Give the expression for the angular velocity of a body in terms of radius and velocity vectors. Represent the direction of angular velocity with the help of a neat labelled diagram.

Text Solution

Verified by Experts


Form the figure,
`vecomega=vecrxxvecv` and `vecL=Ivecomega`
Direction of `vecomega` and `vecL` is perpendicular to the plane of `vecr` and `vecv`. The angular velocity vector lies along the axis of rotation.
