Detailed explanation-1: -coefficient of friction, ratio of the frictional force resisting the motion of two surfaces in contact to the normal force pressing the two surfaces together. It is usually symbolized by the Greek letter mu (). Mathematically, = F/N, where F is the frictional force and N is the normal force.

Detailed explanation-2: -Definition. A newton (N) is the international unit of measure for force. One newton is equal to 1 kilogram meter per second squared. In plain English, 1 newton of force is the force required to accelerate an object with a mass of 1 kilogram 1 meter per second per second.
