2    the rate at which something moves, is done, or acts  
3      (Physics)  
a    a scalar measure of the rate of movement of a body expressed either as the distance travelled divided by the time taken (average speed) or the rate of change of position with respect to time at a particular point (instantaneous speed). It is measured in metres per second, miles per hour, etc.  
b       another word for       velocity       2

equivalent air speed  
      n   the speed at sea level that would produce the same Pitot-static tube reading as that measured at altitude  
film speed  
      n  
1    the sensitivity to light of a photographic film, specified in terms of the film's ISO rating  
2    the rate at which the film passes through a motion picture camera or projector  
group speed   , velocity  
      n     (Physics)   the speed at which energy is propagated in a wave. This is the quantity determined when one measures the distance which the radiation travels in a given time. In a medium in which the speed increases with wavelength the group speed is less than the phase speed, and vice versa  
high-speed  
      adj     (Photog)  
1    employing or requiring a very short exposure time

2    recording or making exposures at a rate usually exceeding 50 and up to several million frames per second  
3    working, moving, or operating at a high speed  
high-speed steel  
      n   any of various steels that retain their hardness at high temperatures and are thus suitable for making tools used on lathes and other high-speed machines  
landing speed  
      n   the minimum air speed at which an aircraft lands safely  
phase speed   , velocity  
      n     (Physics)   the speed at which the phase of a wave is propagated, the product of the frequency times the wavelength. This is the quantity that is determined by methods using interference. In a dispersive medium it differs from the group speed,   (Also called)    wave speed, wave velocity  
speed chess

! phi-speed (or φ-speed) n.
Materialistic concept neonewtonist. In its measures, this variation of length of traveled route (by unit of time) by a group of photons ( φ is the initial of photons) - the light signal - is equal to what is collectively called " radial velocity". It distinguishes itself from it in its gnoseology.
Phys. Concept before 2007 The redshift indicates the phi-speed of a star. But do not give the immediate knowledge of its absolute speed.
