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.
  
  The product of distance and time
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.
