1.7 Determine acceleration from the gradient of a velocity-time graph

Acceleration = gradient of graph



Gradient = Rise ÷ Run
[Change in y (rise) ÷ change in x (run)]

In figure 1, the rise would be the dotted line and the run would be how far it is, i.e. from 2 to 6 on the graph below. Let's say that each dash on the y axis represents 1 (i.e. the scale goes 1, 2, 3, 4 etc)

So, if you were to calculate the acceleration:
G = rise ÷ run
= 4 ÷ 5
= 0.8 m/s^2
