Energy
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.
