The Coriolis-only mode proves that only the Coriolis term with a minus sign can be an acceleration and the Coriolis force is defined, with the minus sign, exactly for the Newtonian analogy to work in this direction. This is why I start any explanation of the Coriolis force from the Coriolis term...

You wanted to know how the Coriolis-only motion could exist. I have just answered your question. Note that in physical studies, rotating systems are more frequently coherent, with centripetal forces, than not. The Coriolis-only mode aka "inertial oscillation mode" is then of huge importance.

The Coriolis force is the fictitious force associated to a very particular part of relative acceleration: -2 Ω x V with a minus sign. The positive acceleration with a plus sign called "Coriolis acceleration" is a tool for mathematics. I think it provides a good start. Because of the...

Am I wrong saying that the reference above highlights the Coriolis acceleration with a positive sign, like if it offered a better comprehension of the Coriolis effect? Here is the oscillation I am talking about: the inertial oscillation is an oscillating coupling between inertia and a...

The discourse about seeing the opposite of the Coriolis force as the effective acceleration is existing but unfortunately wrong. The Newtonian acceleration a=F/m derived from Newtonian force F is either disconnected from the rotating frame or connected to the rotation frame by the inertial...

Geometricians and rotating observers may appreciate the geometric significance of the Coriolis term but recall that the simple fact of rotating the frame of reference creates a complex term and not a Coriolis-only motion. You need a centripetal force for the Coriolis-only motion and the...

Actually the Corolis effect becomes a force when the inertia oscillation (or Coriolis-only motion) turns into a force instead of remaining a free process. This means that the centripetal force of the inertial frame of reference is also the resistance of the Coriolis-only motion facing adverse...

"It is clear that the conventionally available conceptual methods for teaching how the Coriolis force affects motion across the surface of the earth are too infrequent, inaccurate, or incomplete to construct the desired conceptual mastery." Jared Arnell, student of Boyd Edwards, 2022...
