For ten points, name this force which is responsible for the rotation of hurricanes and the deflection of artillery shells.
In electrodynamics, its analog is the Christoffel voltage.  In the Navier-Stokes equations, it is propotional to omega cross v where v is the velocity and omega is the rotation.  It arises using Newton's laws in a rotating reference frame.  For ten points, name this force which is responsible for the rotation of hurricanes and the deflection of artillery shells.
