## ve·loc·i·ty (v),

(vĕ-los'i-tē),
Rate of movement; specifically, distance traveled or quantity converted per unit time in a given direction. Compare: speed.
[L. velocitas, fr. velox (veloc-), quick, swift]

## velocity

[vəlos′itē]
Etymology: L, velox, quick
the rate of change in the position of a body moving in a particular direction. Velocity along a straight line is linear velocity. Angular velocity is that of a body in circular motion. Compare speed.

## velocity

An MRI term for the speed of a thing in a particular direction.

## velocity

The rate of a body's motion in a given direction per unit of time; speed Ballistics The speed that a projectile/bullet attains while in flight; the difference in tissue destruction between high- or low-velocity bullets is caused by the fragmentation of the bullet–as occurs in an M-16 semiautomatic weapon, rather than the speed of the bullet. See Ballistics, Critical velocity.

## ve·loc·i·ty

(v) (vĕ-los'i-tē)
Rate and direction of movement; specifically, distance traveled or quantity converted per unit time in a given direction.
[L. velocitas, fr. velox (veloc-), quick, swift]

## velocity

rate of change of position with respect to time. A vector quantity so has both magnitude (speed) and direction; linear velocity the linear displacement per unit time; angular velocity the angular displacement per unit time, i.e. speed of rotation in a particular direction (e.g. clockwise or anticlockwise); instantaneous velocity velocity of a body or object measured over a very short (infinitesimal) period of time: effectively a continuous measurement of velocity; tangential velocity the velocity of an object or body acting at a tangent to its direction of motion (often when it is moving in a circle or around a curve). See also displacement.

## velocity,

n rate of movement (speed) in a specific direction.

## ve·loc·i·ty

(vĕ-los'i-tē)
Rate and direction of movement.
