CBSE Class 11-science Answered
Is it necessary that the direction of the angular velocity and the angular momentum are the same? If not, Why?

Expert Answer
No, it's not necessary.
Angular momentum: L = r x p = r x (mv) = m (r x v)
(r: position with respect tot origin, p: linear momentum, m: mass, x: cross product)
Also, linear velocity v = w x r
(w: angular velocity)
Therefore, L = m [r x( w x r )].............. a vector triple product.
(solve using your knowledge of vector triple product and find the direction of the resultant L)
Hence, direction of L is different from that of w, in general.
