Answer 2

Average velocity and displacement can sometimes be 'zero' for a moving body. (Option c)

• Displacement is the change in position of a body along a direction with time.
• Average velocity is the change in this displacement divided by the time interval taken for these position changes.
• Displacement and velocity are vector quantities, which means direction has a very important role in the case of these quantities.
• If the body starts off from a point and then comes back to the same point, even if it has traveled and is in motion, the displacement will be zero.
• Since, the average velocity is the change in this displacement, when displacement becomes zero the average velocity also becomes zero.
