Understanding Potential Energy

What is the primary characteristic of potential energy?

• Energy that is lost

• Stored energy or energy of position

• Energy that is visible

• Energy in motion

How is gravitational energy related to potential energy?

• It is energy that is always kinetic

• It is energy due to an object's position

• It is energy due to an object's motion

• It is energy that cannot be converted

What is an example of gravitational energy in use?

• A ball at the top of a hill

• A compressed spring

• A moving bicycle

• A burning log

Which of the following is an example of stored mechanical energy?

What happens when a stretched rubber band is released?

• It gains gravitational energy

• It remains stationary

• It converts potential energy to kinetic energy

• It loses all energy
