Question 4 Which of the following best describes the directions of friction and normal force? Your answer: Friction is always horizontal and normal force is always vertical. Friction is always horizontal and normal force is always perpendicular to the surface. Friction is always parallel to the surface and nomal force is always vertical. Friction is always parallel to the surface and normal force is always perpendicular to the surface. There is no consistent pattem.
