Speed-time graphs show speed on the vertical axis and time on the horizontal axis. The gradient of a speed-time graph represents acceleration because: gradient = \( \frac {\text{change in y ...

The rate of change in the position of an object with respect to time and direction. In science, velocity is defined as the amount of displacement traveled by a body or an object at a given time ...
