Potential energy of gravity

The potential energy of gravity is the energy which a body because of its position in a field of Pesanteur has.

Example of terrestrial gravity

If one considers for example an object subjected to his weight on Ground and that one chooses the Sea level as origin of the potentials then this energy is worth

$$

E_p = mgz \,

With $g=9.81\; m.s^\; \{-\; 2\}\; \backslash ,$ the acceleration of terrestrial gravity, and $z\; \backslash ,$ the Altitude expressed in Meter S. Notons that this formula is valid only for low altitudes for which $g\; \backslash ,$ can be considered indeed constant.
