Static friction Guide, Meaning , Facts, Information and Description
Determining the Coefficient of Friction.
Friction is a resistive force that prevents two objects from sliding freely against each other. The coefficient of friction (μ) is a non dimensional number, the ratio of the resistive force of friction (Fr) and by the normal or perpendicular force (Fn) pushing the objects together. It is represented by the equation:
μ = Fr / Fn.
There are different types and values for the coefficient of friction, depending on the type of resistive force. The coefficient of friction can be determined through experiments, such as measuring the force required to overcome friction or measuring the angle at which an object will start to slide off an incline.
