Gravity and angular momentum

Well, again I'd say no.

Do you weigh more at the North Pole than you do at the equator?

Do you weigh less at the top of a mountain?

If you wanted to be extremely precise, the answer to both would be yes. You're closer to the center of the Earth at the poles and you have zero velocity relative to the center of the Earth. You're further from the center of the Earth on top of a mountain, which also means you have a higher linear velocity (angular velocity has to stay constant).

For all practical purposes, though, your weight (the measurement of the net force of gravity on your body) will be the same anywhere on the surface of the Earth.
