Differentiate between a contact force and a force at distance ?

Answered by admin @ 20/08/2021

Contact force:

Contact force is a type of force acting on bodies when they are in physical contact with one another.

Contact forces are mainly facilitated by electromagnetic interaction between particles of the bodies.

Examples: Friction force, Reaction force, etc.

Non-Contact force:

Non-Contact force is a type of force acting on bodies even when the bodies are not in physical touch or contact with one another.

It is mainly facilitated by presence of special particles in the field like gravitons, etc.

Examples: Gravitational force, nuclear force, Electrostatic Force,etc.
