{{page>wiki:headers:hheader}} Navigate [[..:..:..:activities:link|back to the activity]]. This activity makes a good kinesthetic activity. For the Coriolis acceleration, designate an origin, then ask students to hold their arm out in the direction of $\rr$, then to determine the direction of $\Omega\times\rr$, and finally to determine the direction of $-\Omega\times(\Omega\times\rr)$. For the Coriolis accelerations, ask students to stand up and face in any direction they choose --- their velocity $\vv_R$ --- then have them work out the direction of $-\Omega\times\vv_R$.
