The coefficient of friction is the ratio of the friction force to normal force. For example, if it takes 1 lb of force to slide a 10 lb weight along a level surface the coefficient of friction is 0.1. The coefficient depends on the two materials involved. Although the coefficient
Static friction is a force parallel to the two opposing surfaces that are stationary. For example, static friction can prevent an object from sliding down a sloped surface. The coefficient of static friction, typically denoted as s, is usually higher than the coefficient of kinetic friction as can be seen in the table above.
