Lesson 4-Elastic Energy

Front

What is elastic energy?

Back

Energy that an object has because it can bend or stretch.

Front

What is the elastic limit?

Back

The point at which an object stops stretching and starts to tear.

Front

At which point does a bouncing ball have maximum elastic energy?

Back

At point C.

Front

What type of energy conversion occurs at point B of a bouncing ball?

Back

Gravitational to kinetic.

Front

At which point does a bouncing ball have maximum gravitational energy?

Back

At point A.

Front

What is gravitational energy?

Back

Energy an object possesses due to its position in a gravitational field.

Front

What is kinetic energy?

Back

Energy that an object has due to its motion.

Front

What happens to elastic energy when a rubber band is stretched?

Back

It increases as the rubber band is stretched.

Front

What is an example of elastic energy in everyday life?

Back

A stretched spring or a drawn bow.

Front

How does elastic energy convert to kinetic energy in a bouncing ball?

Back

As the ball compresses, elastic energy is stored and then released as kinetic energy when it bounces.
