प्रश्न
What information about the motion of a body are obtained from the displacement-time graph?

उत्तर
From displacement-time graph, the nature of motion (or state of rest) can be understood. The slope of this graph gives the value of velocity of the body at any instant of time, using which the velocity-time graph can also be drawn.
