Displacement The distance travelled in a particular direction - it is a vector with magnitude and direction. Instantaneous Speed The rate of change of distance at a specific moment in time - change in distance divided by an infinitesimal interval of time. Average Speed The rate of change of distance calculated over a complete journey Velocity A vector quantity equal to the rate of change of displacement. Average Velocity The change in displacement (Δs) for a journey divided by the time taken (Δt).
