Get QuoteA pendulum swings slower at the equator for two reasons 1. A centrifugal force of r 2 from the Earths rotation decreases the acceleration by 0.034 m s 2, but this does not occur at the north pole and south pole. 2. The Earth bulges at the equator, so any place there is further from the centre of the Earth.
