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.
Yard/hour
Yard per hour (yd/h) is a unit of speed representing the distance of one yard traveled in one hour.
History/Origin
The yard has been a traditional unit of length in the imperial and US customary systems, and units like yard per hour have historically been used for measuring slow speeds, especially in contexts like textiles and manufacturing. Its usage has declined with the adoption of metric units.
Current Use
Yard per hour is rarely used today, primarily in specialized or historical contexts. It may still be referenced in certain industries or for conversions involving imperial units, but it is largely replaced by metric units such as meters per second or kilometers per hour.
