I'd go with vector calculus to approach this kind of problems.

A module would need to be able to define vectors as objects and overload operators for addition, subtraction, scalar product and vector product.

There are plenty of modules in the geometry / algebra / math / pdl namespace, not sure which to recommend, personally I might start with my own toy project to play around with overloading.

update

Salva's module looks pretty much how I'd envision it. :)

(though I might ponder about allowing 2d cross products by adding a third 0 component)
