In relativistic dynamics one usually uses three-velocity or four velocity to describe instantaneous properties of timelike trajectories. The associated scalar quantity would be speed, the magnitude of the three-velocity. However, there are two other measures that have pleasing properties: celerity and rapidity. These quantities have associated functionality in the lorentz package which is shown here.
