The shape of the Earth is not perfectly spherical, but rather a flattened spheroid with a bulge at the equator and a flattening at the poles. This non-uniform shape of the Earth affects the value of 'g', which is the acceleration due to gravity at a particular location. At the equator, the centrifugal force due to the Earth's rotation cancels out some of the gravitational force, resulting in a lower 'g' value. There is no centrifugal force at the poles and the value of 'g' is higher. Therefore, the value of 'g' varies depending on the latitude of the location.
