Question

basic properties of gravitational force​

Answer 1

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.
