    Do you mean the force of gravity at the poles of the earth?

    In that case, yes, I believe the force of gravity is greatest at the poles and weakest around the equator. That's because the earth isn't a perfect sphere; it's slightly flattened due to the tidal bulge around the equator. The ~24km difference between the radius at the poles versus the equator means that the force of gravity will be slightly higher at the poles.

    Furthermore, objects at the equator experience centripetal acceleration due to the earth's spin; objects at the poles do not. Thus if a person stands at the north pole, he'll weigh less than he would at the equator, because of both increased gravity at the poles and no centripetal force.

    Woops... I meant to say the person standing at the north pole weighs MORE than at the equator.
