in the vector form ,


   v = w x r


if the body does  planar circulatory motion about an axis , then its w willbe


  w = v/r   , if the rotation is anti clockwise then w vector will be up the plane , otherwise  below the plane


if the situation is diff. & velocity vector is not perpendicular to the position vector , then w will be defined with the help of component of velocity perpendicular to the r


w = v cosx /r


& if the sense of rotation is anti clockwise then w vector will be up the plane , otherwise  below the plane
