You say $\omega$ has "a direction perpendicular to the plane of rotation" and yet is not along the axis of rotation. I would think these are the same directions. And you're saying that the angular velocity vector does not lie along the axis of rotation, and yet we say it does? | |

But to avoid any confusion( as mentioned in answer), we chose $\omega$ to have a direction perpendicular to the plane of rotation or into the plane of rotation. Does angular velocity actually lie along the axis of rotation ( parallel to it) , no, but we claim so only to eliminate any possible physical conflict in solutions to problems. It's like a convention of sorts. As you can see in the formula you mentioned above, we basically use the screw rule to figure out the direction of angular velocity. | |
