Did you know that a man that weights 100 kg at the north pole will weight 669 g less at the equator?

Thats because the equator is further away from the center of gravity of our earth than the poles. And because the earth surface rotation is highest, leading to a centrifugal force that deletes part of the gravitational force.

For the autistics among us: of course his mass actually doesn't change. But he is pulled towards earth with .669% less force
