Although we might regret the speed at which the years appear to ... So maybe we don’t really want time to go more slowly after all. To make time go faster if you are waiting in queue, reframe ...

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.
