A fictitious force is a force that appears to act on a mass whose motion is described using a non-inertial frame of reference, such as a linearly accelerating or rotating reference frame. [1] Fictitious forces are invoked to maintain the validity and thus use of Newton's second law of motion, in frames of reference which are not inertial. [2]

For Polanyi, the effort by classical and neoclassical economics to make society subject to the free market was a utopian project and, as Polanyi scholars Fred Block and Margaret Somers claim, "When these public goods and social necessities (what Polanyi calls "fictitious commodities") are treated as if they are commodities produced for sale on the market, rather than protected rights, our ...
Fictitious capital (German: fiktives Kapital) is a concept used by Karl Marx in his critique of political economy. It is introduced in chapter 25 of the third volume of Capital . [ 1 ] Fictitious capital contrasts with what Marx calls "real capital", which is capital actually invested in physical means of production and workers, and "money ...
Common examples of this include the Coriolis force and the centrifugal force. In general, the expression for any fictitious force can be derived from the acceleration of the non-inertial frame. [ 6 ] As stated by Goodman and Warner, "One might say that F = m a holds in any coordinate system provided the term 'force' is redefined to include the ...
An example is an observational frame of reference centered at a point on the Earth's surface. This frame of reference orbits around the center of the Earth, which introduces the fictitious forces known as the Coriolis force, centrifugal force, and gravitational force. (All of these forces including gravity disappear in a truly inertial ...
This peculiarity of these forces led to the names inertial forces, pseudo-forces or fictitious forces. In particular, fictitious forces did not appear at all in some frames: those frames differing from that of the fixed stars by only a constant velocity. In short, a frame tied to the "fixed stars" is merely a member of the class of "inertial ...
Consequently, the fictitious force found above for this problem of rotating spheres is consistent with the general result and is not an ad hoc solution just "cooked up" to bring about agreement for this single example. Moreover, it is the Coriolis force that makes it possible for the fictitious force to change sign depending upon which of ω I ...
