Answer: Newton’s law of universal gravitation states that all particles attract all other particles in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
F = G m1m2 / r3
Where F is the gravitational force between the objects, m1 and m2 are the masses of the objects, r is the distance between the centers of the two objects, and G is the gravitational constant.
