Centrifugal Force - Fictitious vs. Reactive Force

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)

    “Much is the force of heaven-bred poesy.”
    —William Shakespeare (1564–1616)
