A man stands on the top of the hill at point A and then runs down at point B. What kind of energy conversion occurs from point A to point B?
- kinetic to heat
- elastic potential to kinetic
- gravitational potential to kinetic
- kinetic to elastic potential
- kinetic to gravitational potential

The answer is gravitational potential to kinetic energy

Explanation:

On the top of the hill there is height and distance to fall and gravity will have more potential. For instance gravity is represented by 9.81 m/s^2 which means that it will accelerate. And when on top of a hill there is more time to accelerate, and that is it's gravitational potential. Then when going down the hill that potential energy is transformed into kinetic energy (which is defined as a body in motion). Hence, the man from the top of the hill, point A, to moving down the hill, point B, starts with gravitational potential at point A, then that potential is transferred into kinetic energy at point B.
