Hence, the only things you need to calculate GPE are the mass of the object and the height of the object above the surface. In Potential Energy and Conservation of Energy, we showed that the change in gravitational potential energy near Earth’s surface is U m g ( y 2 y 1). The acceleration due to Earth’s gravity has a (roughly) constant value anywhere on the surface and points directly to the centre of mass of the planet: g 9.81 m/s2. It depends on 3 things: the force of gravity (9. ![]() Located at: en./wiki/Physics_with_Calculus/Mechanics/Gravitational_Potential_Energy. Potential energy is particularly useful for forces that change with position, as the gravitational force does over large distances. Gravitational Potential Energy (GPE) is the energy of place or position.
