Question

A body with an initial velocity x moves with a uniform acceleration y, plot its velocity time graph.

Answer 1

In this question we have initial velocity x and uniform acceleration y. To plot a velocity time graph we will consider one axis as velocity and other as time. Then we will draw a line joining the two which will show the acceleration of the body.

Complete solution:
We will consider x- axis as time axis and y- axis as velocity axis. As we are given that the initial velocity is x and acceleration is y. let t is time. To plot its graph we have marked x on the velocity axis. It may also be called the intercept on the velocity axis. On the time axis ‘t’ is marked which shows the time taken. Then we will connect the respective lines of velocity and time. This line shows uniform acceleration y. So, in this way we can plot the velocity time graph of any case.

Above plot shows a velocity time graph of a body having initial velocity x and uniform acceleration y.

Note: This is the way to plot a velocity time graph. A velocity time graph gives acceleration. Using the same way we can plot the distance time graph. Distance- time graph gives velocity of those quantities. In some questions this may be the case that we are given a graph and using that graph we have to find a quantity. We have to be careful while taking reading from the graph in such a type of question.
