Question

The displacement-time graph of a moving body is given below.
Which of the following graphs would represent the velocity-time graph of the moving body?

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

• In a displacement-time graph, a line parallel to the x-axis means the displacement is not changing with time. So, the velocity of the body is also zero.
• Whenever there is a negative slope in the displacement-time graph, it means that the velocity of the body is constant and negative and vice versa.
• Similarly, for a positive slope in the displacement-time graph, the velocity is positive.
