Coriolis Force
Version 1.0.0 · Updated 2026-07-28
CORE DEFINITION
Describing motion in a frame rotating relative to an inertial frame introduces the Coriolis term F = −2mΩ×v, where v is velocity relative to the rotating frame. It is an inertial force arising from the frame transformation, not an additional physical interaction. Deflection observed relative to the rotating frame is measurable.
SCAFFOLDING EFFECT
Reduce cognitive load
Specify the reference frame for velocity and include inertial terms correctly when analyzing motion in rotating frames. Organizational or market analogies about environmental bias require independent evidence; they do not follow from this physical law.
Anchor fast decisions
Transforming time derivatives of position between inertial and rotating frames introduces a velocity-dependent term proportional to Ω×v. The horizontal deflection of horizontal motion near Earth’s surface is rightward in the Northern Hemisphere and leftward in the Southern Hemisphere. The usual zero-at-the-equator statement concerns this horizontal component, not the full Coriolis force for every motion.
