1. Instead of boosts, it features shear mappings to relate co-moving frames of reference. 2. As already shown above, these forces have the form in a non-co-moving frame : 3. A manifold that does have a global moving frame is called " parallelizable ". 4. Three other parameters define the orientation of the moving frame relative to the fixed frame. 5. It can be constructed by applying a transformation to the moving frame of a general helix. 6. The stationary coordinates of the observer relate to the moving frame of the charge as follows 7. But we know that time goes slower in moving frame , so we always have t'\ sec. 8. The speed of light is considered to be the only true constant between moving frames of reference. 9. Intrinsically a moving frame can be defined on a principal bundle " P " over a manifold. 10. In fact, in the method of moving frames , one more often works with coframes rather than frames.
