gravitational potential energy

Fr.: énergie potentielle gravitationnelle  

  1. The energy that an object possesses because of its position in a → gravitational field, especially an object near the surface of the Earth where the → gravitational acceleration can be assumed to be constant, at about 9.8 m s-2.

  2. In a two body system. It is the amount of work done in bringing the mass
    m to the distance R from M:
    EP = -GMm/R, where G is the → gravitational constant.

  3. For a uniform sphere. It is EP = -(3/5)GM2/R, where G is the gravitational constant and M is the mass contained in the sphere of radius R.

See also: → gravitational; → potential; → energy.
