Definitions

A fictitious force that acts on objects in motion within a frame of reference that rotates with respect to an inertial frame.

Examples

“On a rotor, Coriolis forces will appear⟳ whenever there is a radial lengthening or shortening of the blade about the rotational axis, which will be a result⟳ of blade flapping or bending.”

“These terms are generally thought of as due to Coriolis forces, and represent⟳ a coupling of the modes of vibration ω₂ and ω₃ Coriolis forces in the rotating molecule. The Coriolis force⟳ is a fictitious force⟳ which must be introduced if mechanical motion is studied in a rotating coordinate system and the rotation is otherwise overlooked.”

“First, we'll look⟳ at a simplified picture of how the pressure gradient and Coriolis forces affect⟳ an air parcel high above the ground.”
