with R being the radius of the Earth. Given the Earth complete one revolution per day, this means g is reduced by 0.00346 m s<sup>-1</sup> or 0.346% at the equator compared to the poles.<ref>[https://www-spof.gsfc.nasa.gov/stargaze/Srotfram1.htm www-spof.gsfc.nasa.gov]</ref> This means that a object [[weight|weighs]] less at the [[equator]] than at the poles.

Centrifugal force also plays a more subtle effect. It causes the equator regions to bulge out and the poles to flattern. This distorts the [[Earth]] from being a [[sphere]] into a squashed sphere known as an "oblate spheroid". This adds to the effect mentioned above as it means a point on Earth's surface is further away from the centre at the equator than at the poles and so g is less there anyway.
