Geopotential — is the potential of the Earth s gravity field. For convenience it is often defined as minus the potential energy per unit mass, so that the gravity vector is obtained as the gradient of this potential, without the minus.For geophysical… … Wikipedia
Geopotential function — is a function that at each point is equal to a constant minus the energy that would be acquired by a unit mass in falling from rest at infinity to the point in question. The gradient of the geopotential function, which can be obtained by vector… … Wikipedia
