Acceleration = change of velocity ÷ time taken. is the rate of change of velocity. It is the amount that velocity changes per unit time. The change in velocity can be calculated using the ...

or \(= {ms}^{-2}\). 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.

Different types of velocity are explored, and we investigate how to find information from a position versus time graph.

Editor's Note: The Hyperloop is a totally imaginary transportation device that has captivated entrepreneur Elon Musk, who keeps talking about it. First imagined at least 100 years ago, it would ...

See if you can create the same (or at least very similar) position vs. time graph for the car based on just the velocity data (and not the acceleration). Here's a hint to get you started ...
