Question

Plot the v-t graph for the following data and state the nature of motion the body:

V(m/s)	0	5	8	12	18	25	30	35	40	45
t(s)	2	4	6	8	10	12	14	16	18	20

Answer 1

We simply plot the points on the graph containing 

X axis as Time 

Y axis as Velocity 

Velocity v-s time graph of given data is

Deduction: We can easily see that the change in velocity per unit time is not constant. In other words velocity time graph is not a straight line, hence the motion is Non Uniformly Accelerated motion.
