A rotating frame of reference is a special case of a non-inertial reference frame that is rotating relative to an inertial reference frame. An everyday example of a rotating reference frame is the surface of the Earth. (This article considers only frames rotating about a fixed axis. For more general rotations, see Euler angles.)
X4: Foundations is a space trading and combat game developed and published by Egosoft. It is the seventh and most recent installment in the X series, following X Rebirth ( 2013 ). The game runs on Linux and Microsoft Windows .
Four full sequels have since followed: X2: The Threat in 2003, X3: Reunion in 2005, X3: Terran Conflict in 2008, and X4: Foundations in 2018. X: Beyond the Frontier and X-Tension were released together as X-Gold in 2000. A novel, Farnham's Legend, is based on the plot of X: Beyond the Frontier.
Bouncing ball in a rotating space station: The objective reality of the ball bouncing off the outer hull is confirmed both by a rotating and by a non-rotating observer, hence the rotation of the space station is an "absolute", objective fact regardless of the chosen frame of reference.
For any inertial frame, the Coriolis force and the centrifugal force disappear, so application of the principle of special relativity would identify these frames where the forces disappear as sharing the same and the simplest physical laws, and hence rule that the rotating frame is not an inertial frame.
Earth-centered inertial (ECI) coordinate frames have their origins at the center of mass of Earth and are fixed with respect to the stars. [1] " I" in "ECI" stands for inertial (i.e. "not accelerating "), in contrast to the "Earth-centered – Earth-fixed" ( ECEF ) frames, which remains fixed with respect to Earth's surface in its rotation ...
One may instead change to a coordinate frame fixed in the rotating body, in which the moment of inertia tensor is constant. Using a reference frame such as that at the center of mass, the frame's position drops out of the equations. In any rotating reference frame, the time derivative must be replaced so that the equation becomes
Some properties of Kottler-Møller or Rindler coordinates were anticipated by Albert Einstein (1907) [H 1] when he discussed the uniformly accelerated reference frame. While introducing the concept of Born rigidity, Max Born (1909) [H 2] recognized that the formulas for the worldline of hyperbolic motion can be reinterpreted as transformations into a "hyperbolically accelerated reference system".
