3
There are three major types of energy.

• Potential energy
• Kinetic energy
• Mechanical energy

4
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
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.

7
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
Kinetic Energy
When the ball is MOVING, it is using energy.
9
Kinetic Energy
When you are moving, you are using energy.
10
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.
