In physics and astronomy, a frame of reference (or reference frame) is an abstract coordinate system, whose origin, orientation, and scale have been specified in physical space.

The meaning of FRAME OF REFERENCE is an arbitrary set of axes with reference to which the position or motion of something is described or physical laws are formulated.

To describe the position of a point that moves relative to a body that is moving relative to the Earth, it is usually convenient to use a reference frame attached to the moving body.

Jul 23, 2025 · Frame of reference is a way to observe and measure objects' positions and movements. It acts like a coordinate system, helping us understand where things are and how …

In physics, a frame of reference consists of an abstract coordinate system and the set of physical reference points that uniquely fix the coordinate system and standardize measurements within …

A frame of reference is a set of coordinates that can be used to determine positions and velocities of objects in that frame; different frames of reference move relative to one another.
