Kinetic, Potential, and Conversation of Energy

Potential Energy

Potential energy is the stored energy of position possessed by an object

For example, a car has potential energy while at rest. Another example is when a wrecking ball in being held in the air it has potential energy.

Kinetic Energy

Kinetic energy is energy of movement. It's a scalar quantity and doesn't have a direction. Kinetic energy is completely described by magnitude alone.

For example, when you start moving the wrecking ball to tear down a building the wrecking ball has kinetic energy.

Conversation of Energy

The Conversation of Energy states that energy can be neither created or destroyed.
