No applied force, A small applied force (not be able to move the block) static friction opposes the applied force Static Friction applied force increases, to a critical value, no static friction static friction increases along, block is on the verge of moving Block is sliding Friction is KINETIC max , s f reaches its maximum value Chapter 6 •As the force applied to an object increases, so does the force of static friction. N s s F f μ = max , Static Friction (summary) F N is the normal force between the two surfaces. •Static friction has a maximum value . •The maximum static friction is •As long as the object remains at rest, the static friction cancels the applied force (net force = 0) ----Newton’s first law When the applied force is equal to this value, static friction reaches this maximum value accordingly. The object is on the verge of moving , but not yet. Net force = 0, --- Newton’s first law max , s f s μ is called the coefficient of static friction (no unit) •When the applied force exceeds
