The fоrce оf frictiоn resists motion when two solid objects аre in contаct with one аnother. The direction is always opposite the direction of motion and parallel to the surfaces involved. There are two types of frictional forces, static - when the objects are at rest, and kinetic - when the objects are moving relative to one another. Identify ALL of the following examples that would be classified as static friction forces and NOT kinetic friction forces.
