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.
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.
