Hi guys, can I say that since the sun orbits around the centre of mass of the solar system, it has angular momentum L=mvr. And since L=Iw, the sun itself will rotate about its own axis. Am I right to say that? However, conceptually speaking, is there a reason why the sun rotates? Also, what is the purpose of the direction of angular momentum? Is it just mainly used in conservation of angular momentum? I don't understand the real application of its direction. One very important qns when it comes to flywheel and angular momentum. I've searched for a video on YouTube and it says the angular momentum due to the torque of the weight of the fly wheel which makes it rotate vertically, is smaller than the angular momentum of the spinning flywheel, and hence it does not rotate like its dropping down that fast when it is spinning, which is what is called precession. Is this true? Why would a larger angular momentum take precedence in the overall motion? Isn't it the same as x-y 2D trajectory motion?? Thanks a lot people!!
