The following is not a law of static friction:

The force of friction is dependent upon the area of contact

The magnitude of the limiting friction bears a constant ratio to the normal reaction between two surfaces

The force of friction always acts in a direction opposite to that in which the body tends to move

The force of friction depends upon the roughness of the surface
