1. Energy Notes

2. Energy ~ the ability to do work
~ measured in units of Joules
~ Work = change in energy

3. Potential Energy ~ energy stored and held in readiness
Gravitational Potential Energy ~ energy due to an objects elevated position
~ PE = Weight x Height = (mg) x (h)
~ PE = mgh
~ units of joules

4. Other types of Potential Energy:
Elastic or Spring Potential Energy
Chemical Potential Energy

5. Kinetic Energy ~ energy of motion
~ If velocity doubles, KE quadruples
~ Units of Joules

6. Conservation of Energy ~ Energy cannot be created or destroyed; it may be transformed from one form into another, but the total amount of energy never changes
