प्रश्न
If on a round trip you travel 6 km and then arrive back home :
What is your final displacement ?
Advertisements
उत्तर
Displacement is calculated from the initial and final positions of a body. It is independent of the path covered. So, displacement in this case is 0 because the initial and final positions are the same.

Can displacement be zero even if the distance is not zero? Give one example to explain your answer.
Figure (a) shows the velocity-time graph for the motion of a body. Use it to find the displacement of the body at t = 1 s, 2 s, 3 s and 4 s, then draw on Figure (b), the displacement-time graph for it.
