Question
What is the nature of the distance-time graphs for uniform and non-uniform motion of an object?
Solution
The distance-time graph for the the uniform motion of an object is a straight line (as shown in the following figure).
The distance-time graph for an object's non-uniform motion is a curved line (as shown in the given figure).

The distance between Bholu’s and Golu’s house is 9 km. Bholu has to attend Golu’s birthday party at 7 o’clock. He started from his home at 6 o’clock on his bicycle and covered a distance of 6 km in 40 minutes. At that point, he met Chintu and spoke to him for 5 minutes and reached Golu’s birthday party at 7 o’clock. With what speed did he cover the second part of the journey? Calculate his average speed for the entire journey.
The slope of the distance-time graph indicates the speed.
Assertion: The position-time graph of a uniform motion in one dimension of a body can have a negative slope
Reason: When the speed of the body decreases with time then, the position-time graph of the moving body has a negative slope.
