What is angular velocity equal to? It's a formula about time t
The angular velocity W is equal to the rotation angle D divided by the time t, that is, w = D / T
For uniform circular motion, if you rotate one circle, the rotation angle is 360 degrees, which is expressed as 2 π in radians,
If the period is t and the time taken is t, then w = 2 π / T

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?
