Gravity is not stronger at the poles than at the equator. In fact, gravity is fairly consistent over the Earth's surface, regardless of location. The force of gravity is primarily determined by the mass of the Earth and the distance between an object and the Earth's center.
However, the rotation of the Earth does have an effect on the overall downward force experienced at different latitudes (i.e., the equator versus the poles). The Earth's rotation causes it to be slightly flattened at the poles and bulging at the equator, resulting in an oblate spheroid shape.
Due to this equatorial bulge, the distance between an object at the equator and the Earth's center is slightly greater compared to an object at the poles. As a result, objects at the equator experience a slightly weaker gravitational force compared to objects at the poles. This is because the force of gravity weakens with increasing distance from the center of mass.
To clarify, the difference in gravitational force between the equator and the poles is relatively small and generally not noticeable in everyday life. It would require extremely precise measurements to detect the variation in gravitational strength between these locations.
