Velocity and angular acceleration

[Zeno's Paradox]

Is this true?

$$\vec \omega \times r = \vec v$$

 

[neutrino]

That's actually meaningless.

This is true:$$\vec {\omega} \times \vec{r} = \vec {v}$$

(with respect to fixed origin)


Assuming omega is the angular velocity, r position vector, and v, the tangential velocity.
