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 calculus, yields the Earth's gravitational field.
Famous quotes containing the word function:
“Advocating the mere tolerance of difference between women is the grossest reformism. It is a total denial of the creative function of difference in our lives. Difference must be not merely tolerated, but seen as a fund of necessary polarities between which our creativity can spark like a dialectic.”
—Audre Lorde (1934–1992)
