Earth's surface gravity
WebThe acceleration g varies by about 1/2 of 1 percent with position on Earth’s surface, from about 9.78 metres per second per second at the Equator to approximately 9.83 metres per second per second at the poles. In addition to this broad-scale variation, local variations of a few parts in 10 6 or smaller are caused by variations in the density ...
