied in our roller coaster because our roller coaster would just stay in motion if we didn't put hills on it. Potential energy stores us to be kinetic energy by mass and velocity.
ReplyDeleteI agree with edelmira but she can aslo give more detail.
DeleteNF:P1 Newton's first law would apply to the roller coaster lab because it states that an object in motion stays in motion unless a force is applied to it. When a roller coaster is at the top of the hill it stores up something called potential energy. As the cart moves down the path it loses the potential energy and gains kinetic energy .
ReplyDeleteI agree with Naomi because I forgot to add that a force needs to applied to the coaster in order for it to build up the kinetic energy to go down the first hill
DeleteI agree with Naomi because she is right about the potential energy on the top of the first hill and how it loses more energy as the cart moves along the track.
DeleteNF:P1 I agree with Edelmira, but maybe you should explain more about Newton's law.
ReplyDeleteMC P4 Newton's 2nd law of motion is applied to the roller coaster we made because on the first hill the car builds up kinetic energy going down the first hill being that its mass causes it to accelerate. The kinetic energy it builds up on the first hill is just enough to push the car up the 2nd hill and completing the coaster.
ReplyDeleteA.S period 7 Newtons law is applied cause it all has to do with motion and speed. When the roller coatser was at the top and then gravity pulled it down fastly. The kinetic energy made the roller coater go up and son the roller coaster on to the 2nd hill.
ReplyDeletei agree that gravity also is a big part in making it go faster and move.
DeleteA.V P1:
ReplyDeleteNewtons law is that an object in motion stays in motion stays in motion unless force is applied to it. When a roller coaster is about to go down that is potential energy. The energy that is released when the roller coaster is going down is called kinetic energy.
I agree with you but you should have at least said what newtons law like put newtons first law. Other than that I agree with you. :)
DeleteC.C P:4 Newtons law is that when an object is in motion it shall stay in motion unless force is added to it. When the roller coaster goes up it is potential energy because it did not reach its maximum speed. And entice energy is when the roller coaster would past the high point and reach it maximum speed.
ReplyDeletePotential energy is when it has stored energy, kinetic is the energy when it is in motion.
DeleteOM P1 Newton's first law of motion is an object in motion stays in motion until force is applied. When the roller coaster is at the top of the hill it stores energy called potential energy and when it goes down gravity turns it into potential energy
ReplyDeleteI agree with zach because he gave a full defintion without missing anything.
ReplyDeleteRS Pd.7
ReplyDeleteOne of Newton's laws is an object in motion tends to stay in motion, unless other forces is acted upon it. With the roller coaster, it's gravity was pulling down on the moving car making it stop. Potential energy was involved at the time the roller coaster was at the top and kinetic energy was also while the car was moving down the hill.
I agree with you olivia but maybe next time put more details for the energys.
ReplyDelete(md,p:3) one of newtons laws is newtons first law. a object that is in motion stays in motion unless force has been applied. potential energy is when energy is building up. like in our lab when when the coaster went up the hill. kenetic energy kicks in when the coaster goes down the hill it releases the potential energy.
ReplyDeleteHS P4: One of Newton's laws is that when an object is in motion it would stay in motion unless force is added to it. This is in the roller coaster since the roller coaster keeps going until a force stops it. When a roller coaster goes up its potential energy because it did not get to its most speed. As the roller coaster cart is going down it realeses the potential energy and changes to kinetic energy.
ReplyDeleteI agree with hailey and she had good detail
DeleteCG P1: I agree with hailey because when the roller coaster cart is going down it does release potential energy and changes into kinetic energy. Good job
Deletehv:p.4 one of newtons laws is when an object is in motion it stays in motion unless force is added to it. this happens with a roller coaster because it goes up with potential energy and then once it is in motion it doesn't stop until the force stops it. as the roller coaster starts to drop at a high elevation its potential energy changes into kinetic energy
ReplyDeleteKQ:P.3 I agree with Hailey because she said the potential energy changes into the kinetic energy as it moves.
DeleteThis comment has been removed by the author.
ReplyDeleteCG P1: According to Newton's second law, the relationship between an object's mass (m), its acceleration (a), and the applied force (F) is F=ma. For example, when the roller coaster is going down a steep hill, the force of gravity makes the coaster speed up. When the roller coaster goes up, it's building potential energy. Then when it releases from the top it becomes kinetic energy.
ReplyDeleteYes I agree with Charmaine. I like how Charmaine included the formula.
DeleteCF P1- One of Newton's laws is that an object will stay in motion unless a force acts upon it. This applies to roller coasters in the way that friction between the cart wheels and the track slows the cart down. Potential and Kinetic energy are also acting on the cart. When the cart reaches the top of a hill, it has potential energy because it is still for a moment, right before its energy goes in motion. Kinetic energy is acting on the cart when it is in the act of going down the hill, since the cart's energy is in motion.
ReplyDeleteI agree with charmaine because she said that with a steeper hill, the cart will go faster. The flatter the hill, the slower the speed.
ReplyDeleteI agree with Cooper because he said that friction between the wheels and the cart slows it down. That reminds when you go on a slide and by the end the friction slows you down as you get to the bottom.
DeletePP P7: One of Newton's laws states that an object in motions stays in motion unless another force acts upon it. A roller coaster for example, when it goes up the hill it stores Potential energy. But when the roller coaster goes down the hill Kinetic energy acts on the roller coaster because it's in motion.
ReplyDeleteJD :P4 At the top of the roller coaster hill is potential energy going down a hill is kinetic energy the whole time it is the conservation of energy.all thought kinetic energy can move down hill is that it picks up speed to make kinetic energy. The potential energy is a result of gravity pulling downwards.
ReplyDeleteThis comment has been removed by the author.
DeleteI agree with jordan the the kinetic energy is going down the hill the whole time untill it stops
DeleteJD :P4 i agree with cooper because he said between the wheels and cart slows it down. Then the kinetic energy is acting on a cart when it is in the act of it that it is at a fast speed but slowing down as it goes of kinetic
ReplyDeleteAM :P8 In Newton's first law it says that an object in motion will stay in motion until acted upon by an equal force. This law relates to roller coasters because without the friction between the brakes and the car tracks, the car would continue rolling. When at the top of a hill on a roller coaster, the car has stored energy which is called, potential energy. And when the car is going down, the potential energy turns into kinetic energy using momentum.
ReplyDeleteMB P8: I agree with Alex because he said that potential energy turns into kinetic energy using momentum.
DeleteMB P8 Newton's first law: Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. A roller coaster has potential energy when it is on top of the Peak and kinetic when it is in motion
ReplyDeleteI agree with maguire because he explained when the cart has the most potential energy and when the cart has kinetic energy
DeleteKQ:P.3 The object was in motion then there was a balance in force. The most potential energy will happen at the very top of the hill, the most kinetic energy will happen at the bottom of the first hill.
ReplyDeleteI agree with you that there is a balanced force in motion. H.M p.4
DeleteAA:P.8 Going back to when we did the Rollercoaster experiment Newtons first law was, every object in a state of uniform motio. Tends to remain in that state of motion unless an external force is applied to it. The roller coaster had energy on the top of the hill and push to get kinetic movement
ReplyDeleteSO p.4 Newtons first law is every object in a state of motion tends to remain in that state of motion unless an external force is applied to the object that is in motion. On a rollercoaster The rollercoaster has the most potential energy when it is at the very top of the first drop and it has kinetic energy when it is in motion along the tracks.
ReplyDeleteJY p.4 Newtons first law is applied because when the cart is at the top of the hill the only thing that is pushing it is the band that pulls it to the top. After the cart goes off the top of the rollercoaster the only force that is pushing it is the weight of the cart while the ride goes down. The rollercoasters most potential energy is at the top of the the first hill and when it moves on the tracks is has kinetic energy.
ReplyDeleteAccording to Newtons first law an object stays in motion unless a force is applied on it. When we pushed the cart down the hill it had a lot of kinetic energy and it needs a lot of potential energy to make it up the next hill.
ReplyDeleteThis is Newton's first law of motion "An object in motion stays in motion". When the cart went down the ramp, it had kinetic energy, and when it went up the ramp, it had potential energy.
ReplyDeletesc.04 yes i do agree with your response molly and also when we did the rollercoaster the mass that was in the rollercoaster alter the acceleration which caused the rollercoaster to move at a kinetic energy.
DeleteNewton's first law states that an object in motion stays in motion. When the "coaster" when down the ramp the "cart"had kinetic while when it when up the ramp it had potential.

DeleteOne of Newtons laws states that "An object in motion stays in motion" So for example on the rollercoaster it had potential energy going up and kinetic energy going down and that's what kept it to stay in motion.

DeleteOne of newtons laws is that and object in motion stays in motion. As an example using the roller coaster it had potential energy going up and kinetic energy coming down. And this is what kept it to stay in motion AC:p7
ReplyDeleteOne of Newton's laws is if an object is in motion it will stay in motion until an object at rest acts upon it. for example the roller coaster it started from the top to get the highest speed so it could go over the second bump. MD pd1
ReplyDeletei agree with arianna because the roller coaster did have potencial energy going up an kinetic energy going down
ReplyDeletei agree with arianna because the roller coaster did have potencial energy going up an kinetic energy going down
ReplyDeletenewtons first law says that an object that is in motion will stay in motion unless a force acts upon it to stop the motion, the roller coaster starts from the top which is when it has the biggest amount of potential energy and when it goes down it has kinetic energy
ReplyDeletei agree with morgan because newtons first law has to do with potential and kinetic energy
