Coriolis Force, Motion of projectile

[jiho.j]

I've been wonder something about coriolis force.

Well... when we consider motion of projectile on earth, we have to consider coriolis force due to Earth's rotation and we know that coriolis force varies with latitude.

In the book (fowles's) they set differential equation and just integrate them without considering latitude change. well... I mean I think latitude varies when particle is moving. But why they are not consider it? can we just ignore it? or is it my misconception?

sorry for my english. English is not my mother tounge

 

[A.T.]

we know that coriolis force varies with latitude.

The component parallel to the surface, related to movement parallel to the surface varies with latitude.

The total coriolis force related to the total movement doesn't depend on the latitude.

An interesting article for those interested in the history of the Coriolis phenomenon:
