Page 4 - Lesson Notes

10m, when time is 4 sec the distance is 20m. We can say there is an equal increase
with equal intervals of time.
So, the information we get is:

 Body is moving with uniform speed

When d-t graph is not a straight line

If we look at the markings carefully we observe, that when time is 2 sec then distance is
10m, when time is 5 sec the distance is 20m. We can say there is an unequal increase
with equal intervals of time.
So, the information we get:

 This shows body is moving with non uniform speed.

Velocity Time -Graph

Like we took so many examples above so, in any example if we plot velocity versus
time, then we get the important information from it.

 It represents acceleration

 The area enclosed under graph gives displacement

When v-t graph is || to time axis
