Instantaneous Velocity


The instantaneous velocity of an object can be found by the gradient of the displacement/time graph at a given time. 

In the above graph, which you can practise interactively below, the gradient, when the time, t = 1s, is as follows:
v = (3 - 0)/(1 - 0) = 3 m/s

You can practise the calculations interactively here; please move point:
