Coriolis force
Coriolis forcen. A pseudo force used mathematically to describe motion, as of aircraft or cloud formations, relative to a noninertial, uniformly rotating frame of reference such as the earth.
[After Gaspard G. de Coriolis (1792-1843), French mathematician.]Coriolis force (ˌkɒrɪˈəʊlɪs) n (Astronomy) a fictitious force used to explain a deflection in the path of a body moving in latitude relative to the earth when observed from the earth. The deflection (Coriolis effect) is due to the earth's rotation and is to the east when the motion is towards a pole[C19: named after Gaspard G. Coriolis (1792–1843), French civil engineer]Coriolis forceThe tendency of the Earth’s rotation to turn winds and currents to the right in the northern hemisphere and to the left in the southern hemisphere.Thesaurus| Noun | 1. | Coriolis force - (physics) a force due to the earth's rotation; acts on a body in motion (airplane or projectile) in a rotating reference frame; in a rotating frame of reference Newton's second law of motion can be made to apply if in addition to the real forces acting on a body a Coriolis force and a centrifugal force are introducednatural philosophy, physics - the science of matter and energy and their interactions; "his favorite subject was physics"force - (physics) the influence that produces a change in a physical quantity; "force equals mass times acceleration" |
Coriolis force
Coriolis force (kor-ee-oh -liss, ko-ree-) A concept introduced to simplify calculations on the motion of bodies observed from a rotating frame of reference, such as the Earth. The effect of the Coriolis force is to deflect the object in a direction perpendicular to its course.Coriolis Force (named after the French scientist G. Coriolis), one of the inertia forces introduced to account for the effect of a rotating frame of reference on the relative motion of a material point. The Coriolis force is equal to the product of the mass of the point by its Coriolis acceleration and is directed opposite to this acceleration. The effect accounted for by the Coriolis force is such that in a rotating frame of reference a point moving not parallel to the axis of this rotation either is deflected in the direction perpendicular to its relative velocity or exerts pressure on the body obstructing such motion. On the earth, this effect is governed by the planet’s rotation and consists in the fact that a free-falling body is deflected from the vertical to the east (to the first approximation), while bodies moving along the earth’s surface in the direction of the meridian are deflected from their direction of motion to the right in the northern hemisphere and to the left in the southern hemisphere. These deflections are extremely small owing to the slow rotation of the earth and are noticeable only at great velocities of motion (as in the case of rockets or long-range artillery shells) or when the motion is of great duration (for example, the erosion of the corresponding river banks [seeBAER’S LAW] or the formation of certain air and sea currents). In engineering, Coriolis forces are taken into account in the theory of gyroscopes and turbines. S. M. TARG Coriolis force[kȯr·ē′ō·ləs ‚fȯrs] (mechanics) A velocity-dependent pseudoforce in a reference frame which is rotating with respect to an inertial reference frame; it is equal and opposite to the product of the mass of the particle on which the force acts and its Coriolis acceleration. Coriolis force In the Northern Hemisphere the Coriolis force deflects the winds toward right.An apparent force experienced by a body moving relative to the rotating earth. The wind blowing from the poles toward the equator turns to the right in the Northern Hemisphere and to the left in the Southern Hemisphere because of this Coriolis force, or Coriolis effect. Strictly, Coriolis force is a force that acts on a particle while it is moving along a path in a rotating plane.. Named after Gaspard Gustave de Coriolis (1792–1843).Coriolis force
