Where does the roller coaster have the least potential energy?
Where does the roller coaster have the least potential energy? Gravitational potential energy is greatest at the highest point of a roller coaster and least at the lowest point.
Where is negative acceleration on a roller coaster?
Once the cars are put into motion (potential is allowed to be converted into kinetic energy), they will not stop again until the brakes are applied at the end of the ride. The cars are slowed (negative acceleration) eventually to a stop, because of unbalanced forces due to friction acting on them.
Where does the roller coaster have the most kinetic energy?
The maximum kinetic energy generated is when the roller coaster is at the bottom of the track. When it begins to go up, the kinetic energy converts to potential energy.
Why is the back of a roller coaster faster?
It is impossible for the back of the train to exceed the speed of the front, because all of the cars are connected. However, the back may feel faster than the front at some points, due to the front pulling it. If the front is already going down a drop, than it is going to whip the back over the crest faster.
Why do you feel heavier at the bottom of a roller coaster?
At the bottom of the loop, gravity and the change in direction of the passenger's inertia from a downward vertical direction to one that is horizontal push the passenger into the seat, causing the passenger to once again feel very heavy.
