Fictitious vs. Reactive Force
The table below compares various facets of the "fictitious force" and "reactive force" concepts of centrifugal force
| Fictitious centrifugal force | Reactive centrifugal force | |
|---|---|---|
| Reference frame |
Non-inertial frames | Any |
| Exerted by |
Acts as if emanating from the rotation axis, but no real source |
Bodies moving in curved paths |
| Exerted upon |
All bodies, moving or not; if moving, Coriolis force also is present |
The object(s) causing the curved motion, not upon the body in curved motion |
| Direction | Away from rotation axis, regardless of path of body |
Opposite to the centripetal force causing curved path |
| Analysis | Kinetic: included as force in Newton's laws of motion |
Kinematic: related to centripetal force |

Famous quotes containing the words fictitious and/or force:
“It is, indeed, at home that every man must be known by those who would make a just estimate either of his virtue or felicity; for smiles and embroidery are alike occasional, and the mind is often dressed for show in painted honour, and fictitious benevolence.”
—Samuel Johnson (1709–1784)
“Literary gentlemen, editors, and critics think that they know how to write, because they have studied grammar and rhetoric; but they are egregiously mistaken. The art of composition is as simple as the discharge of a bullet from a rifle, and its masterpieces imply an infinitely greater force behind them.”
—Henry David Thoreau (1817–1862)
