The velocity time graphs give all three variables for motion–velocity which can be read off at any time. Area is displacement and gradient is acceleration. Next page ...

Such graphs are known as displacement-time graphs. Sections A and C show travelling away from home. Sections B and D are when the journey has paused for a rest or a wait.

Acceleration (a)- the rate of change of an object’s velocity over time. Displacement (s)- the total distance and the direction the object travels.
