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

• The ball weighs too much, and that makes it stop.
• Gravity pulls the ball down more than the ball can bounce.
• It's Potential Energy gets destroyed as it bounces.
• It's energy is transformed into other types of energy.
