Earth's force of gravity
WebThe first two factors imply a variation of gravity with latitude that can be calculated for an assumed shape for Earth. The third factor, which is the decrease in gravity with elevation, due to increased distance from the centre of Earth, amounts to −0.3086 milligal per metre.
