A coefficient of friction is a value that shows the relationship between the force of friction between two objects and the normal reaction between the objects that are involved. It is a value that is sometimes used in physics to find an object's normal force or frictional force when other methods are unavailable. The coefficient of friction is shown by {\displaystyle F_{f}=\mu F_{n}\,} {\displaystyle F_{f}=\mu F_{n}\,} . In that equation, {\displaystyle F_{f}} {\displaystyle F_{f}} is the frictional force, {\displaystyle \mu } \mu is the coefficient of friction, and {\displaystyle F_{n}\,} F_{n}\, is the normal force. The coefficient {\displaystyle \mu } \mu can be two different things. It is either the coefficient of static friction {\displaystyle \mu _{s}} \mu_s, or the coefficient of Dynamic friction {\displaystyle \mu _{k}} \mu_k.The coefficient of static friction is the friction force between two objects when neither of the objects is moving. The coefficient of dynamic friction is the force between two objects when one object is moving, or if two objects are moving against one another. So let's start to watch video and understand the concept of Coefficient of friction ......... Extraclass.com in an initiative of IIT-Bombay Alumnus to organize the home tutoring industry of India.
