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.
Mile/hour
Mile per hour (mi/h) is a unit of speed representing the number of miles traveled in one hour.
History/Origin
The mile per hour has been used primarily in the United States and the United Kingdom for measuring speed, especially in transportation, since the adoption of the imperial system. Its usage dates back to the widespread use of miles as a distance measure before metric standardization.
Current Use
Today, mi/h is commonly used in the United States and some other countries to express vehicle speeds, speed limits, and other transportation-related velocities. It remains a standard unit in contexts where the imperial system is prevalent.
