B. potential energy being converted into kinetic energy
C. kinetic energy being converted into potential energy
D. mechanical energy being converted into potential energy
The answer is B. POTENTIAL ENERGY BEING CONVERTED INTO KINETIC ENERGY
Potential energy is greater the higher an object is from the
Earth. Potential energy was converted into kinetic energy as the boulder broke free from
the mountain and began to move.
