COF has various meanings in the Tester category. Discover the full forms, definitions, and usage contexts of COF in Tester.
A coefficient of friction is a value that shows the relationship between the force of friction between two objects and thenormal force between the objects. It is a value that is used in physics sometimes to find an objects normal force or frictional force, when other methods aren't available.The coefficient of friction is shown by f = \mu F_{n}\,. In that equation, f is the frictional force, \mu is the coefficient of friction, and F_{n}\, is the normal force.
