From Wikipedia, the free encyclopedia

A proper frame is a reference frame that is attached to an object. It is a frame that is sometimes described as comoving with the object. It has the effect of making the object seem stationary, which is useful for many types of calculations.

For example, a freely falling elevator is a proper frame for a free falling object in the elevator, while the surface of the Earth is not.

Proper frames can be inertial as well as non-inertial as in the example above.
