- The magnitude (amount) of friction is proportional (increases / decreases as the other increases / decreases) to the what acting on the system?

5 True/False questions
F = net force, m = mass, a = acceleration → In the formula for accelerated motion, what do the variables mean and what are the units for each variable?
Friction → What property of matter makes it want to continue to move indefinitely unless acted upon by an outside force?
Perpendicular to the surface → In what direction is the "normal" force on a system?
Mechanical equilibrium → When the net force on a system is zero there is no motion and the system is said to be in a state of what?
The acceleration of a system is directly proportional to the force and inversely proportional to the mass, F = ma → Newton's third law is the law of action-reaction, what does this law state?
