SPEED
Qualified
Was 'velocity' but is renamed 'speed' as the definition only states the rate of change, but there is no mention of the direction of change in the position of an object. This class therefore defines the scalar absolute value (magnitude) of velocity, which is speed.|Subclasses needs to be remodelled.
