* Gravity and Centrifugal Force: The Earth's gravity pulls everything towards its center. However, the Earth's rotation creates a centrifugal force that pushes things outwards, particularly at the equator.

* Equator's Distance: The equator is the farthest point from the Earth's center, meaning the centrifugal force there is strongest. This force counteracts a small portion of gravity, resulting in a slightly lower weight.

Earth's Center: While gravity is strongest at the Earth's center, this doesn't mean you would weigh the least there. You would actually experience weightlessness at the Earth's center because the gravitational pull from all sides would cancel each other out.

In summary:

* Equator: Least weight due to the centrifugal force counteracting gravity.

* Earth's Center: Weightless due to equal gravitational pull in all directions.
