and so is a vector quantity. Average velocity = \(\frac{\text{displacement}}{\text{time}}\) Displacement is the distance moved in a straight line, in a given direction, from the starting point.

Displacement ... Velocity is a speed and a direction, eg \(12 m\,s^{-1}\) on bearing 055 (55º East of North). The term acceleration can refer to a scalar acceleration or an acceleration vector.

Kinematic sensing for displacement and velocity vectors is in high demand in manufacturing, transportation, robotics, mapping and so on. Current technologies for these vector measurements are ...
