Is the angular velocity of uniform circular motion equal? Is the magnitude and direction equal?

For an undeformed object, the rotation angle of any point is the same, so the angular velocity is the same. The magnitude of angular velocity describes the speed of circular motion around the center of the circle

Then we have v = w * r In this section of theory, why do both of them represent radian rad? Is it because V / r = w in V / r = 2? But this conclusion has not been deduced yet```
7. Relationship between angular velocity and linear velocity The linear velocity is equal to the angular velocity times the radius according to the formula Angular velocity is 2 pies divided by period, linear velocity is 2 pies multiplied by radius divided by period The angular velocity is 360 degrees divided by the period, so the linear velocity is not the angular velocity times the radius For example, when the earth revolves around the sun, the angular velocity is about 1 degree per hour, and the linear velocity is not equal to the angular velocity times the radius. Why?

13. The formula of angular velocity cannot be fully understood! In the formula of angular velocity (i.e. w = 2P / T), isn't 2p a fixed value (i.e. 360 °)? Why can it be calculated by the angle equal to the actual rotation angle (e.g. 90 °)? If it is known that the angular velocity of a circular motion of an object is 50m / s, it only rotates 90 °, can it be directly removed by 2p, and the actual rotation time t (T) can be obtained by the angular velocity of 50M / S?
