Properties of Gravitational force:
1. Gravitational force is always attractive. For example, earth always attracts us but never repels.
2. It is weakest force in nature.
3. It obeys inverse square law. Let us discuss it:
If there are two objects of mass m1 and m2 and they are placed at distance r apart. Then force between them will be:
F = G(m1m2)/r2
4. Gravitational force is a central force.
5. It is a conservative force.
6. They can operate over a very long distances.
7. Graviton is the particle exchanged when the two masses attract through gravitational force. This exchanged particle is called graviton.

Gravitational force is always an attractive force.
2. Gravitational force between two bodies is independent of the medium between them.
3. Gravitational force is a long range force.
4. Gravitational force act along the line joining the centers of the two bodies.
Gravitational force is the force of attraction between any two objects.
Static electric force or electrostatic force is the force of attraction or repulsion between two charged particles.
Magnetic force is the force of attraction or repulsion arises between two charged particles because of their motion.
All the three forces work at a distance, without coming in physical contact with the object.
