Mach (SI standard) Cosmic velocity - third

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.


Cosmic Velocity - Third

The third cosmic velocity is the minimum speed an object must reach to escape the gravitational pull of the Earth without further propulsion, approximately 11.2 km/s.

History/Origin

The concept of cosmic velocities was developed in the early 20th century to describe the different escape velocities from celestial bodies. The third cosmic velocity specifically relates to Earth's escape velocity, becoming prominent with advancements in astronautics and space exploration.

Current Use

The third cosmic velocity is used in space mission planning to determine the required speed for spacecraft to leave Earth's gravitational influence and reach interplanetary or interstellar space.
