A graph of these data looks like this. The blue circles are the points we measured and the light-blue line is the probable position vs. time function which varies smoothly as it passes through the ...

A negative gradient shows the rate of “slowing down” or deceleration. Velocity-time graphs show velocity on the vertical axis. Acceleration is still represented by the gradient. Key fact The ...

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.
