Coefficient of Friction Equation and Table Chart

Static friction is friction between two or more solid objects that are not moving relative to each other. For example, static friction can prevent an object from sliding down a sloped surface. The coefficient of static friction, typically denoted as μ s,is usually higher than the coefficient of kinetic friction.
