Universal Law of Gravitation

Newton's Universal Law of Gravitation states that
where
m
_{1}
and
m
_{2}
are the masses of any two objects under consideration and
r
_{1}
and
r
_{2}
are their respective position vectors.
Gravitational Constant

This the G that appears as a constant of proportionality in Newton's Universal
Law of Gravitation. It has a value of
6.67×10^{11}
Nm
^{2}
/kg
^{2}
.
