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.
Velocity Of Light In Vacuum
The velocity of light in vacuum, denoted by the symbol c, is the constant speed at which electromagnetic waves propagate through empty space, approximately 299,792,458 meters per second.
History/Origin
The concept of the speed of light has been studied since the 17th century, with significant contributions from scientists like Ole Rømer, who first estimated its finite speed in 1676, and Albert Michelson, who refined measurements in the late 19th and early 20th centuries. The value of c was precisely defined in 1983 by the International System of Units (SI).
Current Use
The speed of light in vacuum is a fundamental constant used in physics, astronomy, and engineering. It underpins theories of relativity, defines the meter in the SI system, and is essential for calculations involving electromagnetic radiation and high-speed phenomena.
