Im working on a project whereby an object can emit thrust from various points on its surface but can also be pushed by general forces such as wind etc.

Any ideas where i can start with the maths. I am aware of adding forces etc. but all the examples i've ever done/seen all have the forces all coming from the centre of the object.

Im guessing the best example would be a lunar lander type craft with RCS thruster on it.
