The hypothetical graviton, while having a total angular momentum J = 2 would be massless and lack color charge, and so would be easily distinguished from glueballs.
42.
Since the three-dimensional rotator is rotating about an axis, the total angular momentum should be restricted in the same way as the two-dimensional rotator.
43.
It is not related to orbital motion, and moreover the total spin of a particle cannot change ( total angular momentum can be affected by external forces ).
44.
Now I suppose this is reversible-it could emit back out photons with the same total angular momentum-and so in a sense the momentum is conserved.
45.
Conservation of angular momentum is the principle that the total angular momentum of a system has a constant magnitude and direction if the system is subjected to no external torque.
46.
With three or more CMGs the situation can be immediately rectified simply by redistributing the existing total angular momentum among the rotors ( even if that total is zero ).
47.
If that's the case, then despite innumerable collisions and other interactions setting things spinning, the total angular momentum of the entire universe could still be zero.
48.
The total angular momentum ( quantum number " J " ) of a particle is therefore the combination of intrinsic angular momentum ( spin ) and orbital angular momentum.
49.
The Sun, for example, only accounts for about 0.3 percent of the total angular momentum of the Solar System while about 60 % is attributed to Jupiter.
50.
Note that the angular momentum "'L "'in this equation may be the spin angular momentum, the orbital angular momentum, or the total angular momentum.
