Question

what are characteristics of gravitational force

Answer 1

Characteristics of Gravity. Gravity is one of nature's four fundamental forces (the others are the electromagnetic force, the nuclear strongforce and the nuclear weak force). It is universal. (Only gravity and the electromagnetic force are apparent on a macroscopic scale.)
Unlike the electromagnetic force, gravity does not disguise itself as friction, drag, tension, compression or any sort of contact force.
 

Gravity is the weakest of the four fundamental forces, so weak that it can be completely ignored in interactions on a molecular scale and smaller.  The gravitation attraction between two electrons is roughly 1039 times weaker than their electrical repulsion.
 

Answer 2

Answer:

Characteristics of Gravitational Force

1. It is a universal attractive force.

2. It is directly proportional to the product of the masses of the two bodies.

3. It obeys inverse square law. It is a long range force and does not need any intervening medium for its operation. Gravitational force between two bodies does not depend upon the presence of other bodies.

4. It is the weakest force known in nature. It is a central force (i.e., it acts along the line joining the centers of the two bodies). It is a conservative force (i.e., work done in moving a body against the gravitational force is path independent). Gravitational- force between two bodies is thought to be caused by an exchange of a particle called graviton.
