Newton’s Law of Universal Gravitation states that every particle attracts every other particle in the universe with a force that is directly proportional to the product of the masses and inversely proportional to the square of the distance between them.
As per the universal law of Gravitation, every object in the universe attracts every other object by the force of attraction which is directly proportional to the product of masses of the objects and is inversely proportional to the square of the distance between them. This is mathematically given as:
F = G(mM/d2)
Where,
F is the force of the gravitational pull
G is the constant known as the gravitational constant
M is the mass of object 1
m is the mass of the object 2
d is the distance between object 1 and object 2
The importance of universal law of gravitation lies in the fact that it was successful in explaining many phenomena such as:how different objects in this universe affect others
how gravity is responsible for the weight of a body and keeps us on the ground
how lunar motion occurs around the earth
how planetary motion takes place
how the tidal waves originate
