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.
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.
