velocity bicycle wheels rims
Can the rotation of the Milky Way are compared with the rotation of a bicycle wheel?
In a bicycle wheel angular velocity is the same for each word or point on the rim. Is it true for the stars in the Milky Way? Are all stars with the same angular velocity?
The Milky Way is a spiral galaxy. When running at a speed not very uniform, say faster at the center and slower at the edges, you know what will happen? We will be stuck with a tightly wound spiral. However, we are stuck with a barred spiral. This is where the problem starts. In order to achieve this and to answer the question – the Milky Way has about the same angular velocity throughout. Remember there are exceptions and that the Milky Way is not a solid object, such as what is a bicycle wheel. It has no uniform mass distributions and the stars could be accelerated or slowed down as they cross the arms. This is especially true for the Sun, which was circulated by the poor. However, the average rate we will still be the same angular velocity. Same angular velocity is similar for most space stars. That includes the Sun, the stars in the spiral arms and all the stars in between. That is why the Milky Way is called to a rotation by 220-250 million years running. Now we The stars of the Galactic Bulge and halo. They travel in random motion which is not always in line with the plane of the Milky Way. Barnard star needs a good example. Their speed their jobs can be said that earlier. The latter are considered stars in the general vicinity of Sagittarius A *, that is our galactic core center. The stars to within one hundred light years this object traveling at a breakneck speed! Of course it is because of the local gravitational influence of the supermassive black hole is 4.1 million solar masses. The neasrest Sagittarius A * star S2 which is the closest distance to travel on mnster 5000km/sec! http://en.wikipedia.org/wiki/Spiral_galaxy http://en.wikipedia.org/wiki/Milky_Way http://stars.astro.illinois.edu/sow/barnard.html http://en.wikipedia .org/wiki/S2_ (star) http://www.newscientist.com/article/dn14749 Clear skies!
