On a velocity-time graph, the area under the curve represents:
ATime
BDisplacement
CAcceleration
DAverage speed
Answer & Solution
Correct answer: B. Displacement
1. On a velocity-time graph, velocity is on the y-axis and time is on the x-axis.
2. The area of a small strip equals velocity times a small time interval.
3. By definition, velocity multiplied by time gives displacement.
4. Summing all strips gives the total displacement over the chosen interval.
5. So the area under a velocity-time graph represents displacement.
