Kilometer/second
A kilometer per second (km/s) is a unit of speed representing the distance of one kilometer traveled in one second.
History/Origin
The kilometer per second has been used in scientific contexts, particularly in astronomy and physics, to measure high velocities such as the speed of celestial objects and spacecraft. Its usage became prominent with the development of precise measurement techniques in the 20th century.
Current Use
Today, km/s is primarily used in astronomy, astrophysics, and space science to describe the velocities of stars, galaxies, and spacecraft. It is also used in scientific research involving high-speed phenomena.
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.
