A ball is dropped from 3 different heights. Each time the kinetic energy of the ball for when it hits the ground is calculated. The data shows the higher the ball started the more kinetic energy it had. If the height of the drop continued to increase what would happen to the kinetic energy?
What is the kinetic energy would also continue to increase.

When you drop a tennis ball, it hits the floor and bounces back up. But, it does not reach the same height as before and each time bounce is smaller than the previous one. However, you notice the tennis ball is slightly warmer after it finishes bouncing. Explain how the law of conservation of energy is obeyed.
What is During each bounce, some of the kinetic energy of the ball in transferred into thermal energy. As a result, energy is not created or destroyed, but only changes form so that the law of conservation of energy is obeyed.
