The Mach number is a measure of the ratio of the speed of an object to the speed of sound in the medium through which the object is traveling. It is used to describe how fast an object is moving compared to the speed of sound. For example, Mach 1 is the speed of sound, so a Mach number greater than 1 indicates supersonic speeds.
