ship physic
Author
I making a game about ships in the 17th century.So I wonder what kind of physic do I need to calculate wind and drag in the water and stuff like that.

I don''t have an answer for you, but I do know that the book ''Physics for Game Developers'' (I think that''s what it''s called - the one with the cat and mouse on the front) has a section on ship physics.
Most things like drag usually just have a coefficient tied along with with. For wind drag I''m pretty sure it''s something like this:
Fdrag = CdragV2 where V is the velocity and Cdrag is the drag coefficient. I''d imagine it would be the same for water drag.
Fdrag = CdragV2 where V is the velocity and Cdrag is the drag coefficient. I''d imagine it would be the same for water drag.

You're forgetting the density (rho) of the medium being moved through:
Drag = 0.5 * Cd * Rho * V^2

Hi,
You will need to take the shallow water effects into account as well as sail aerodynamics ( not as straightforward as it seems but lots of emprical info is available ).
