geopotential

[¦jē·ō·pə′ten·chəl]
(physics)
The potential energy of a unit mass relative to sea level, numerically equal to the work that would be done in lifting the unit mass from sea level to the height at which the mass is located, against the force of gravity.

Physics is required to understand the nature of gravitation or magnetics, they say, but their goal is to provide insight on how gravitation and magnetics can be geomathematically handled for the relevant observables, and how the resulting geopotential problems can be solved in a systematic, mathematically rigorous framework involving three-dimensional Euclidean space as well as spherical concepts.
