The family physician often provides the first and only medical intervention for fingertip injuries. Proper diagnosis and management of fingertip injuries are vital to maintaining proper function of the hand and preventing permanent disability. A subungual hematoma is a painful condition that involves bleeding beneath the nail, usually after trauma.
I think it's probably easier to flip the question, and find why angular velocity is equal to the linear velocity divided by the radius: [math]\omega = \frac{v}{r}[/math] From there, it's a simple algebraic manipulation.
The magnitude, or length, of the angular velocity vector is directly proportional to the angular speed, and is measured in the same units as angular speed (radians per second, degrees per second, revolutions per second, or revolutions per minute).ngular velocity, also called rotational velocity, is a quantitative expression of the amount of rotation that a spinning object undergoes per unit time.
