Kinetic energy is the energy created by the motion of an object. In classical mechanics, kinetic energy is calculated using the equation:

KE = 1/2 * m * v^2

(where KE = kinetic energy, m = mass, v = velocity)

Potential energy is energy that an object has simply due to its position and configuration. This energy can be caused by where it is in a force field. The most common potential energy is gravitational potential energy. There is also electrical, magnetic, and elastic potential energy. In classical mechanics, gravitational potential energy created by the Earth is calculated using:

PE = mgh

(where PE = potential energy, m = mass, g = acceleration due to gravity, h = height of the object)
