Motion in Straight Line
Question
Wired Faculty App

Velocity-time graph of the motion is as shown in the figure.
Describe the motion of particle. What is the significance of shaded area?

Answer

From the graph given, we can infer that the particle starts from rest at t = 0 and accelerates uniformly, acquiring a velocity of 10 m/s in 5 sec.
Thereafter, the particle moves with a constant velocity.

The shaded area represents the displacement undergone by the particle during accelerated motion.
