Potential and Kinetic Energy

• Energy has two different states

• Kinetic Energy is energy is motion. The energy is currently being used to accomplish something.

• Potential Energy is stored energy. The energy can be released and used - it just has not happened yet.

• An object can have both potential and kinetic energy.
