-
noun (physics) the rate of change of the angular position of a rotating body; usually expressed in radians per second or radians per minute
WordNet
- the ratio of anuglar motion to the time employed in describing.
Webster 1913
escape velocity
-
noun the minimum velocity needed to escape a gravitational field
WordNet
high-velocity
-
adjective satellite operating at high speed
high-speed.
- a high-speed food processor
- a high-velocity shell
WordNet
Initial velocity
- the velocity of a moving body at starting; especially, the velocity of a projectile as it leaves the mouth of a firearm from which it is discharged.
Webster 1913
muzzle velocity
-
noun the velocity of a projectile as it leaves the muzzle of a gun
WordNet
Paracentric motton ∨ velocity
- the motion or velocity of a revolving body, as a planet, by which it approaches to, or recedes from, the center, without reference to its motion in space, or to its motion as reckoned in any other direction.
Webster 1913
Parallelogram of velocities , forces , accelerations , momenta , etc.
(Mech.) , a parallelogram the diagonal of which represents the resultant of two velocities, forces, accelerations, momenta, etc., both in quantity and direction, when the velocities, forces, accelerations, momenta, etc., are represented in quantity and direction by the two adjacent sides of the parallelogram.
Webster 1913
peculiar velocity
-
noun velocity with respect to the local standard of rest
WordNet
Principle of virtual velocities
(Mech.) , the law that when several forces are in equilibrium, the algebraic sum of their virtual moments is equal to zero.
Webster 1913
radial velocity
-
noun velocity along the line of sight toward or away from the observer
WordNet
Relative velocity
- the velocity with which a body approaches or recedes from another body, whether both are moving or only one.
Webster 1913
Terminal velocity
-
noun the constant maximum velocity reached by a body falling through the atmosphere under the attraction of gravity
WordNet
- .
(a) The velocity acquired at the end of a body's motion.(b) The limit toward which the velocity of a body approaches, as of a body falling through the air.
Webster 1913
Uniform velocity
- velocity in which the same number of units of space are described in each successive unit of time.
Webster 1913
Variable velocity
- velocity in which the space described varies from instant, either increasing or decreasing; in the former case called accelerated velocity, in the latter, retarded velocity; the acceleration or retardation itself being also either uniform or variable.
Webster 1913
Virtual velocity
(Mech.) , a minute hypothetical displacement, assumed in analysis to facilitate the investigation of statical problems. With respect to any given force of a number of forces holding a material system in equilibrium, it is the projection, upon the direction of the force, of a line joining its point of application with a new position of that point indefinitely near to the first, to which the point is conceived to have been moved, without disturbing the equilibrium of the system, or the connections of its parts with each other. Strictly speaking, it is not a velocity but a length.
