(of movement or activity) Characterized by great speed
his breathing was rapid and jerky
A fast-flowing and turbulent part of the course of a river
a part of a river where the current is very fast
done or occurring in a brief period of time; "a rapid rise through the ranks"
characterized by speed; moving with or capable of moving with high speed; "a rapid movement"; "a speedy car"; "a speedy errand boy"
(rapidly) quickly: with rapid movements; "he works quickly"
(rapidness) celerity: a rate that is rapid
A rapid is a section of a river where the river bed has a relatively steep gradient causing an increase in water velocity and turbulence. A rapid is a hydrological feature between a run (a smoothly flowing part of a stream) and a cascade. ...
RAPID is a high-level programming language used to control ABB industrial robots. RAPID was introduced along with S4 Control System in 1994 by ABB, superceeding the ARLA programming language.
In relativity, rapidity is an alternative to speed as a framework for measuring motion. On parallel velocities (say, in one-dimensional space) rapidities are simply additive, unlike speeds at relativistic velocities. ...
(RAPIDS) The Real-Time Automated Personnel Identification System (RAPIDS) is a United States Department of Defense (DoD) system used to issue the definitive credential within DoD. ...
a rough section of a river or stream which is difficult to navigate due to the swift and turbulent motion of the water; Describes a process or concept which occurs quickly
(rapidity) speed, swiftness; the condition of being rapid; A measure of velocity relative to the speed of light; A measure of the velocity of a particle in a beam relative to the beam#s axis
(rapidly) With speed; in a rapid manner
(rapidness) The characteristic of being rapid
(Rapidity (y)) Logarithmic ratio given by
(Rapids) A fast, turbulent stretch of whitewater normally accompanied by rocks and a steep gradient.
(Rapids) Section of a river where the currents speeds up and flows turbulently over and around boulders, drop-offs, ledges, etc. Also known as whitewater.
(Rapids) A part of a stream with considerable turbulence where the current is moving with much greater velocity than usual and where the water surface is broken by obstructions, but without a sufficient break in slope to form a cascade.
(Rapids) A fast and turbulent stretch of water which could include waves, haystacks, stoppers and drops. Rapids are graded 1 to 6 on the international scale.
(Rapids) An area of a river, stream, or course where the current is very rapid and flows around and over various obstacles.
(RAPIDS) A turbulent and swift-flowing section of a river. (rapides)
(RAPIDS) Any descent of a stream over a moderately steep slope in its stream bed. Characterized by swift moving water with violent choppy waves and whitewater. Also any vertical drop of less than five feet found along the course of a stream.
(RAPIDS) This term refers to a series of waves and turbulence.
(Rapids) An area of broken, fast flowing water in a stream, where the slope of the bed increases (but without a prominent break of slope which might result in a waterfall), or where a gently dipping bar of harder rock outcrops.
(Rapids) Fast-moving water that flows around rocks and boulders in rivers; classified from I to VI according to degree of difficulty navigating.
