Frame of reference

In physics, a frame of reference is a coordinate system used to specify either the position or the orientation or velocity of a body. The origin of the coordinate acts as a reference point for measuring the position or relative motion of a body. The coordinate system can be a cartesian coordinate, cylindrical coordinate, or a polar coordinate.
