Force of ___________ is caused only when the surfaces of two bodies are in contact with each other
Hence, the force of FRICTION is caused only when the surfaces of two bodies are in contact with each other.
Friction is a force which opposes relative motion between two surfaces in contact with each other.
Two bodies need to be in contact with each other for a force to act between them.
Can a force exist between two bodies, if they are not in physical contact with each other? Illustrate by giving an example.
