Mitteinertsiaalsed

Mitteinertsiaalsed, also known as non-inertial frames of reference, are reference frames that are accelerating with respect to an inertial frame. Inertial frames are those in which Newton's laws of motion hold true, meaning that an object at rest stays at rest and an object in motion stays in motion at a constant velocity unless acted upon by an external force. In contrast, non-inertial frames experience fictitious forces, also known as inertial forces, which are not actually present in nature but are necessary to explain the observed motion within the accelerating frame.

Examples of non-inertial frames include rotating frames, such as a merry-go-round or the Earth's surface, and accelerating frames, such as a car that is speeding up or slowing down. In these frames, objects appear to be subject to forces that do not exist in inertial frames. For instance, on a merry-go-round, objects appear to move outward due to the centrifugal force, which is a fictitious force resulting from the rotation. Similarly, in an accelerating car, objects appear to move backward due to the inertia of the car, which is a fictitious force resulting from the acceleration.

The concept of non-inertial frames is crucial in understanding the behavior of objects in various reference frames and is widely used in fields such as physics, engineering, and astronomy. By recognizing and accounting for the fictitious forces, it is possible to accurately describe and predict the motion of objects in non-inertial frames.
