Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating ...

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.

how far does it travel during some time interval? Let's start with the definition of velocity (in one dimension): But what if I represent this as a graph? Here is a velocity vs time graph for this ...
