Climatology, Meteorology, Natural sciences, Physical sciences, Physics A fictitious force that acts on objects in motion within a frame of reference that rotates with respect to an inertial frame.
- 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.2006, J. Gordon Leishman, Principles of Helicopter Aerodynamics, page 197:
- 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.2013, C. H. Townes, A.L. Schawlow, Microwave Spectroscopy, page 30:
