Potential and Kinetic Energy
... Potential energy is stored energy. The formula for the potential energy of an object is: Ep = mgh where m equals mass in kilograms, g is the acceleration of gravity, and h equals the height of the object. The mass (m) of the object times the acceleration of gravity (g) is the same as the weight of t ...
