A velocity-time (v-t) graph represents an object’s velocity (the rate of change in the object’s position) plotted against time. On this graph, the x-axis represents time (t), and the y-axis represents ...

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 ...

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 ...
