How does rotation impact gravity?

Best Answers

So then does rotation of the earth contribute to its gravitational field? The answer is yes. In the General Theory of Relativity, the source of gravity is the stress energy tensor of a body, not just its mass. So any kind of energy and motion adds to the Earth's gravity. read more

Regarding acceleration due to gravity, and gravity only, the only influence due to the rotation of earth is the 40+km bulge in the Equator, which causes objects to be that much farther from the center of gravity of the Earth than at the poles. read more
