The normal force is always perpendicular to the plane of contact, whereas the force due to friction is parallel to the plane of contact. When two objects slide against one another, which of the following statements about the force of friction between them is true? O The magnitude of the frictional force is always equal to lukn.. The magnitude of the frictional force is always less than un. > When two surfaces slide against each other, experiments show three things about the resulting kinetic frictional force fk: O The magnitude of the frictional force is determined by other forces on the objects so it can be either equal to or less than jikn. Submit Previous Answers Request Answer 1. The frictional force opposes the relative motion of the two surfaces at their point of contact. 2. The magnitude of the kinetic frictional force, fk, is proportional to the magnitude of the normal force, n 3. The ratio of fk to n is fairly constant over a wide range of speeds.
