The English physicist Sir Isaac Newton developed his theory of the gravitational force in his famous work Philosophice Naturalis Principia Mathematica. In modern language and notation, it states that the force $F$ between two point masses $m_{1}$ and $m_{2}$ separated by a distance $r$ is given by

$F=-G \frac{m_{1} m_{2}}{r^{2}}$
