Coefficient Of Friction (Dynamic)

Glossary Term

Definition and Purpose

The dynamic coefficient of friction (COF) is a measure of the resistance to motion that occurs when two contacting surfaces slide over each other under an applied load. It is quantified as the ratio of the tangential force required to maintain the motion of the surfaces to the perpendicular force pressing them together. This property is crucial in understanding and predicting the behavior of moving parts in various applications, from industrial machinery to everyday objects.
