75. Is it true that gravity is stronger at the north pole than at the equator. Does that mean that a person would be able to jump higher at the equator?
Yes. Because of its rotation, the earth isn't quite spherical and people near the poles of the earth experience stronger gravity than at the equator. At the equator, they would experience an apparent weight that was 1% less than at the poles and would be able to jump higher as a result. The Olympic committee should take note.
