Rotation vs Vorticity - What's the difference?

rotation | vorticity |

As nouns the difference between rotation and vorticity

is that rotation is rotation while vorticity is (mathematics|fluid dynamics) a property of a fluid flow related to local angular rotation; defined as the curl of the flow's velocity field.
