Question

a ball is dropped from a window and bounces three times. the first bounce is 60 centimeters high. The second bounce is 40 centimeters high. The third bounce is 15 centimeters high. The ball then rolls and comes to a stop. What was happened to the energy of the ball when it has come to stop?

Answer 1

The potential energy of the ball has increased during energy transfer.

We know that potential energy is position relative, and kinetic energy is motion relative. The primary relationship between the two is their ability to transform into each other. In other words, potential energy transforms into kinetic energy, and kinetic energy converts into potential energy, and then back again. It’s a never-ending cycle. So, when the ball came to rest the   potential energy of the ball has increased.
