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).

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.
Learn about different frames of reference (FOR) used in occupational therapy (OT) to guide practice and intervention. Each FOR has a theoretical basis, a focus, and a set of concepts that inform OT practice.

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.
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.
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.
