Question

Which of the section(s) shown in the graph below indicate the body moving at a negative velocity?

  1. A only
  2. C only
  3. B only
  4. Both A and C

hintHint:

B only

The correct answer is: B only


    Section B shows the negative velocity.
    Justification:
    The slope of the position-time graph represents the velocity. In section B the slope is negative as it is in a downward direction which shows that the velocity of the body is decreasing with time.
