Conversation of Energy

5. Energy Review

Principles

Kinetic Energy is the energy of a system in motion.
Potential Energy is the "stored" energy of a system at rest.

Gravitational Potential Energy is the energy stored in an object above or below a fixed point.
Spring Potential Energy is the energy stored in a spring when it is compressed or stretched from its resting point.

The Law of Conversation of Energy states that energy can never be created nor destroyed-it can only be transferred from one form to another.
