P, K, and M Energy Notes

Potential Energy Kinetic Energy

Mechanical Energy Notes

There are three major types of energy.

•Potential energy

•Kinetic energy

•Mechanical energy

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.

Potential Energy

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

Usually an object has potential energy because of where it is or

because of its condition.

A B C D

MOST potential energy

LEAST potential energy

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

Kinetic Energy

When the ball is MOVING, it is using energy.

Kinetic Energy

When you are moving, you are using energy.

Kinetic Energy

When fish are moving, they are using energy.

Are these fish using kinetic energy?

Why not?

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

Mechanical Energy

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