## Quick Reference

(*g*)

The acceleration experienced by an object falling freely in a gravitational field, also known as the acceleration due to gravity. Its mean value at the Earth's surface is 9.807 m/s^{2}; this varies slightly with latitude, because the Earth is not perfectly spherical. On any body the acceleration due to gravity can be found from the formula *g = GM/R*^{2}, where *M* is the mass of the body, *R* is its radius, and *G* is the universal gravitational constant.
