Remember, acceleration is the same as gradient, and acceleration = velocity change ÷ time. Look at the graph. The acceleration of the vehicle in the first 10 seconds is: ...

If we draw distance time graph for uniform motion then it will be straight line. ... Acceleration is non-zero. Distance-time graph. Here distance-time graph shows straight line.

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 ...
