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 ...

Speed and acceleration Speed-time graphs. The motion of any moving object can be described by its speed– time graph. ... This can also be called a constant or uniform speed.

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