The difference in weight at the equator and poles is due to the Earth's shape and rotation. The Earth is not a perfect sphere, but rather an oblate spheroid, meaning it is flattened at the poles and bulging at the equator. This bulge at the equator causes objects to weigh less compared to the poles, where the Earth's gravity is stronger.
The difference in weight between the equator and poles is very small, usually less than 1% of an object's total weight. This difference is due to the Earth's rotation, which causes the equator to experience centrifugal force, making objects feel slightly lighter.
No, the difference in weight between the equator and poles is so small that it has no noticeable effect on our daily lives. This difference only becomes significant when measuring very precise scientific experiments, such as with satellites or in geodesy.
Yes, there is a slight difference in weight between the North Pole and South Pole, but it is very small and not noticeable in everyday life. This is due to the Earth's rotation and the slight difference in shape between the two poles.
The difference in weight at the equator and poles does not affect gravity itself, but rather the perceived weight of objects. Gravity is a constant force that pulls objects towards the center of the Earth, but the Earth's rotation and shape can cause slight variations in how much objects weigh in different locations.
