Unreferenced stub auto yes date December 2009 Recessional velocity is a term used to describe the rate at which an object is moving away, typically from Earth . Application to cosmology This term is generally only used in reference to distant Galaxy galaxies . The most common reason for the use of this term is Hubble law Hubble s Law , which states that the redshift is proportional to the distance between an inertial Observation observer and a distant galaxy . The redshift is usually interpreted as due to recessional velocity which can be calculated according to the formula math v H 0 D math where math H 0 math is the Hubble constant , math D math is the intervening distance, and math v math is the recessional velocity , generally measured in km s. The recessional velocity of a galaxy is usually calculated from the redshift observed in its emitted electromagnetic radiation . The distance to the galaxy is then estimated using Hubble s Law .

No footnotes date April 2009 The signal velocity is the speed at which a wave carries information. It describes how quickly a message can be communicated using any particular method between two separated parties. Every signal velocity is always slower than or equal to the speed of a light pulse in a vacuum by Special Relativity . Signal velocity is usually equal to group velocity the speed of a short pulse or of a wave packet s middle or envelope . However, in a few special cases e.g., media designed to amplify the front most parts of a pulse and then attenuate the back section of the pulse , group velocity can exceed the speed of light in vacuum, while the signal velocity will still be less than or equal to the speed of light in vacuum. In electronic circuits, signal velocity is one member of a group of five closely related parameters. In these circuits, signals are usually treated as operating in Transverse mode TEM Transverse ElectroMagnetic mode. That is, the fields are perpendicular to the direction of transmission and perpendicular to each other. Given this presumption, the quantities signal velocity, the product of dielectric constant and magnetic permeability, characteristic impedance, inductance of a structure, and capacitance of that structure, are all related such that if you know any two, you can calculate the rest. In a uniform medium if the permeability is constant, then variation of the signal velocity will be dependent only on variation of the dielectric constant. In a transmission line, signal velocity is the reciprocal of the square root of the capacitance ... boards made of FR4 material, the signal velocity is typically about six inches 15 cm per nanosecond ... location to location, causing variations in signal velocity.

Classical mechanics In non relativistic kinematics , relative velocity is the vector geometric vector vector geometric Addition and scalar multiplication difference between the Velocity velocities of two objects, as evaluated in terms of a single coordinate system . For example, if the velocities of particles A and B are math mathbf v A math and math mathbf v B math respectively in terms of a given coordinate system, then the relative velocity of A with respect to B also called the velocity of A relative to B, math mathbf v A B math , or math mathbf v A mathrm rel B math is math mathbf v A mathrm rel B mathbf v A mathbf v B math . The expression the velocity of A relative to B is shorthand for the velocity of A in the coordinate system where B is always at rest . Conversely, the velocity of B relative to A is math mathbf v B mathrm rel A mathbf v B mathbf v A math . To be clear, the velocity of B as seen from A which is to say, math mathbf v B mathbf v A math is another expression meaning the velocity of B relative to A or indeed the velocity of B in the coordinate system where A is considered at rest Example Joe and Sara are driving in the same direction. Joe s velocity is 90 km h and Sara s 100 km h. If we take Joe s velocity as math mathbf v B math and Sara s math mathbf v A math then math mathbf v A mathrm rel B 100 90 10 text km h. math This is the velocity observed by Joe.

Velocity was a free, weekly magazine published between December 3, 2003 and June 15, 2011, by The Courier Journal of Louisville, Kentucky Louisville , Kentucky . The full color tabloid was distributed at 1,800 locations in a 13 county area in Kentucky and Southern Indiana . Velocity was widely seen as an attempt by the Courier Journal and its parent company, Gannett , to gain some of the market dominated by the Louisville Eccentric Observer , an alternative newsweekly. Velocity targeted the 25 to 34 year old age demographic. It was consciously non political, although it occasionally covered hot button issues such as the Iraq War, local and national elections, the ban on public smoking in Louisville and gay life. Regular weekly features included The Bar Hopper, in which a local tavern was profiled The Party Crasher, a photo story from the weekend s parties and What I m Into, a mini profile of a local person.

As the applied electric field increases from that point, the carrier velocity no longer increases because the carriers lose energy through increased levels of interaction with the lattice, by emitting phonons and even photon s as soon as the carrier energy is large enough to do so. ref name co cite web url http ece www.colorado.edu bart book book chapter7 ch7 7.htm 7 7 7 title Advanced MOSFET issues accessdate 2006 10 23 ref Design considerations When designing semiconductor device s, especially on a sub micrometre scale as used in modern microprocessor s, velocity saturation is an important design characteristic. Velocity saturation greatly affects the voltage transfer characteristics of a field effect transistor , which is the basic device used in most integrated circuits designed and produced in the world. If a semiconductor device enters velocity saturation, an increase in voltage applied to the device will not cause a linear increase in current as would be expected by Ohm s law . Instead, the current may only increase by a small amount, or not at all. It is possible to take advantage of this result when trying to design a device that will pass a constant current regardless of the voltage applied, a current limiter in effect.

The drift velocity is the average velocity that a particle, such as an electron , attains due to an electric field . It can also be referred to as Axial Drift Velocity since particles defined are assumed to be moving along a plane. In general, an electron will rattle around in a Electrical conductor conductor at the Fermi energy Fermi velocity randomly. An applied electric field will give this random motion a small net velocity in one direction. In a semiconductor , the two main carrier scattering mechanisms are ionized impurity scattering and lattice scattering . Because current is proportional to drift velocity, which is, in turn, proportional to the magnitude of an external electric field, Ohm s law can be explained in terms of drift velocity. Drift velocity is expressed in the following equations math J it drift rho cdot v it avg math , where math J it drift math is the current density, math rho math is charge density in units Coulomb C m sup 3 sup , and v sub avg sub is the average velocity of the carriers drift velocity math v it avg mu cdot E math , where is the electron mobility in m 2 V.s and E is the electric field in volt V m.

Saturation velocity is the maximum velocity a charge carrier in a semiconductor , generally an electron , attains in the presence of very high electric field s ref Fundamentals of Semiconductors Physics and Materials Properties , Peter Y. Yu, Manuel Cardona, pp.227 228, Springer, New York 2005, ISBN 3 540 25470 6 ref . Charge carrier s normally move at an average drift speed proportional to the electric field strength they experience temporally. The proportionality constant is known as Electrical mobility mobility of the carrier, which is a material property. A good Electrical conductor conductor would have a high mobility value for its charge carrier, which means higher velocity, and consequently higher current values for a given electric field strength. There is a limit though to this process and at some high field value, a charge carrier can not move any faster, having reached its saturation velocity, due to mechanisms that eventually limit the movement of the carriers in the material ... 5 ref .

It was directed by Ernie Gehr and filmed in the basement hallway of a Binghamton University academic building. To make the film, Gehr locked his camera down in the center of the hallway, shooting several individual frames at a time. After each set of exposures, he changed the focal length on the lens, zooming in and then out in increasing increments. What begins as a small difference in apparent distance several frames at a time expands to extreme closeups and wide shots jumping back and forth. The film runs about twenty three minutes long and is silent. In 2001, the United States Library of Congress deemed the film culturally significant and named it to the National Film Registry .

Velocity Games is an internationally recognized action sports event founded in Texas in 2003 and considered the most publicized windsports event in the nation, by Kiteatlas.com. The five day event is held annually on Memorial Day Weekend in Corpus Christi, Texas , the Windsurfing Capital of the contiguous United States. Corpus Christi, Texas sits along Corpus Christi Bay in the Gulf of Mexico. The Velocity Games was originally created as a vehicle for the U.S. Open Windsurfing Regatta and the U.S. Open Kiteboarding Championships. Although the events are recognized worldwide and covered by the major windsports magazines, they typically attracted a viewing audience of less than 5,000 spectators. In the first year under the Velocity Games umbrella, the events attracted more than 50,000 spectators, according to the Corpus Christi Caller Times . The Velocity Games event was almost cancelled before it began when one of its co founders, Peter Nordby , was killed in a kiteboarding accident six months before the event was set to launch in May 2003. The organizers put the event planning on hold, but due to the urging of the windsurfing and kiteboarding communities, the planning resumed in time for its scheduled Memorial Day Weekend opening date.

Explosive velocity , also known as detonation velocity or velocity of detonation VoD , is the velocity at which the shock wave front travels through a detonation detonated explosive . The data listed for a specific substance is usually a rough prediction based upon Gas laws gas behavior theory Citation needed date December 2008 see Chapman Jouguet condition , as in practice it is difficult to measure Citation needed date December 2008 . Explosive velocities are always faster than the local speed of sound in the material. If the explosive is confined before detonation, such as in an artillery shell, the force produced is focused on a much smaller area, and the pressure is massively intensified. This results in explosive velocity that is higher than if the explosive had been detonated in open air. Unconfined velocities are often approximately 70 to 80 percent of confined velocities. ref name GlobalSecurity.org http www.globalsecurity.org military systems munitions explosives.htm GlobalSecurity.org ref Explosive velocity is increased with smaller particle size i.e. increased spatial density , increased charge diameter, and increased confinement i.e. higher pressure . ref name GlobalSecurity.org Typical Table of explosive detonation velocities detonation velocities in gases range from 1800 Metre per second m s to 3000 m s.
