You have done the activity and collected the data. You may have experienced something that you might not have thought of. Here are few questions for you to analyze what you have done.
If the motion for a particular time interval is uniform, what is the possibility of the motion becoming non-uniform if the time interval is shortened?
In principle, we can make the time interval shorter and shorter. But in reality, there is a limit to what we can measure. So the time interval should always be clearly specified.
If we analyze the data of all the runners in your class, we can find out who the fastest runner is and who is fastest in each segment. The running example gives you an idea about one kind of non-uniform motion where the change in velocity is irregular.
