The gravitational potential at a point is equal to the work by the exterior force as a particle of unit mass is brought from infinity to its position in the gravitational field.doi:10.1017/S0305004108001904Frederic P. MillerAgnes F. Vandome...
The gravitational potential at a point in a gravitational field is the work done in bringing unit mass to this point from a point infinitely distant from the cause of the field; it is thus the potential energy of a particle of unit mass arising from the mass of a material body. ...

Hydrostatic balance is the first manifestation of the gravitational potential energy in fluid systems. It reflects the fact that the pressure at any point in a static fluid is determined by the weight of the fluid above it. In this chapter we give a general thermodynamic derivation of hydrostatic...
Gravitational potential energy (J) = work done to move a mass from one place to another through a gravitational field (use mgΔh or GMm(1/R1-1/R2). Gravitational potential (Jkg-1) = work done per unit mass to move a small object from infinity to that point (V=W/m). ...

关于gravitational potential energy 的理解Gravitational Potential EnergyThe general expression for gravitational potential energy arises from the law of gravity and is equal to the work done against gravity to bring a mass to a given point in space....
gravitational potential energy of the system. Because gravitational potential energy depends on relative position, we need a reference level at which to set the potential energy equal to 0. We usually choose this point to be Earth’s surface, but this point is arbitrary; what is important is ...
