Velocity-time graphs show how the velocity (or speed ... means that the vehicle is accelerating at an increasing rate – non-uniform acceleration. A line upwards curving to become flat means ...

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 ...

Oh, and this video has a frame rate of 50,000 frames per second ... The slope of the velocity-time graph is the average acceleration. You can see the fitting equation gives an average acceleration ...

Of course I can also get time data by assuming the video frame rate is legitimate ... the slope of a velocity-time graph will be the acceleration of the car. Notice that I have fit four linear ...
