Assertion: The position-time graph of a body moving uniformly in a straight line is parallel to position axis. Reason: The position-time graph in a non-uniform motion gives constant velocity at all instants of time.

If the position-time graph of a body moving uniformly in a straight line is parallel to position axis, it means that the position of body is changing at constant time, which is absurd and shows that the velocity of the body is infinite.
