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). [1]
Learn how to use frames of reference to describe the motion of objects in different coordinate systems. Explore examples of 1D and 2D frames of reference, collisions, energy changes and inertial frames.

A frame of reference is a theoretical model that integrates the two main domains of occupational therapy: occupation and adaptation. The web page explains the different types of frames of reference, such as compensatory, rehabilitative, biomechanical, psychoanalytic, developmental, behavioral, cognitive-behavioral, psychospiritual and occupational adaptation. Each type has its own key concepts and theoretical basis.
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. A point in space is specified by its three coordinates ( x , y , z ) and an “event” like, say, a little explosion, by a place and time: ( x , y ...
A reference frame is a like a fixed point. Properties of other objects such as: position, velocity etc. are measured using the point. It is so because no point in the universe is stationary or static. Every point is moving depending on another 'so called' static point.
Frames of reference where Newton's analysis works are called inertial frames. They are frames where the Principle of Inertia is true. For Newton, there was a "master" inertial frame: a frame stationary relative to absolute space.
