LAB # 5 - Coefficient of static friction
... Friction is generally grouped in two classes; kinetic, in which the two surfaces are in relative motion and static, in which they are not. Empirically, it is often (but not invariably) found that the maximum static frictional force is directly proportional to the normal force of contact between the ...
