प्रश्न

An object covers a distance of S meters in t seconds as follows :

S (meters) 0 8 20 20 16 10 0
t (Seconds) 80 2 5 10 12 15 10

Plot a graph, taking t on X-axis and S on Y-axis. Determine the velocity of the object at time
(i) 6 s, and
(ii) 14 s.

Is displacement a scalar quantity ?


A boy walks from his classroom to the bookshop along a straight corridor towards North. He covers a distance of 20 m in 25 seconds to reach the bookshop. After buying a book, he travels the same distance in the same time to reach back in the classroom. Find (a) average speed, and (b) average velocity, of the boy.


Can displacement be zero even if the distance is not zero? Give one example to explain your answer.


What can you say about the nature of motion of a body if its displacement-time graph is A straight line parallel to the time axis?


Figure given below shows a velocity-time graph for a car starting from rest. The graph has three parts AB, BC and CD.
