Using the following data, draw a time displacement graph for a moving object:
Time (s) 0 2 4 6 8 10 12 14 16
Displacement (m) 0 2 4 4 4 6 4 2 0
Use this graph to find the average velocity for the first 4 s, for the next 4 s, and for the last 6 s.
Explanation:-
By using the data given in the table, if we draw the displacement time graph, it will look as shown:
Average velocity is displacement divided by time in any time interval. In the first four seconds, it has traveled four meters hence average velocity will be 1 m/s. For the next four seconds, its position is not changing. This means it is not moving. Hence, its average velocity will be zero.
- In the last six seconds, from t = 10 to t = 16 sec, it has changed its position from 6 m to 0 m. Hence, in this time interval, displacement is 6 m and time is also 6 seconds.
- Therefore, the average velocity will be 1 m/s.
