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


A driver of a car travelling at 52 km h−1 applies the brakes and accelerates uniformly in the opposite direction. The car stops in 5 s. Another driver going at 3 km h−1 in another car applies his brakes slowly and stops in 10 s. On the same graph paper, plot the speed versus time graphs for the two cars. Which of the two cars travelled farther after the brakes were applied?


Given figure shows the distance-time graph of three objects A, B and C. Study the graph and answer the following questions:

  2. Are all three ever at the same point on the road?
  3. How far has C travelled when B passes A?
  4. How far has B travelled by the time it passes C?
