Gravitational potential energy is the energy an object has due to its position above Earth, energy due to its height. We know this energy exists because it takes effort to lift an object up to a height and also because when we release an object, it falls, gaining kinetic energy.
Ug = -Gm1m2/rÂ² The potential energy from gravity between two objects (Ug) is equal to the negative universal gravitation constant (-G) times the mass of the first object (m1) times the mass of the second object (m2) all divided by the distance between the objects squared (rÂ²).
