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 (17091784)
“What I am anxious to do is to get the best bill possible with the least amount of friction.... I wish to avoid [splitting our party]. I shall do all in my power to retain the corporation tax as it is now and also force a reduction of the [tariff] schedules. It is only when all other efforts fail that Ill resort to headlines and force the people into this fight.”
—William Howard Taft (18571930)
