NOTE:If you see boxes in front of the choices, then there is more than one correct answer. If you see circles, there is only one correct answer.


Questions and Answers
  • 1. 
    For the graph shown above, describe the displacement, the velocity, and the acceleration of the object whose velocity (v) - time (t) graph is shown. Write your answers for the time intervals (a) 0 to 5 sec (b) 5 to 12 sec (c) 12 to 14 sec and (d) 14 to 15 sec.
  • 2. 
    Velocity is
    • A. 

      The rate of change of distance

    • B. 

      The rate of change of displacement

    • C. 

      A measure of how fast or how slow an object moves, in a particular direction

    • D. 

      The distance covered by an object times the time it took to cover that distance.

  • 3. 
    Acceleration is
    • A. 

      The rate of change of displacement

    • B. 

      The rate of change of velocity

    • C. 

      Measured in kilometers per hour

    • D.

  • 4. 
    An object moving at constant velocity has
    • A. 

      An increasing acceleration

    • B. 

      A decreasing acceleration

    • C. 

      A constant, nonzero acceleration

    • D. 

      Zero acceleration

  • 5. 
    The graph shows the displacement (x) of an object as a function of time (t). This shows an object that
    • A. 

      Is statonary.

    • B. 

      Is moving at constant velocity.

    • C. 

      Is moving at constant acceleration.

  • 6. 
    The graph shows the velocity (v) of an object as time (t) passes by. The object is
    • A. 

      Stationary.

    • B. 

      Moving at constant velocity.

    • C. 

      Moving at constant acceleration.

  • 7. 
    The graph shows the velocity (v) of an object as a function of time (t). This represents an object
    • A. 

      That starts from rest.

    • B. 

      That is moving at constant velocity.

    • C. 

      That is moving at constant acceleration.

    • D. 

      Whose velocity is increasing at a constant rate.

    • E. 

      Whose velocity is increasing at a changing rate.

  • 8. 
    The graph shows how the acceleration (a) of an object behaves as a function of time (t). this represents an object
    • A. 

      That is stationary.

    • B. 

      That is moving at constant velocity.

    • C. 

      That has zero acceleration.

  • 9. 
    From the given graph- if x represents displacement and t represents time, then the slope of the graph represents
    • A. 

      The velocity at any time.

    • B. 

      The acceleration at any time.

    • C. 

      The velocity only at the start of the motion.

    • D. 

      The velocity right before the end of the motion.

  • 10. 
    For the object whose graph is shown, check all the information below that is correct.
    • A. 

      The object started from rest.

    • B. 

      The object is at rest from t=60 to t=90 seconds.

    • C. 

      The object is slowing down from t=50 to t=60 seconds.

    • D. 

      The object changed direction only at the times at t=50 and t=90 seconds.

    • E. 

      The object had an acceleration at t=50 seconds.

    • F. 

      The object comes back to where it started at the end of 110 seconds.

  • 11. 
    For the graph shown, check all boxes that contain correct information.
    • A. 

      It is moving at constant velocity from A to B.

    • B. 

      It is accelerating from B to C.

    • C. 

      It is at rest from C to D.

    • D. 

      It is moving away from its starting point from A through D, and is coming back to its starting point from D to E.

    • E. 

      The magnitude of the velocity is larger from B to C, compared to the velocity from D to E.
