On this graph, the x-axis represents time (t), and the y-axis represents velocity (v). The slope of the line at any given point illustrates the acceleration of an object at that point in time, while ...

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: ...

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 ...
