Velocity-addition formula — In physics, a velocity addition formula is an equation that relates the velocities of moving objects in different reference frames. Contents 1 Galilean addition of velocities 2 Special theory of relativity 3 Derivation … Wikipedia
velocity — Rate of movement; specifically, distance traveled or quantity converted per unit time in a given direction. Cf.:speed. [L. velocitas, fr. velox (veloc ), quick, swift] initial v. the rate of a reaction, e.g., an enzyme catalyzed reaction, at the… … Medical dictionary
Group velocity — [ Frequency dispersion in bichromatic groups of gravity waves on the surface of deep water. The red dot moves with the phase velocity, and the green dots propagate with the group velocity. In this deep water case, the phase velocity is twice the… … Wikipedia
Critical ionization velocity — experiment onboard space shuttle Discovery (STS 39), releasing a plume of nitrous oxide gas. Full text Critical ionization velocity (CIV, also called Critical velocity, CV) is the relative v … Wikipedia
Space velocity — The space velocity of an astronomical object is its actual motion relative to the Sun or the Local standard of rest.AstrometryIts components in the Galactic coordinate system are usually designated U, V, and W, given in km/s, with U positive in… … Wikipedia
High-velocity star — A high velocity star is a star moving faster than 65 km/s to 100 km/s (definitions vary) relative to the average motion of the stars in the Sun s neighbourhood. The velocity is also sometimes defined as supersonic relative to the surrounding… … Wikipedia
High Accuracy Radial Velocity Planet Searcher — The High Accuracy Radial velocity Planet Searcher (HARPS) is a high precision echelle spectrograph installed in 2002 on ESO s 3.6m telescope at La Silla Observatory, with first light achieved February 2003. It is a second generation radial… … Wikipedia
Recessional velocity — is a term used to describe the rate at which an object is moving away, typically from Earth. Application to CosmologyThis term is generally only used in reference to distant Galaxies. The most common reason for the use of this term is Hubble s… … Wikipedia
Spacecraft Velocity Anomalies — refers to unexplained variances in the velocity of multiple spacecraft, where the spacecraft are traveling faster than expected or can so far be accounted for, relative to Earth orbit. Although the effect exists with spacecraft in orbits roughly… … Wikipedia
Dynamical friction — is a term in astrophysics related to loss of momentum and kinetic energy of moving bodies through a gravitational interaction with surrounding matter in space. It is sometimes referred to as gravitational drag, and was first discussed in detail… … Wikipedia
relativity — /rɛləˈtɪvəti / (say reluh tivuhtee) noun 1. the state or fact of being relative. 2. a. special theory of relativity, the theory formed by Albert Einstein of how the observed motion of objects changes from one frame of reference to another moving… …
