Centrifugal acceleration (source code)

= Centrifugal acceleration
{title2=$-\boldsymbol\Omega\times(\boldsymbol\Omega\times\mathbf r)$}

In a uniformly rotating frame, centrifugal acceleration points away from the rotation axis and equals $-\boldsymbol\Omega\times(\boldsymbol\Omega\times\mathbf r)$.
