Question 11

If you drop a basketball, it will bounce, and then roll, and finally stop.
Why won't a basketball bounce forever?

Accepted Answer

It's energy is transformed into other types of energy.

Answer

The ball weighs too much, and that makes it stop.

Answer

Gravity pulls the ball down more than the ball can bounce.

Answer

It's Potential Energy gets destroyed as it bounces.
