Which of the following statements about the force of friction are accurate? (Choose all that apply) Increasing the surface area of an object will increase the force of friction. The force of friction acts in the direction opposite of motion. Increasing the mass of an object will increase the force of friction. All objects have the same coefficient of friction with each other. The force of friction is determined, in part, by the magnitude of the normal force. The force of friction decreases as velocity increases
