 What is gravitation.friends today iam asking about gravitation.friends what is gravitation.

Gravitation is defined as the non con tract force of attraction of any two body's.in the univers.the earth attracts all the body toards its centre .the force with which the earth pullos the bodies towards .it is called the gravitational force of earth or gravity of the earth 

Charastic of gravitational force:-

Gravitational force is action at a distance force it does not need any contact between the two bodies.

Gravitational force between two bodies form action reaction pair.theforce exerted by two bodies..

Gravitation force two bodies from action reaction pair .the force extended by two bodies on each other are equal in magnitude opposite in direction.gravitional for is the weakest force in nature.

Gravitional force is 10'36time smaller than the electrostatic force and 10'38 times smaller than the nuclear force.

Gravitional force between two small bodies is very small body on the other hand gravitational force between two large bodies  is large.

Gravitational force is an inverse suare force because it inversely proportional to the square of the distance between two bodies.

Law of gravition given by newton.according to this law ,,attrative force between two bodies univese is directly proportional to the product of the masses and inversely proportional to the squre distance between them.

Consider two bodies Aand B having masses m1andm2 whose centre are ata distance r for a each other.

The law of gravition is applicable for .
