Laws of Kinetic Friction

The force of kinetic friction opposes the relative motion between two surfaces in contact.

1. The force of kinetic friction opposes the relative motion between two surfaces in contact.

2. The force of kinetic friction is directly proportional to the normal reaction between the two surfaces in contact i.e.,

where μk is the coefficient of kinetic friction.

3. Force of kinetic friction is independent of the area of the two surfaces in contact.

4. Force of kinetic friction depends on the nature and material of the two surfaces in contact.

5. Force of kinetic friction is independent of velocity for small velocities.
