Responses
A.Thermal changes to potential, then some potential changes to thermal.
B.Potential changes to kinetic, then some kinetic changes to potential.
C.Kinetic changes to potential, then some potential changes to kinetic.
D.The amount of potential and kinetic energy does not change as the car moves.

The correct statement describing the energy transformation as the roller coaster moves from point A and stops at point B is:
B. Potential changes to kinetic, then some kinetic changes to potential.
As the roller coaster descends from a high point (potential energy) and speeds up (kinetic energy), when it begins to ascend again, some of that kinetic energy converts back into potential energy.
