The remark is correct. The example given in the first paragraph is a good illustration; the passengers experience a contact force from the backs of their seats pushing them in the forward direction, but that is not the fictitious force. The fictitious force is perceived to be pushing the passengers
1036:
A fictitious force (also called a pseudo force, d'Alembert force, or inertial force) is a force that appears to act on a mass whose motion is described using a non-inertial frame of reference, such as an accelerating or rotating reference frame. An example is seen in a passenger vehicle that is

snd modern term for these? In my experience âinertial forceâ or âpseudo-forceâ is far more common. These other terms are also more ventral where âfictitiousâ implies a level of fiction that isnât appropriate. They are apparent forces actually observed in non- inertial

accelerating in the forward direction â passengers perceive that they are acted upon by a force in the rearward direction pushing them back into their seats. An example in a rotating reference frame is the force that appears to push objects

From the map frame perspective, what is dangerous on losing centripetal acceleration may be speed. From the spin frame perspective, the danger instead may lie with the geometric acceleration which gives rise to that fictitious

I have a question about the map frame/spin frame animation which is under the "circular motion" paragraph.... I think it is brilliant and it shows the "fictional centrifugal force" beautifully.....but the text under it ?

Electromagnetic forces are not fictitious. They are body forces because they act on the whole of the body, including acting internally. Electromagnetic forces do not rely on contact at a point or over an area - see
