The coefficient of friction (fr) is a number that represents the ratio of the frictional resistive force (Fr) divided by the normal or perpendicular force (N) pushing the objects together. The equation fr = Fr/N represents it.
Friction is a resistive force that prevents two objects from freely sliding against one another. The coefficient of friction (fr) is the ratio of the frictional resistive force (Fr) divided by the normal or perpendicular force (N) pushing the objects together. It is denoted by the equation fr = Fr/N.
The coefficient of friction has different types and values depending on the type of resistive force. Experiments, such as measuring the force required to overcome friction or the angle at which an object begins to slide off an incline, can be used to determine the coefficient of friction. There are also charts available of common coefficients of friction.
The static, deformation, and molecular coefficients of friction are combined in the rolling coefficient of friction. This coefficient of friction can be reduced significantly.
