How will you show the distance time graph of
(a) an object at rest
(b) an object which is moving with constant speed
(c) an object which is moving with non-uniform motion

Explanation:

Here we have to consider the gradient of the graph.

Gradient = ( Distance / Time ) = Speed

For

(a) Gradient is zero there fore straight line

(b) For uniform speed ( Constant speed ) gradient is constant .

(c) For none uniform motion gradient is not constant
