Kilometer per Second

km/s

Definition

The kilometer per second is a unit of speed representing the distance of one kilometer traveled in one second. It is used for measuring extremely high speeds such as those of spacecraft, projectiles, or other high-velocity objects in physics and engineering.

History/Origin

Kilometer per second was developed for measuring extremely high velocities in physics, astronomy, and aerospace engineering. It became essential for expressing speeds of spacecraft, satellites, and other high-velocity objects in space exploration.

Current Use

Kilometer per second is used in aerospace engineering for spacecraft velocities, in physics for high-speed particle studies, in astronomy for celestial object speeds, and in military applications for projectile velocities.

Mach (20°C, 1 atm)

Ma

Definition

Mach at 20°C and 1 atmosphere is the speed of sound in air under these specific conditions, approximately 343.6 meters per second. It is used as a reference for measuring high speeds, particularly in aviation and aerospace applications.

History/Origin

The Mach number was named after Austrian physicist Ernst Mach and became the standard for measuring high speeds in aviation. It represents the ratio of an object's speed to the speed of sound in the surrounding medium.

Current Use

Mach is used in aviation for measuring aircraft speeds, in aerospace engineering for high-speed vehicle design, and in various applications involving high-speed motion. It is particularly important for supersonic and hypersonic flight.
