2 Forms of Energy –Kinetic and Potential
Kinetic energy• Kinetic energy is
movement energy• This is energy that is
being used for movement right now.
• KE = mv
Potential energy• Potential energy is
stored energy.• This is energy that could
be used in the future, but isn’t being used right now.
• PE = mgh
Potential and kinetic• Most different types of
energy can be classified as either kinetic energy, potential energy, or both.
The sum of the kinetic and potential energy is called mechanical energy
Potential and kinetic• Potential energy can
turn into kinetic energy, and kinetic energy can turn into potential energy.
• This means that kinetic and potential energy are cyclic.
