DISTANCE – TIME GRAPHS
For an object in motion, the distance it has covered with time can be represented by a distancetime graph. [i.e. distance is on the vertical axis while time is on the horizontal axis]

 The area under the velocity - time graph gives the distance moved by the object.
 The gradient of the velocity - time graph give the acceleration of the object.
