4. What Is Energy? Potential Energy Section 1
Gravitational Potential Energy
When you lift an object, you do _________ on it. You use a force that is against the ___________. When you do this, you ___________energy to the object & give the object gravitational potential energy.
Calculating Gravitational Potential Energy
Gravitational potential energy = an object’s weight X its height-
pounds X inches or kilograms X centimeter.
Height Above What? Gravitational potential energy depends on your point of view. So, height is a measure of how far an object has to fall.

5. Tsunamis are a special type of water waves
Tsunamis are a special type of water waves. Waves you see at the beach are usually created when wind transfers energy to the ocean’s surface. However, with tsunamis, the potential energy in tectonic plates or an underwater landslide can be transformed into the kinetic energy of moving tsunami waves.

6. What Is Energy? Mechanical Energy Section 1 What Is Mechanical Energy?
Mechanical energy is the ___________ ___________of motion and position of an object.
Mechanical Energy in a Juggler’s Pin
The mechanical energy of an object remains the same unless it transfers some of its energy to another object.
If the mechanical energy of an object stays the same, the potential or kinetic energy it has can __________or decrease.
