प्रश्न
Can displacement-time sketch be parallel to the displacement axis? Give a reason to your answer.

उत्तर
The displacement-time graph can never be 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, which is not possible.
