==Equivalence of inertial reference frames==
A fundamental principle of ''all'' physics is the '''equivalence of inertial reference frame'''
By contrast, bodies are subject to so-called [[fictitious force]]s in [[non-inertial reference frame]]s; that is, [[force]]s that result from the acceleration of the [[reference frame]] itself and not from any physical force acting on the body. Examples of fictitious forces are the [[centrifugal force]] and the [[Coriolis force]] in [[rotating reference frame]]s. Therefore, scientists living inside a box that is being rotated or otherwise accelerated ''can'' measure their [[acceleration]] by observing the fictitious forces on bodies inside the box.
