The acceleration of a vector always causes the ori
The acceleration of a vector always causes the orientation of the vector to change relative to any fixed inertial frame, as in a vector that follows an orbiting particle in parallel transport. That fact results in this phenomenon for that vector, which adds a factor of one half to the spin-orbit coupling in non-relativistic quantum mechanics.
