How to understand the direction of angular velocity of an object in uniform circular motion? Angular velocity is a vector, it has size and direction. Size is calculated by formula, but how to understand direction? The textbook says: the angular velocity of an object in uniform circular motion is constant
Angular velocity is a vector, not required in high school
The angular velocity is constant in uniform circular motion
The direction is judged by the right-hand spiral rule, that is, the direction of the four fingers is the direction of the linear velocity, and the direction of the thumb is the direction of the angular velocity (along the axis of rotation)

We can get V / r = 2 π / T, and w = 2 π / T, then both of them represent radian rad, and they can be reduced. 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```
- 9. 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?

- 11. 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?
