Area under the curve of velocity-time graph gives_______?
Correct answer: A. Displacement
- A. Displacement
- B. Force
- C. Acceleration
- D. Momentum
Explanation
The area under a velocity-time graph is velocity multiplied by time, giving displacement, with unit metre (m). Students may choose acceleration because both are obtained from a velocity-time graph, but acceleration is given by its slope, not its area.

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.
