We believe that our galaxy was formed from a huge cloud of gas. The original cloud was far larger than the present size of the galaxy, was more or less spherical, and was rotating very much more slowly than the galaxy is now. In this sketch, we see the original cloud and the galaxy as it is now (seen edgewise). Explain how the law of gravitation and the conservation of angular momentum contribute to the galaxy's present shape and why it rotates faster now than when it was a larger, spherical cloud.

Different masess move differently.

Explanation:

When the line of gravity is within the buissness operating system, an object or person is said to be stable. When the line of gravity falls in the exterior of the "bos" ( buisness operating system) , the object or person is said to be unstable. ... A larger "bos" increases security (the line of gravity must move a greater distance to fall outside the "bos") Although the gravitational force the Earth exerts on the objects is diverged. Their masses are just as different, so the effect we watch (acceleration) is the same for each. The Earth's gravitational force accelerates objects when they fall. It always pulls, and the objects constantly speed up.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
