Question

Friction that exists between two surfaces in contact, when there is no relative motion between them is called as?

Answer 1

1. Static friction is defined as the force which resists the force applied to an object and the given object will stay at rest until this static frictional force is overcome.
2. Therefore, if there is no relative motion between two surfaces in contact, the frictional force that exists between them must be a static frictional force.

Hence, the friction Friction that exists between two surfaces in contact, when there is no relative motion between them is called static friction.
