(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 introduced WordNet 3.0 & Open English WordNet

In physics, the Coriolis force is an inertial or fictitious force that acts on objects in motion within a frame of reference that rotates with respect to an inertial frame. Wikipedia

The apparent deflection of moving objects from a straight path when viewed from a rotating frame of reference Wikipedia Disambiguation

Apparent or fictitious force on objects moving within a reference frame that rotates with respect to an inertial frame Wikidata

A fictitious force apparently exerted on any moving body (including a parcel of air) due to the rotation of the earth, observed as a deflection of the body to the right of its direction of travel (i.e., clockwise) in the Northern Hemisphere, or to the left (anticlockwise) in the Southern Hemisphere; any equivalent apparent force that deflects objects in a rotating reference frame.
