Applications of velocity-time graphs

The variation of velocity with time can be represented graphically to calculate acceleration exactly like we calculated speed from distance-time graph. let me also help you with application of velocity - time graphs

Let us now plot a velocity-time (v- t) graph for the following data.

Velocity in m/s	0	10	20	30	40	50
Time in seconds	0	2	4	6	8	10

If the velocity-time data for such a car were graphed, then the resulting graph would look like the graph at the right. Note that a motion described as a changing, positive velocity results in a sloped line when plotted as a velocity-time graph. The slope of the line is positive, corresponding to the positive acceleration. Furthermore, only positive velocity values are plotted, corresponding to a motion with positive velocity.

The velocity vs. time graphs for the two types of motion - constant velocity and changing velocity (acceleration) - can be summarized as follows.

I hope my information on this topic would have helped a lot to understand more on this lesson. Keep reading and leave your valuable comments....
