A non-inertial reference frame is a type of reference frame that is accelerating or rotating, meaning that it is not in a state of uniform motion. In a non-inertial frame, objects can behave in ways that are not consistent with Newton's laws of motion unless additional forces (called "fictitious" or "pseudo" forces) are taken into account.
