In physics and astronomy, a frame of reference (or reference frame) is an abstract coordinate system whose origin, orientation, and scale are specified by a set of reference points ― geometric points whose position is identified both mathematically (with numerical coordinate values) and physically (signaled by conventional markers).

Let us first, however, briefly review Newton’s mechanics in terms of frames of reference. A “frame of reference” is just a set of coordinates: something you use to measure the things that matter in Newtonian problems, that is to say, positions and velocities, so we also need a clock.
Learn how to measure position and motion with respect to different frames of reference, such as Earth, a car, or space. Watch a video and see examples, definitions, and questions from learners.

Newtonian relativity: absolute linear motion at a constant velocity cannot be detected, nor can absolute rest. All motion is relative to a frame of reference. It is not possible to distinguish motion with a constant velocity from rest.
22 de sept. de 2004 · Each such choice is known as a frame of reference. Some possible frames are -- the interior of the airliner, -- the surface of the Earth, or -- the distant stars with respect to which the Earth rotates and moves. Choosing the Frame of Reference
