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 theoretical physics, a local reference frame (local frame) refers to a coordinate system or frame of reference that is only expected to function over...

inertial frame of reference (also called inertial space, or Galilean reference frame) is a stationary or uniformly moving frame of reference. Observed...

Instead, the notion of inertial frame of reference has taken precedence, that is, a preferred set of frames of reference that move uniformly with respect...
