The area under a velocity-time graph represents
Correct answer: B. displacement
- A. acceleration
- B. displacement
- C. force
- D. momentum
Explanation
Multiplying velocity by time gives displacement, so the area enclosed between the curve and the time axis is the displacement travelled. The gradient of the same graph gives acceleration. On a displacement-time graph, by contrast, the gradient is velocity and the area has no useful physical meaning.

About Displacement and Velocity
Displacement is the directed change in position, while velocity is the rate of change of displacement and includes both magnitude and direction. The topic connects position-time and velocity-time graphs with average and instantaneous values, and distinguishes displacement from distance and velocity from speed.
