The gradient or the steepness of the graph can be used to work out the acceleration ... 1700 m. Average speed = total distance ÷ total time = 1,700 m ÷ 50 s = 34 m/s. Look at this velocity ...
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.
