Lukkehastighet
Lukkehastighet, or "terminal velocity," refers to the constant speed that an object reaches when the force of gravity pulling it downward is balanced by the upward force of air resistance, or drag. This concept is fundamental in physics and applies to various scenarios, including the motion of objects falling through a fluid, such as air or water.
When an object falls through the atmosphere, it initially accelerates due to gravity. As its speed increases,
In free-fall conditions, such as skydiving, terminal velocity for a human in a belly-to-earth position is approximately
Terminal velocity is also relevant in meteorology, where it describes the speed at which precipitation, like
The calculation of terminal velocity involves complex fluid dynamics, often requiring empirical data or computational models.
