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.
Foot/second
Foot per second (ft/s) is a unit of speed representing the distance of one foot traveled in one second.
History/Origin
The foot per second has been used historically in engineering, physics, and aeronautics, originating from the imperial measurement system where the foot is a standard unit of length. Its usage predates the metric system and has been common in the United States and other countries using imperial units.
Current Use
Today, ft/s is primarily used in fields such as physics, engineering, and aviation to measure speeds, especially in contexts where imperial units are standard. It is also used in sports and safety standards related to speed measurements.
