You don't need a physical linkage like that; it is enough to identify coordinate frames rotating relative to the inertial frame or to each other. To reconstruct an angular velocity from components, however, the components must actually be components of the angular velocity relative to a single set of ...

In relativistic physics, a velocity-addition formula is an equation that specifies how to combine the velocities of objects in a way that is consistent with the requirement that no object's speed can exceed the speed of light. Such formulas apply to successive Lorentz transformations, so they also relate different frames. Accompanying velocity addition is a kinematic effect known as Thoma… WebVelocity is a description of both speed and direction of motion. Velocity is a vector. How do velocities add?
