Reference frames are used in many areas of science and technology to define the position, velocity, and acceleration of objects. In physics, reference frames are often used to describe the motion of particles, while in engineering and computer graphics, they are used to define the orientation of objects in 3D space. Some synonyms for reference frames include coordinate systems, spatial frames, and Euclidean frames. In astronomy, reference frames are used to measure the positions of stars and galaxies relative to each other. Other related terms include inertial frames, non-inertial frames, and rotating frames. Understanding reference frames is essential for many applications, from designing spacecraft to analyzing complex data sets.
