Best way to nudge a ship

[icedown]

What is the best way to give a whole ship a little nudge, similar to a decoupler?  I want to use a little "magic" to give the vessel a nudge and not start it flipping. I've found RigidBody.AddForce and Vessel.ChangeWorldVelocity but I'm not sure which one I should use or if there is a better way.

Decouplers use addForce

Change world velocity for me has caused problems (producing a far larger force than required), so I would recommend RigidBody.AddForce ; although I have not yet used this personally.

Edit:

This post here shows some good information on how to add a force and adjust things, hope its useful!
