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.

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.

Uniform Motion in a Straight Line. ... The slope of the displacement-time graph at any instant gives the speed of the particle at that instant.
