velocity — /veuh los i tee/, n., pl. velocities. 1. rapidity of motion or operation; swiftness; speed: a high wind velocity. 2. Mech. the time rate of change of position of a body in a specified direction. 3. the rate of speed with which something happens;… … Universalium
Velocity — In physics, velocity is defined as the rate of change of position. It is a vector physical quantity; both speed and direction are required to define it. In the SI (metric) system, it is measured in meters per second: (m/s) or ms 1. The scalar… … Wikipedia
Velocity obstacle — The velocity obstacle VOAB for a robot A, with position xA, induced by another robot B, with position xB and velocity vB. In robotics and motion planning, a velocity obstacle, commonly abbreviated VO, is the set of all velocities of a robot … Wikipedia
QT interval — Schematic representation of normal ECG trace (sinus rhythm), with waves, segments, and intervals labeled. In cardiology, the QT interval is a measure of the time between the start of the Q wave and the end of the T wave in the heart s electrical… … Wikipedia
Four-velocity — In physics, in particular in special relativity and general relativity, the four velocity of an object is a four vector (vector in four dimensional spacetime) that replaces classical velocity (a three dimensional vector). It is chosen in such a… … Wikipedia
Lorentz interval — The Lorentz interval is a quantity that is used instead of distance when dealing with space time geometry, because it is the only quantity that is the same to all observers regardless of how fast they are moving in spacetime, that is, in all… … Wikipedia
