Mach (Si Standard)
The Mach number is a dimensionless unit representing the ratio of an object's speed to the speed of sound in the surrounding medium.
History/Origin
Named after the Austrian physicist Ernst Mach, the Mach number was introduced in the early 20th century to describe supersonic and hypersonic speeds, initially used in aerodynamics and fluid dynamics research.
Current Use
The Mach number is widely used in aeronautics and astronautics to specify aircraft and spacecraft speeds relative to the local speed of sound, especially in high-speed flight regimes.
Earth's Velocity
Earth's velocity refers to the speed at which Earth moves through space, typically measured relative to the Sun or the cosmic microwave background.
History/Origin
The concept of Earth's velocity has been studied since the heliocentric model was proposed in the 16th century, with measurements improving through astronomical observations and modern satellite technology.
Current Use
Earth's velocity is used in astronomy, astrophysics, and space science to understand Earth's motion relative to other celestial bodies and the universe, often expressed in kilometers per second or miles per hour.
