Learn the uses of equations and graphs of motion and how to determine other aspects of the motion of objects. BBC Bitesize Scotland Higher Physics revision.

Key fact The gradient of speed-time and velocity-time graphs represent acceleration. The area under a speed-time graph represents the distance travelled.

On the graph of velocity vs. time, Δ v /Δ t is the slope of the curve. If the curve is straight, the acceleration is constant. If the curve isn't straight we have to do the same trick we did before ...
