What is the nature of the distance time graphs for uniform and non-uniform motion of an object?

Distance-time graph is the plot of distance travelled by a body against time. So it will tell us about the journey made by a body and its speed.

(i) As in uniform motion, the distance time graph would be a straight line along with some slope, because the equal distance is covered in equal units of time.

(ii) For a non-uniform motion of an object, its distance-time graph is a curved line with an increasing or decreasing slope.
