Front

What is kinetic energy?

Back

energy of motion

Front

Where does a ball have the most potential energy?

Back

On the top of a hill.

Front

Collisions can be ____________or ___________.

Back

elastic or inelastic

Front

Which of the following would transfer more energy? Raising ball 1 higher before release or keeping ball 1 in the same place?

Back

Raising ball 1 higher before release.

Front

What is the formula for kinetic energy?

Back

KE = 1/2 mv² (where m is mass and v is velocity)

Front

What happens to kinetic energy when the speed of an object doubles?

Back

It quadruples.

Front

What is the difference between elastic and inelastic collisions?

Back

Elastic collisions conserve kinetic energy; inelastic collisions do not.

Front

What is potential energy?

Back

Energy stored in an object due to its position.

Front

How does height affect potential energy?

Back

Potential energy increases with height.
