I don't understand what are the causes of the Coriolis effect for objects moving with respect to Earth. For istance consider an object free falling on the earth from an height [itex]h[/itex]. Its tangential velocity its greater than the velocity of an object on the surface of Earth, hence it moves eastward (in the direction of rotation) while falling. But does it end up here? Is a kinematic consideration sufficient to explain completely the Coriolis effect in this case? Or there is something else, like conservation of angular momentum? If so how it is influent in this case?
