Kaluza-Klein theory suggests that all of them fictitious, though there is more consensus that the  centrifugal variety qualifies as such.
They are experienced between two plates in the Casimir effect, and one form is responsible for the breakdown of  nucleons into hadrons and leptons. Perturbation theory was applied to the effect of one of these to predict the orbits of the planets, while one class of them only allows for the inter-conversion of energy between its kinetic and  potential forms. Kaluza-Klein theory suggests that all of them fictitious, though there is more consensus that the  centrifugal variety qualifies as such. Occurring in tension, friction, and normal varieties as well as strong and weak forms is FTP, this concept in physics that causes acceleration, examples of which include gravity.
