How does the acceleration due to gravity ('g') change as a person moves from the Earth's equator towards the poles?

💡 Solution & Explanation

The acceleration due to gravity increases from the equator to the poles because the Earth is flattened at the poles, shortening the distance to the center, and because centrifugal force is lowest at the poles. Assuming constant gravity ignores the oblate spheroid geometry of the planet. This variation affects pendulum clocks and weight measurements globally.
