We typically measure deceleration in meters per second squared (m/s²) or feet per second squared (ft/s²). Calculating Deceleration. To calculate deceleration, you need two key pieces of information: ...

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 ...

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 ...

Speed-time graphs show speed on the vertical axis and time on the horizontal axis. The gradient close gradient In a graph, the gradient is the steepness of the line.
