Static Friction
Description
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 static friction force must be overcome by an applied force before an object can move.The maximum value of static friction, when motion is impending, is sometimes referred to as limiting friction or traction. The maximum possible friction force between two surfaces before sliding begins is the product of the coefficient of static friction and the normal force.
