Question
Which of the section(s) shown in the graph below indicate the body moving at a negative velocity?
- A only
- C only
- B only
- Both A and C
Hint:
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.
