How does the slope of a speed-time graph give the acceleration of a body moving along a straight line?

How will you use a speed-time graph to find whether the acceleration of the body is uniform or not?

The graph of one quantity versus another result in a straight line. How are the quantities related to each other?

Given on th e side are a few speed - time graphs for various objects moving along a stra ight line. Refer below figure. (a), (b), (c) and (d).

Which of these graphs represent
(a) Uni form motion
(b) Motion with speed increasing
(c) Motion with speed decreasing and
(d) Motion with speed oscillating.?

Draw the speed-time graph of a body when its initial speed is not zero and the speed increases uniformly with time.

Draw the speed-time graph of a body starting from some point P, gradually picking up speed, then running at a uniform speed and finally slowing down to stop at some point Q.

What can you conclude if the speed-time graph of a body is a curve moving upwards starting from the origin?

What can you conclude if the speed-time graph of a body is a straight line sloping upwards and not passing through the origin?
