help please

Because the earth is not a perfect sphere, it is somewhat "flattened" at the poles. The pull if gravity is strongest towards the center of the earth, therefor, if you are at the poles, you are minimally closer to the center of the earth than if you are the equator, which is the widest part of the earth. In addition, the centrifugal force of the earth's rotation is greatest at the equator, and this counterbalances the force of the pull of gravity, which also assists in a person weighing more at the poles.

It's not much of a difference. You'd probably weight one or two pounds more at the poles than you would at the equator.

hope that helped.

Yes , really helped , thank you!!!!!!
