Kilometer/second
A kilometer per second (km/s) is a unit of speed representing the distance of one kilometer traveled in one second.
History/Origin
The kilometer per second has been used in scientific contexts, particularly in astronomy and physics, to measure high velocities such as the speed of celestial objects and spacecraft. Its usage became prominent with the development of precise measurement techniques in the 20th century.
Current Use
Today, km/s is primarily used in astronomy, astrophysics, and space science to describe the velocities of stars, galaxies, and spacecraft. It is also used in scientific research involving high-speed phenomena.
Cosmic Velocity - First
Cosmic velocity - first, also known as Earth's escape velocity, is the minimum speed needed for an object to escape Earth's gravitational influence without further propulsion.
History/Origin
The concept of escape velocity was developed in the early 20th century as part of classical mechanics and gravitational theory, with initial calculations by Sir Isaac Newton and later refinements through modern physics.
Current Use
It is used in aerospace engineering and astrophysics to determine the minimum speed required for spacecraft to leave Earth's orbit and travel into space without additional propulsion.
