Using following data, draw time - displacement graph for a moving object:
Time (s) | 0 2 4 6 8 10 12 14 16 |
Displacement (m) | 2 4 4 4 6 4 2 0 |
Use this graph to find average velocity for first 4 s, for next 4 s and for last 6 s.
Average velocity =
Or V=1ms-1
For next 4s,
V = 0/4
V = 0 ms-1
As X(metre) remains the same from 4 to 8 seconds, velocity = 0
For last 6s,
V=
V = -6/6
V = -1ms-1
