Physics 211, Quiz 7A

Question 1:

Write any two of Newton's three laws of motion.

  Answer:  First Law: A body at rest stays at rest, and a body in motion
                      continues in motion with constant velocity,
                      unless acted upon by an external force.

           Second Law: When a force acts on a body, the body's acceleration
                       is directly proportional to the force, and 
                       inversely proportional to the body's mass.

                                F = ma

           Third Law: If a body exerts a force on a second body,
                      the second body exerts a force of equal magnitude,
                      but opposite direction, on the first.
