What is Kinetic Energy?

Kinetic Energy is energy of motion.

An object gets kinetic energy from its mass and velocity. An object with kinetic energy has energy stored in motion.

Potential Energy

Potential Energy is energy of position.

An object gets potential energy from height, mass and gravity. An object with potential energy has the potential to do work. This potential is only released when the object falls.
