Olympiad Test: Motion And Time - Question 4

Which of the following graphs does not represent constant speed?

Detailed Solution for Olympiad Test: Motion And Time - Question 4

In a constant speed the change in position of the body remains the same for a particular interval of time. Break time axis into small parts and see the distance travelled in each of these parts is the same in choices A, B and C (zero in ‘C’). But the distance changes in ‘D’.

Olympiad Test: Motion And Time - Question 15

Study the graph given below. How is the speed of the moving body? Detailed Solution for Olympiad Test: Motion And Time - Question 15

Speed is the change of position of the body with respect to time. From the graph it can be seen that the change becomes less with time till there is no change at all i.e. till the speed becomes zero.
