# What is universal law of gravatation?

Newton’s law of universal gravitation states that a particle attracts every other particle in the universe using a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

F=G.(m1 x m2)/r^2

where:

F is the force between the masses;

G is the gravitational constant (6.674×10−11 N · (m/kg)2);

m1 is the first mass;

m2 is the second mass;

r is the distance between the centers of the masses.
