Rev Up Your Brain: Unraveling the Name Associated with Speed

The term “Mach” is often associated with speed and refers to the measurement of an object’s velocity in relation to the speed of sound. This measurement was first introduced in the early 1900s by an Austrian physicist named Ernst Mach, who made significant contributions to the study of fluid dynamics and the science of shock waves. Today, the Mach number is commonly used in aviation and aerospace engineering to describe the performance of high-speed aircraft and spacecraft. The higher the Mach number, the greater the speed of the object in relation to the speed of sound.
