conservation of angular momentum

[‚kän·sər′vā·shən əv ′aŋ·gyə·lər mə′men·təm]
(mechanics)
The principle that, when a physical system is subject only to internal forces that bodies in the system exert on each other, the total angular momentum of the system remains constant, provided that both spin and orbital angular momentum are taken into account.

Far more important is the conservation of angular momentum under the influence of the Coriolis Effect.
This perfect anticorrelation reflects conservation of angular momentum, which in turn emerges from rotational invariance.
This movement, brought about by the conservation of angular momentum, adds to the time required to focus antennas on an object.
At present, the best guess for the cause of the particle outflows is related to the conservation laws, Evans notes - in this case, the conservation of angular momentum. Because the matter falling in wards tends to spin faster, astrophysicists think that a newly forming star propably will sling off some of its mass.
The default in planet formation is for worlds to coalesce from a dusty disk of gas around a newborn star's middle, a consequence of the conservation of angular momentum. Furthermore, huge planets close to their parent stars "should" be on circular, equator-aligned orbits due to tidal interactions.
It turns it's actually due to the conservation of angular momentum.
In addition, in the areas such as physics, mechanics, engineering and so on, there are three very important laws: the law of conservation of energy, the law of conservation of momentum and the law of conservation of angular momentum. If we believe that the law of conservation of energy is the truth, then for the law of conservation of momentum and the law of conservation of angular momentum, either they can be derived by the law of conservation of energy, or we can prove that in certain cases they are not true.
Conservation of angular momentum is a fundamental property of nature, one that astronomers use to detect the presence of satellites circling distant planets.
The conservation of energy (12) follows again, while for the conservation of angular momentum we find
Conservation of angular momentum dictates that if the star was rotating, the resulting black hole should rotate even faster.
As different as these objects are, they all take their shape for the same reason: conservation of angular momentum in a rotating system of stuff that can't get rid of it.
It's actually down to the conservation of angular momentum.
