5 True/False Questions

  1. Opposite directionThe friction vector acts in what direction with respect to the system's motion?

          

  2. For every action there is an equal but opposite reactionNewton's third law is the law of action-reaction, what does this law state?

          

  3. Perpendicular to the surfaceThe magnitude (amount) of friction is proportional (increases / decreases as the other increases / decreases) to the what acting on the system?

          

  4. inertiaWhat property of matter makes it want to continue to move indefinitely unless acted upon by an outside force?

          

  5. The acceleration of a system is directly proportional to the force and inversely proportional to the mass, F = maNewton's second law is the law of accelerated motion, what does this law state and what is the formula that goes along with the law?
