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
