Non-inertial reference frame - Wikipedia, the free encyclopedia
A non-inertial reference frame is a reference frame that is not an inertial reference frame. As such, the laws of physics in such a frame do not take on their most simple form, as required by the spe...

A frame of reference in physics, may refer to a coordinate system or set of axes within which to measure the position, orientation, and other properties of objects in it, or it may refer to an ob...

An inertial frame of reference has a constant velocity. That is, it is moving at a constant speed in a straight line, or it is standing still. Understand that when something is standing still, it has a constant velocity.

A non-inertial frame of reference does not have a constant velocity. It is accelerating. There are several ways to imagine this motion: ... Such an accelerating frame of reference is called a non-inertial frame because the law of inertia does not hold in it. That is, an object whose position is judged from this frame will...

So, although all frames of reference which are moving uniformly relative to an inertial reference frame are also inertial reference frames, all frames of reference which are moving non-uniformly (are accelerated) relative to an inertial reference frame are non-inertial reference frames.

The laws of Newtonian dynamics provide a simple definition: an inertial frame is a reference-frame with a time-scale, relative to which the motion of a body not subject to forces is always rectilinear and uniform, accelerations are always proportional to and in the direction of applied forces, and applied forces are...
