How does conservation of energy explain why something that is falling should speed up? O It loses kinetic energy because no work was done on it. O It loses kinetic energy because the Earth gains potential energy. O It gains kinetic energy because it gains potential energy. O It gains kinetic energy because it loses potential energy.
