Coriolis Force – Conservation of Angular Momentum
UA
UB
Absolute angular momentum at A = Absolute angular momentum at B
UA * (radius at A) = UB * (radius at B)
UA * (Earth’s Radius * Cos(latitude at A) = UB * (Earth’s Radius * Cos(latitude at B)
UA = UB * [ cos(latitude at B) / cos(latitude at A) ]
UA > UB
č A northward motion starting at A will arrive to the east of B due to the
     conservation of angular momentum
čAn apparent force (Coriolis Force) = f V,  where f = 2*W*Sin(lat) 
                                                                   where W=7.292x10-5 rad s-1
