How will the total energy change as the car moves from point A to B to C? Assume that none of the energy is lost as friction or heat energy.
A The total energy will increase as the kinetic changes to potential and back again.
B Kinetic energy will change into potential energy and back again, but the total energy will stay the same.
C The total energy will decrease because the potential energy will change into kinetic energy.
D The total energy will decrease since it is losing potential energy at point E.
