Answer

Brief Explanations:

The total mechanical energy of the roller - coaster car at each location (sum of kinetic and potential energy) is constant. Kinetic and potential energy values change at different locations, which is in line with the law of conservation of mechanical energy.

Answer:

B. Kinetic and potential energy change, but total energy stays the same.
