The following is not a law of static friction:

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

The force of friction is dependent upon the area of contact
