Question

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

• A. The graph shown is impossible.
• B. Average velocity of the object is zero.
• C. The object is at rest.
• D. The object moves with constant velocity.

Answer 1

The correct option is B Average velocity of the object is zero.

According to given diagram, Total displacement $D=0$
Average velocity
$v_{av}=\frac{D}{T}=\frac{0}{T}=0$
Hence, average velocity is zero.
