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 on it. When the car is placed inside of it, it can be charged up and let loose at high speed. Later, "Mach Rider" was released as part of the "Nintendo Vs. Series" arcade variations. It was essentially a modified version of the Endurance Course from the original game. Each time the player completed a level, a bit more of an image was gradually revealed of a woman with a dagger appears next to Mach Rider's bike. While "Mach Rider" has not gained a true sequel, many elements from the game, such as the futuristic setting, incredible high speeds and
