Bezugsraum
In physics, particularly in the fields of classical mechanics and relativity, the term *Bezugsraum* (German for "reference frame" or "frame of reference") refers to a coordinate system or perspective from which physical phenomena are observed and described. The concept is central to understanding motion, forces, and the laws governing the universe, as different reference frames can yield different descriptions of the same event.
A reference frame is defined by its position, orientation, and velocity relative to other objects or systems.
In the theory of relativity, developed by Albert Einstein, the distinction between reference frames becomes even
The choice of reference frame is often arbitrary but must be clearly specified when analyzing problems involving
