Velocity-time graphs show velocity on the vertical axis ... Between 4 and 7 seconds: the object is travelling at a constant velocity of 8 m/s. It travels \(3 \times 8 = 24~m\).

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.

It tells how much the object’s velocity changes due to constant acceleration over a specific time. s= ut+½ a(t^2)= This equation relates the object’s displacement, initial velocity ...

Here is a velocity vs time graph for this same situation ... What about the case of a constant acceleration? We can still find the displacement as the area under the curve by using a similar ...
