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.
Mach (20°c, 1 Atm)
Mach is a unit of speed representing the ratio of an object's speed to the speed of sound in the surrounding medium, typically at 20°C and 1 atm pressure.
History/Origin
Named after physicist Ernst Mach, the Mach number was developed in the early 20th century to describe speeds relative to the speed of sound, especially in aeronautics and fluid dynamics.
Current Use
Mach is widely used in aeronautics and astronautics to express aircraft and spacecraft speeds, particularly in high-speed flight and supersonic travel contexts.
