Conservation of Energy and Momentum

Energy stored because of gravity is called:

• Gravitational Potential Energy

• Kinetic Energy

• Mechanical Advantage

• Chemical Energy

At which point does the ball has the greatest gravitational potential energy (GPE)?

• A

• G

• D

• C

• G

Which would have the LEAST gravitational potential energy (GPE)?

• Allow the object to roll on the ground

How could you increase the object's gravitational potential energy (GPE) without changing its distance from the ground (height) and gravity?

• Decrease the object's mass

• Increase the object's height

• Increase the object's mass

• Decrease the object's height
