acceleration of free fall


Show Summary Details

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/s2; 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/R2, where M is the mass of the body, R is its radius, and G is the universal gravitational constant.
