It is used in Newton's formula for the gravitational force between two objects, which is:

${m_{1}},{m_{2}}\$ are the masses of each object

${r}\$ is the distance between the two objects.

g is the acceleration Earth's gravitational field exerts on objects at Earth's surface:

$g=9.81\ {\mbox{m}}\ {\mbox{sec}}^{-2}$
