Question

A ball is sitting at the top of a ramp. As the ball rolls down the ramp, the potential energy of the ball decreases. What happens to the potential energy as the ball moves?

Answer 1

Answer:

The potential energy of the ball is converted into kinetic energy as the ball moves.

Explanation:

Potential energy depends on height and kinetic energy depends on speed.

As the ball rolls down the ramp, the height of the ball decreases meaning that the potential energy also decreases.

Scientists say that energy cannot disappear, so it means that the decreased potential energy turns to be increased kinetic energy as the ball gains speed.
