Detailed explanation-1: -If an object is not moving, the distance-time graph results in a horizontal line which shows that the object is at rest.
Detailed explanation-2: -A straight line on a distance-time graph represents that a particle has constant speed.
Detailed explanation-3: -We generally put position on the y-axis, and time on the x-axis. We call this a linear graph. The slope of this line will be the average velocity of our object. If the graph is flat or horizontal, then the object is not moving, the slope is zero, and the velocity is zero.
Detailed explanation-4: -Distance is measured on the vertical axis, and time is measured on the horizontal axis. Remember that a straight, sloped line on a distance–time graph represents motion at a constant speed. In addition, a straight horizontal line on a distance–time graph represents the fact that an object is stationary.
Detailed explanation-5: -The steeper the graph, the greater the acceleration. A horizontal line means the object is moving at a constant speed. A downward sloping line means the object is slowing down.
