Can displacement-time sketch be parallel to the displacement axis ? Give reason to your answer.
Answer
No, the displacement-time sketch can never be a straight line, parallel to the displacement axis because such a line would mean that the distance covered by the body in a certain direction increases without any increase in time (i.e., the velocity of the body is infinite) which is impossible.
