Explain why a basketball doesn’t bounce the same height each time you drop it.

The basketball do not bounce back to the same height after each drop due to the fact of loss of kinetic energy.

Explanation:

When the basketball or any ball is dropped off from a certain height it falls down under the influence of gravity with the kinetic energy which has been transferred to the ball with hand by dribble.

When the basketball hits the ground with the kinetic energy, it loses some of the energy to the ground and then with the action reaction pair with the ground, is bounced back but with lower energy to a lower height.
