Distance-time graphs show how the distance travelled by a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, going back to the ...

Example: Using the gradient or slope of a distance - time graph to work out the speed of an object. Calculate the speed of the object represented by the green line in the graph below, from 0 to 3 s.

If we draw distance time graph for uniform motion then it will be straight line. ... When a body moves along a straight line but with variable or change in speed is called non-uniform motion.
