117. CONCEPT QUESTIONS a. As the drawing shows, the normal force F N points perpendicular to the hill, while the weight W points vertically down. Since the car does not leave the surface of the hill, the magnitude of the perpendicular component of the weight W cos θ must equal the magnitude of the normal force, so F N = W cos . Thus, the magnitude of the normal force is less than the magnitude of the weight. b. As the hill becomes steeper, increases, and cos decreases. Consequently, the normal force decreases as the hill becomes steeper.
