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}.
