Earth's force of gravity

Web1) First of all, you have Newton's Law of Universal Gravitation, that states that the force of attraction due to gravity between two masses, m and M, at a distance r, is given by F=GmM/r^2, where G is a constant called the gravitational constant. 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.
