Question

7. State the laws of friction​

Answer 1

Answer:

First law of friction: The amount of friction is proportional to the normal force exerted between the surfaces.

Second law of friction: Friction does not depend on the area of contact between the object and the surface.

Third law of friction: Friction force also depends on the nature of the surfaces in contact.

Answer 2

Answer:

The friction of the moving object is proportional and perpendicular to the normal force. . Kinetic friction is independent of velocity. The coefficient of static friction is greater than the coefficient of kinetic friction.
