Inertial and Non-Inertial Frames
An inertial frame of reference is a reference frame that is not moving with respect to an observer. An inertial frame is a reference frame that is not accelerating with respect to an observer.
An inertial frame of reference is characterized by the following properties:
An observer in an inertial frame of reference measures the motion of objects in a constant direction.
An observer in an inertial frame of reference does not experience time dilation.
An observer in an inertial frame of reference does not experience length contraction.
A non-inertial frame of reference is a reference frame that is moving with respect to an observer. An observer in a non-inertial frame of reference measures the motion of objects in a changing direction.
The observer also experiences time dilation, length contraction, and other effects of special relativity.
The difference between an inertial and a non-inertial frame of reference is the observer's perspective. An observer in an inertial frame of reference will measure the motion of objects differently than an observer in a non-inertial frame of reference.
An inertial frame of reference is a reference frame in which the laws of physics are the same as those in a stationary frame of reference. An observer in an inertial frame of reference will measure the same physical phenomena, such as the motion of objects and the expansion of objects, as an observer in a stationary frame of reference
