If an apple falls a distance of 2 meters in its first second of fall, then 2 meters in its next second of fall, and again 2 meters during its third second of fall, the acceleration of the apple is
 
  1) 0 m/s2.
  2) 2 m/s2.
  3) 4 m/s2.
  4) 10 m/s2.
  5) actually, more than 10 m/s2.
 
  This is because
  6) no change in velocity occurs during fall.
  7) the apple increases in distance by 2 meters for each successive second.
  8) the average velocity is 1 m/s for each successive second.
  9) its weight is counterbalanced by its inertia.

Question 2

An object drops in free fall. At one instant it is moving at a speed of 50 meters per second. Exactly one second later its speed is about
 
  1) 10 m/s.
  2) 50 m/s.
  3) 60 m/s.
  4) 100 m/s.
 
  This is because
  5) no net force acts on the object while in its state of free fall.
  6) it gains a speed of about 10 m/s for each second of fall.
  7) its velocity nearly doubles each second.
