If the motion of an object is represented by a straight line parallel to the time axis in a distance-time graph, then the object undergoes

In a distance-time graph, the distance is plotted on the vertical (Y) axis and time on the horizontal (X) axis [1]. The slope of the line in such a graph represents the speed or velocity of the object. When the graph is a straight line parallel to the time axis, the distance remains constant as time progresses. This indicates that the object is not covering any distance over time, meaning its speed is zero. A horizontal line with zero slope on a distance-time graph signifies that the object is at rest or has zero velocity. In contrast, a straight line with a constant positive slope would represent uniform non-zero velocity, while curved lines would indicate accelerated or decelerated motion. Therefore, a line parallel to the time axis uniquely represents zero velocity motion.
