Law of Universal Gravitation

Law of Universal Gravitation

$$$F = G \; {m_1 m_2 \over r^2}$$$

Newton's law of universal gravitation states that every point mass attracts every single other point mass by a force pointing along the line intersecting both points. The force is proportional to the product of the two masses and inversely proportional to the square of the distance between them.

$$F$$ = the force between the masses $$G$$ = the gravitational constant $$m1$$= the first mass $$m2$$ = the second mass $$r$$ = distance between the centres of the masses.
