What is friction? Define coefficient of static friction and coefficient of kinetic friction. Give the necessary formula for each.

Define coefficient of Kinetic friction. Give the necessary formulae.

What is friction? Define coefficient of static friction with necessary formulae

Explain static friction

Coefficient of static friction does not depend upon

Explain Kinetic Friction.

A 20 kg metal block is placed on a horizontal surface. The block just begins to slide when horizontal force of 100N is applied to it . Calculate the coefficient of static friction . If coefficient of kinetic friction is 0.4 then find minimum force to maintain its uniform motion.
