Centrifugal Force Calculator

About this calculator

This calculator finds the centrifugal force, F = m·v²/r (equivalently m·ω²·r using angular velocity), the outward-pointing pseudo-force felt by an object moving in a circular path when analyzed from the object's own rotating reference frame — the reaction, in effect, to the real inward centripetal force that keeps it turning. Mass m, speed v, and radius r determine its magnitude, with force growing with the square of speed and shrinking as the radius widens.

Mechanical engineers use this to design centrifuges that separate substances by density (blood samples, industrial slurries), engineers analyzing vehicle cornering use it to understand the forces passengers and cargo feel on a curve, and amusement-park ride designers use it to calculate the forces riders experience on spinning attractions. Physics students learning about rotating reference frames, lab technicians operating centrifuges, and appliance engineers designing washing-machine spin cycles all use this calculator regularly.
