The figure shows a velocity-time graph for an object.  What does the AREA under a velocity-time curve represent?
ASpeed
BAcceleration
CDistance travelled
DForce
Answer & Solution
Correct answer: C. Distance travelled
The area under a v-t graph (between two times) equals the distance travelled in that interval. Geometrically: distance = average velocity × time, which is exactly the area of the v-t region between t₁ and t₂. This is one of the most useful graphical tools for kinematics.
