Average Velocity

Three objects are shown in Animation 1.  View the animation and answer the following questions.

  1. Compare the average velocity of the objects from t=0 to t=9 s.
  2. For each object, describe how the average velocity during each 1-second time interval changes during its motion?
  3. During what time interval is the average velocity of the red ball approximately equal to the average velocity of the blue ball?
  4. During what time interval is the average velocity of the black ball approximately equal to the average velocity of the blue ball?  

Average Speed is not always equal to average velocity!

View the motion of the black ball shown in Animation 2 and answer the following questions.

  1. What is the average velocity of the object between t=0 and t=4.5 s?
  2. What is the average velocity of the object between t=4.5 s and t=9 s?
  3. What is the average velocity of the object between t=0 and t=9 s?
  4. What is the average speed of the object between t=0 and t=9 s?
