Non-contact forces

Non Contact Force can be defined as:

• Forces which come into play when two object do not have any physical contact between them.

• When a force is applied on some body by another object without any interaction or contact is called non contact force.

• In a Non-contact force the force information is transmitted over distance.

Examples of Non-Contact Forces are :

1. Gravitational force

2. Magnetic force

3. Electrostatics

4. Nuclear force

• It differs from the contact force in the sense that physical contact is not involved here.

• It is interesting to note that origin of all contact forces can be traced to non-contact forces.
