Coefficient of friction, ratio of the frictional force resisting the motion of two surfaces in contact to the normal force pressing the two surfaces together. The coefficient of friction has different values for static friction and kinetic friction.
A coefficient of friction equation can also be known as the coefficient of friction formula. It is clear from equation (3) that friction causes force to be directly proportional to the friction coefficient. It stands to reason that if the coefficient of friction is greater, then the force of ...

The friction force is best defined using an equation. The force of friction depends on the friction coefficient for the type of friction under consideration and the magnitude of the normal force that the surface exerts on the object. For sliding friction, the frictional force is given by: \(F...

Mass doesn't affect the friction coefficient, regardless of whether we're considering the coefficient of static friction formula or the kinetic case. Since both friction and normal force are proportional to mass, it cancels out when we divide them to calculate the coefficient of friction. What is...
Piezoelectric devices can be used to monitor frequencies as high as 25 [kHz] [3] so that even very rapid variations in friction force can be measured. However, it should be realized that the mass of the structure supporting the friction specimen will reduce the frequency limit of any ...
A friction coefficient between the piston and the working cylinder is represented by the formula whereby the coefficient is equal to or less than 3h2/rl, where r is the radius of the piston, 2h is the height of the piston and l is the length of a section of the rod which is ...

The capstan formula also neglects frictional resistance that is not dependent on lateral stress (adhesion) and sometimes gives incorrect results. For these reasons, the value of static and of kinetic coefficients of friction may be considered only as approximate values. The lower the input tension,...
