Relative force

Hello? Is here a way to get relative force?
I need it because I add for to my space ship for moving and I like to stop it.

Try and take a look at Unity’s documentation before posting questions. It is really is quite extensive and very easy to find what your looking for…

You can use AddRelativeForce to move your spaceship. If your going for a more “Newtonian Physics” kind of realistic control you can use get velocity and get angular velocity to calculate counteracting forces.
