Question

what are the laws of friction​

Answer 1

Answer:

THE FIVE LAWS OF FRICTION.

When an object is moving, the friction is proportional and perpendicular to the normal force (N) Friction is independent of the area of contact so long as there is an area of contact. The coefficient of static friction is slightly greater than the coefficient of kinetic friction

Answer 2

when a body is moving the friction is directly proportional to the normal force and the friction is perpendicular to the normal force

friction does not depend on the area of contact so long as there is an contact

kinectic friction is independent to the velocity of the body

friction depends on type is surface in contacts

the coefficient of static friction is slightly higher the value than that of the kinectic friction
