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.
Kilometer/hour
Kilometer per hour (km/h) is a unit of speed expressing the number of kilometers traveled in one hour.
History/Origin
The km/h unit originated from the metric system, developed in France during the late 18th century, and became widely adopted for measuring speed in transportation and scientific contexts.
Current Use
Km/h is commonly used worldwide to specify vehicle speeds, speed limits, and other applications involving the measurement of speed in everyday life and transportation systems.
