Which of the following energy changes occurs as a ball bounces?
potential to chemical
magnetic to kinetic
thermal to mechanical
kinetic to potential

Option (d) is the correct answer.

Explanation:

Kinetic energy is defined as the energy possessed due to the motion of an object.

Whereas potential energy is the energy possessed due to the position of an object.

When a ball bounces then it means the ball has moved or is in motion. Thus, the ball has some kinetic energy. Whereas after certain bounces the ball will finally come to rest at a certain point.

Therefore, at that point the energy possessed by the is due to its position. Thus, ball will have a potential energy.

Hence, we can conclude that kinetic to potential energy changes occurs as a ball bounces.
