• Chemical
• You will see other types or forms of energy in
  books and on the Internet

4
Energy can be divided into two general
categories

• Potential
• Kinetic

5
Potential Energy

• Stored energy
• Energy of position
• The amount of usable energy in a body at rest
• Sometimes called GRAVITATIONAL POTENTIAL ENERGY
