Question

Q71) Which of the following can be zero for a moving body?

i) Average velocity

ii) Distance travelled

iii) Average speed

iv) Displacement

Options:

• A. a) i only
• B. b) ii and iii only
• C. c) iv only
• D. d) i and iv only

Answer 1

The correct option is D d) i and iv only

D)

Explanation: Velocity and displacement are vector quantities, whereas distance and speed are scalar quantities. Vectors also take into account the direction, which makes it possible for the average velocity and displacement to be zero for a moving body.
