The most commonly encountered case of a moving frame is for the bundle of tangent frames (also called the frame bundle) of a manifold.In this case, a moving tangent frame on a manifold M consists of a collection of vector fields e 1, e 2, …, e n forming a basis of the tangent space at each point of an open set U ⊂ M.
Frame-dragging is an effect on spacetime, predicted by Albert Einstein's general theory of relativity, that is due to non-static stationary distributions of mass–energy. A stationary field is one that is in a steady state, but the masses causing that field may be non-static — rotating, for instance.
All frames of reference with zero acceleration are in a state of constant rectilinear motion (straight-line motion) with respect to one another. In such a frame, an object with zero net force acting on it, is perceived to move with a constant velocity, or, equivalently, Newton's first law of motion holds. Such frames are known as inertial.
From the local frame of reference of the blue clock, the red clock, being in motion, is measured as ticking slower. [9] Special relativity indicates that, for an observer in an inertial frame of reference, a clock that is moving relative to the observer will be measured to tick more slowly than a clock at rest in the observer's frame of ...
Although in a frame in which the interferometer is in motion, the transverse beam must traverse a longer, diagonal path with respect to the non-moving frame thus making its travel time longer, the factor by which the longitudinal beam would be delayed by taking times L/(c−v) and L/(c+v) for the forward and reverse trips respectively is even ...

One of the keys to maintaining screen direction is the 180-degree rule, which cuts a horizontal line through the frame. [3] Actors are then filmed from only one side of the axis, maintaining the orientation of the space for the viewer. [4] This can be manipulated specifically to create a shift in perspective.
