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 ...

Velocity-time graphs show velocity on the vertical axis. Acceleration is still represented by the gradient. Key fact. The gradient of speed-time and velocity-time graphs represent acceleration.
