Question

Which of the following options is correct for the object having a straight line motion represented by the following graph? <img class="img-fluid question-image" alt="Question" src="https://cdn.tardigrade.in/q/nta/p-0ljbwc4a5zo9qpe5.jpg" /> (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

Average velocity is defined as the displacement divided by time. In the given graph, displacement is zero. Hence, Average velocity=(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)=(0/t)=0

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

The object moves with constantly increasing velocity from $O$ to $A$ and then it moves with constant velocity.

Velocity of the object increases uniformly

Average velocity is zero

The graph shown is impossible

Average velocity is defined as the displacement divided by time.
In the given graph, displacement is zero.
Hence, $A v er a g e v e l oc i t y = \frac{t o t a l d i s pl a ce m e n t}{t o t a l t im e} = \frac{0}{t} = 0$
