Second, the z-component of angular momentum is negative. This means the angular momentum vector is pointing in a direction that would appear to be into the screen (from your view).

They managed to generate and control high-order vector vortex ... under the coordinated control of spin-orbit angular momentum ... e-mail message and is not retained by Phys.org in any form.

Now that the cars are moving, the angular momentum would be: Angular momentum is conserved. This means that L 0 = L 2. I want to solve for the change in angular velocity. To do this, I will set ...
