Question

Which of the following options is correct for the object having a straight line motion represented by the following graph?

• A. The object moves with constantly increasing velocity from $O$ to $A$ and then it moves with constant velocity.
• B. Velocity of the object increases uniformly
• C. Average velocity is zero
• D. The graph shown is impossible

Answer 1

Answer: (C)

Average velocity is defined as the displacement divided by time.
In the given graph, displacement is zero.
Hence, $Average \, velocity=\frac{t o t a l \, d i s p l a c e m e n t \, }{t o t a l \, t i m e}=\frac{0}{t}=0$
