Body weight varies with location on Earth’s surface due to differences in gravitational acceleration. It is not the same everywhere on Earth’s surface. At the poles (B), gravity is stronger because objects are closer to the Earth’s center. At the equator, the centrifugal force caused by Earth’s rotation counteracts some of the gravitational force, resulting in slightly lower weight. Therefore, body weight is maximum at the poles and slightly lower at the equator. Additionally, weight can vary with altitude. On hills (D), the distance from the Earth’s center is slightly greater compared to plains, resulting in slightly lower weight. However, this difference is generally negligible unless at extreme altitudes. Thus, body weight is not the same everywhere, being maximum at the poles and slightly lower at the equator.
