Which of the following is an example of kinetic energy?

• A stretched rubber band

• A moving car

• A book on a shelf

Potential energy is best described as:

• Energy of motion

• Energy stored due to position or shape

• Energy that is lost when an object stops moving

• Energy that disappears when an object slows down

NGSS.MS-PS3-5

True or False: Potential energy decreases as an object moves downward.

• True

• False

True or False: An object can have both kinetic and potential energy at the same time.
