Re: [Phys-l] A question about the Earth's gravity



Its only somewhat above the level of AP-C if centrifugal effects are deemed somewhat above the level AP-C

Subject: [Phys-l] A question about the Earth's gravity

We claim that the earth's gravity at its poles is slightly greater than
that at its equator. However, I feel justification for it is not
trivial but somewhat above the level of even AP Physics C; it will
require quite a bit of calculus! Would you agree?
