Question

State the four laws of kinetic friction.how does it avry from law of static friction

Answer 1

First law states that the friction is independent of the apparent area of contact between the contacting bodies.

 

Second law states that the friction force is proportional to the normal load between the contacting bodies.

 

Third law states that the kinetic friction is nearly independent of the speed of sliding.

 

First two laws are often referred to as Amontons laws and Coulomb introduced third law.
