1. P, K, and M Energy Notes

2. Potential Energy Kinetic Energy Mechanical Energy Notes

3. There are three major types of energy.
Potential energy
Kinetic energy
Mechanical energy

4. Potential Energy: the energy of something NOT in motion
Potential Energy: the energy of something NOT in motion. This item has the energy stored inside of it. It is not using the energy right now.

5. When the ball is NOT moving, it is storing its energy.
Potential Energy
When the ball is NOT moving, it is storing its energy.

6. Usually an object has potential energy because of where it is or because of its condition.
MOST potential energy
LEAST potential energy
A B C D

7. Kinetic Energy: the energy of moving
Kinetic Energy: the energy of moving. If it is moving, it is using kinetic energy. Types of kinetic energy:
Chemical energy
Electric energy
Light energy
Sound energy
Heat (thermal) energy
Mechanical energy

8. When the ball is MOVING, it is using energy.
Kinetic Energy
When the ball is MOVING, it is using energy.

9. When you are moving, you are using energy.
Kinetic Energy
When you are moving, you are using energy.

10. When fish are moving, they are using energy.
Kinetic Energy
When fish are moving, they are using energy.

11. Are these fish using kinetic energy?
Why not?

12. Which are using kinetic energy and which are using potential energy ?

13. Mechanical Energy
Mechanical Energy: the energy of something in motion and doing work. Something must be accomplished to be considered work.
