Mach number Mach number In fluid dynamics, the Mach number (M or Ma) (; ) is a dimensionless quantity representing the ratio of flow velocity past a boundary to the local speed of sound. where: By definition, at Mach1, the local flow velocity is equal to the speed of sound. At Mach0.65, is 65% of the speed of sound (subsonic), and, at Mach1.35, is 35% faster than the speed of sound (supersonic). The local speed of sound, and thereby the Mach number, depends on the condition of the surrounding medium, in particular the temperature. The Mach number is primarily used to determine
Mach Rider against a hazard on the track, they obtain more points— this also replenishes Mach Rider's bullets. "Mach Rider" takes place in the year 2112, and planet Earth has been invaded by evil forces driving vehicles known as Quadrunners. The player controls Mach Rider, who travels from sector to sector on a high-powered superbike, searching for survivors and destroying any enemies in their path. In 1972, "Mach Rider" was originally released as a plastic race car or hot rod toy also by Nintendo that came with a ramp for jumping and a stick shift-like object with three different kinds of meters
