Rote :: Rote (v. i.) To go out by rotation or succession; to rotate.

Gyration :: Gyration (n.) The act of turning or whirling, as around a fixed center; a circular or spiral motion; motion about an axis; rotation; revolution..

Contrarotation :: Contrarotation (n.) Circular motion in a direction contrary to some other circular motion.

Paraboloid :: Paraboloid (n.) The solid generated by the rotation of a parabola about its axis; any surface of the second order whose sections by planes parallel to a given line are parabolas.

Glissette :: Glissette (n.) The locus described by any point attached to a curve that slips continuously on another fixed curve, the movable curve having no rotation at any instant..

Following :: Following (a.) (In the field of a telescope) In the direction from which stars are apparently moving (in consequence of the earth's rotation); as, a small star, north following or south following. In the direction toward which stars appear to move is called preceding..

Whirl :: Whirl (v. t.) A turning with rapidity or velocity; rapid rotation or circumvolution; quick gyration; rapid or confusing motion; as, the whirl of a top; the whirl of a wheel..

Gyroscope :: Gyroscope (n.) A form of the above apparatus, invented by M. Foucault, mounted so delicately as to render visible the rotation of the earth, through the tendency of the rotating wheel to preserve a constant plane of rotation, independently of the earth's motion..

Spina Bifida :: Spin (n.) Velocity of rotation about some specified axis.

Trochoid :: Trochoid (a.) Admitting of rotation on an axis; -- sometimes applied to a pivot joint like that between the atlas and axis in the vertebral column.

Orientation :: Orientation (n.) The tendency of a revolving body, when suspended in a certain way, to bring the axis of rotation into parallelism with the earth's axis..

Rotatory :: Rotatory (a.) Producing rotation of the plane of polarization; as, the rotatory power of bodies on light. See the Note under polarization..

Rotation :: Rotation (n.) The act of turning, as a wheel or a solid body on its axis, as distinguished from the progressive motion of a revolving round another body or a distant point; thus, the daily turning of the earth on its axis is a rotation; its annual motion round the sun is a revolution..

Irrotational :: Irrotational (a.) Not rotatory; passing from one point to another by a movement other than rotation; -- said of the movement of parts of a liquid or yielding mass.

Translation :: Translation (n.) Motion in which all the points of the moving body have at any instant the same velocity and direction of motion; -- opposed to rotation.

Revolution :: Revolution (n.) The act of revolving, or turning round on an axis or a center; the motion of a body round a fixed point or line; rotation; as, the revolution of a wheel, of a top, of the earth on its axis, etc..

Rolling :: Rolling (a.) Rotating on an axis, or moving along a surface by rotation; turning over and over as if on an axis or a pivot; as, a rolling wheel or ball..

Wabble :: Wabble (v. i.) To move staggeringly or unsteadily from one side to the other; to vacillate; to move the manner of a rotating disk when the axis of rotation is inclined to that of the disk; -- said of a turning or whirling body; as, a top wabbles; a buzz saw wabbles..

Operameter :: Operameter (n.) An instrument or machine for measuring work done, especially for ascertaining the number of rotations made by a machine or wheel in manufacturing cloth; a counter..

Cylinder :: Cylinder (n.) A solid body which may be generated by the rotation of a parallelogram round one its sides; or a body of rollerlike form, of which the longitudinal section is oblong, and the cross section is circular..
