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.
Knot
A knot is a unit of speed equal to one nautical mile per hour, commonly used in maritime and aviation contexts.
History/Origin
The knot originated from the practice of measuring a ship's speed using a device called a chip log, which involved counting the number of knots that passed through a sailor's hands over a specific time interval. It became standardized as a unit of speed in maritime navigation.
Current Use
Today, the knot is primarily used in maritime and aviation industries to express the speed of ships and aircraft, providing a consistent measurement across international waters and airspace.
