An inertial reference frame is a coordinate system in which Newton's first and second laws of motion are valid. In particular, a body viewed from an inertial frame accelerates only when a physical force is applied; in the absence of a net force, a body at rest remains at rest and a body in motion continues to move uniformly, i.e., in a straight line at constant speed (Newton's first law of motion).
Equivalence of inertial reference frames
A fundamental principle of all physics is the equivalence of inertial reference frames. In practical terms, this equivalence means that scientists living inside an enclosed box moving uniformly cannot detect their motion by any experiment done exclusively inside the box.
By contrast, bodies are subject to so-called fictitious forces in non-inertial reference frames; that is, forces 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 frames. 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.
