If the mechanical energy of a body is conserved,
A) no net work is done on the body.
B) no net work is done by the body.
C) a change in its gravitational potential energy is accompanied by the same change in its kinetic energy.
D) a change in its gravitational potential energy is accompanied by a change in its kinetic energy, equal and opposite in sign.

Question

Quizplus · Accepted Answer

When mechanical energy is conserved, any change in gravitational potential energy is exactly offset by an equal and opposite change in kinetic energy, ensuring the total mechanical energy remains constant.
