Which of the following distance-time graph (x-t) represents one-dimensional uniform motion?
✓ Correct answer: d) x t
ExplanationThe motion of an object traveling in a straight line can be represented on a distance-time graph, with the shape of the graph depending on whether the motion is uniform (straight line) or non-uniform (curved line).Uniform motion represents a constant change in displacement per second.The distance time graph for uniform motion is a straight line, that is, equal distance is covered by the equal units of time.Option (d) represents the graph where change in displacement per second is constant.Therefore, velocity is constant and hence it performs uniform motion.230
