I. (noun)
Sense 1
Meaning:
Distance travelled per unit time
Synonyms:
speed; velocity
Classified under:
Nouns denoting time and temporal relations
Hypernyms ("velocity" is a kind of...):
rate (a magnitude or frequency relative to a time unit)
Hyponyms (each of the following is a kind of "velocity"):
angular velocity ((physics) the rate of change of the angular position of a rotating body; usually expressed in radians per second or radians per minute)
airspeed (the speed of an aircraft relative to the air in which it is flying)
escape velocity (the minimum velocity needed to escape a gravitational field)
groundspeed (the speed of an aircraft relative to the ground)
hypervelocity (excessive velocity)
muzzle velocity (the velocity of a projectile as it leaves the muzzle of a gun)
peculiar velocity (velocity with respect to the local standard of rest)
radial velocity (velocity along the line of sight toward or away from the observer)
c; light speed; speed of light (the speed at which light travels in a vacuum; the constancy and universality of the speed of light is recognized by defining it to be exactly 299,792,458 meters per second)
steerageway ((nautical) the minimum rate of motion needed for a vessel to be maneuvered)
terminal velocity (the constant maximum velocity reached by a body falling through the atmosphere under the attraction of gravity)
