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.
Angular momentum [edit]. Angular momentum of an object revolving around an external axis O is equal to the cross-product of the position vector with respect to O and its linear momentum. Angular momentum of a rotating object is equal to the moment of inertia times angular velocity.Torque is equal to moment of inertia times angular acceleration, which is also equal to the change in angular momentum divided by time taken.Rotational Kinetic Energy is equal to one-half of the product of moment of inertia and the angular velocity squared.IT IS USEFUL TO NOTE THAT.ngular momentum [edit]. Angular momentum of an object revolving around an external axis O is equal to the cross-product of the position vector with respect to O and its linear momentum. Angular momentum of a rotating object is equal to the moment of inertia times angular velocity.
