State the universal law of gravitation.

(N/A) The universal law of gravitation states that every object in the universe attracts every other object with a force that is directly proportional to the product of their masses ($M_1$ and $M_2$) and inversely proportional to the square of the distance $(d^2)$ between their centers.
Mathematically,this is expressed as: $F = G \frac{M_1 M_2}{d^2}$,where $F$ is the gravitational force and $G$ is the universal gravitational constant.
