How could you increase the gravitational potential energy of an object without changing its mass and gravity?

• Make the object larger

• Lower the object towards the ground

• Raise the object farther off the ground

• Allow the object to roll on the ground

Which object has the most potential energy?

• A ball resting on the ground.

• A ball being thrown at 100 miles per hour.

• A ball on top of a refrigerator.

• A ball resting on the edge of a cliff.

Explain what happens to the potential energy of a rock as it falls off the side of a cliff.

• The kinetic energy decreases as the potential energy increases.
• The kinetic energy decreases as the potential energy decreases.
• The potential energy decreases as the kinetic energy increases.
• The potential energy decreases as the kinetic energy decreases. 

When a roller coaster is at the top of a hill it has

• high potential energy
