 Clairaut's theorem (gravity)

Clairaut's theorem is a principle in classical physics related to the gravitational field produced by a rotating body. It states that the gravitational potential at the surface of a rotating spheroid (like Earth) is constant along surfaces of constant gravitational potential. More specifically, for a rotating mass, Clairaut's theorem implies that the gravitational acceleration can be expressed as a function of both the distance from the center of the object and the angular velocity (rotation rate) of the object.
