5 True/False questions

Newton, Galileo → Who proposed the laws of motion and whose work did he base his studies on?

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

For every action there is an equal but opposite reaction → In the formula for accelerated motion, what do the variables mean and what are the units for each variable?

inertia → What property of matter makes it want to continue to move indefinitely unless acted upon by an outside force?

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?
