Quiz

1.  Speed = distance / time.  Speed & direction => velocity.  Change in velocity => acceleration. Momentum = mass x velocity.  Force causes change in momentum, producing acceleration
2. Mass = quantity of matter. Weight = force acting on mass
3.  He discovered laws of motion & gravitation.  He realized these same laws of physics were identical in the universe and on Earth
4.  Object moves at constant velocity if no net force is acting. Force = mass × acceleration. For every force there is an equal and opposite reaction force.
