But I do know v 1 (it starts at rest ... The slope of the velocity-time graph is the average acceleration. You can see the fitting equation gives an average acceleration of 6 x 10 4 m/s 2.

Save guides, add subjects and pick up where you left off with your BBC account. The gradient of a velocity-time graph at a particular time gives the acceleration of the object at that time.

Select "v: velocity magnitude ... as a the magnitude of the acceleration and change in velocity so it matches up with our graph. Since the graph is velocity vs. time, the change in velocity ...
