Question

To investigate how mechanical energy affects the number of times a ball will bounce back, Maria dropped a ball from three different heights. Which of the following would be a reasonable conclusion from this experiment?

The height from which a ball is dropped does not affect the number of times it bounces.
Increasing the height will give the ball more energy and will increase the number of times it bounces.
Increasing the height will give the ball less energy and will decrease the number of times it bounces.
Decreasing the height will give the ball more energy and will increase the number of times it bounces.

Answer 1

Increasing the height will give the ball more energy and will increase the number of times it bounces.
