Weight Vary With Latitude on Earth

Yes, our weight can vary slightly with latitude on Earth due to the planet's slightly oblate shape and the effects of the gravitational pull of the Moon and Sun.

The Earth's equatorial radius is approximately 6,378 kilometers, while its polar radius is approximately 6,357 kilometers. This means that the Earth's surface is slightly flattened at the poles and bulging at the equator due to its rotation. As a result, the strength of the gravitational pull of the Earth varies slightly with latitude.

At the equator, the gravitational pull is slightly weaker than at the poles due to the Earth's rotation. This means that objects weigh slightly less at the equator than they do at the poles. The difference in weight is very small, however, and is only noticeable for very precise measurements.

The effect of latitude on weight is known as the "latitude effect" or "geodetic effect." It is caused by the fact that the Earth's gravitational field is not perfectly spherical, but instead is slightly ellipsoidal. This means that the strength of the gravitational pull varies slightly depending on the location on the Earth's surface.

The latitude effect is most noticeable at the Earth's poles, where the gravitational pull is slightly stronger than at the equator. This means that objects weigh slightly more at the poles than they do at the equator. The difference in weight is very small, however, and is only noticeable for very precise measurements.

In summary, our weight can vary slightly with latitude on Earth due to the planet's slightly oblate shape and the effects of the gravitational pull of the Moon and Sun. The difference in weight is very small, however, and is only noticeable for very precise measurements.

Does our weight vary with latitude on Earth? If so, by how much?
