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. The coefficient of friction is dimensionless and it does not have any unit. It is a scalar, meaning the direction of the force does not affect the physical quantity. The coefficient of friction depends on the objects that are causing friction. The value is usually between 0 and 1 but can be greater than 1. A value of 0 means there is no friction at all between the objects; such is possible with Superfluidity. All objects, otherwise, will have some friction when they touch each other. A value of 1 means the frictional force is equal to the normal force. It is a misconception that the coefficient of friction is limited to values between zero and one. A coefficient of friction that is more than one just means that the frictional force is stronger than the normal force. An object such as silicone rubber, for example, can have a coefficient of friction much greater than one. The friction force is the force exerted by a surface when an object moves across it - or makes an effort to move across it.
