I’m not sure if what I’m looking to do is possible.

I would like to have two planes. I want Plane B to be attached to Plane A on a pivot, so that it’ll swing from side to side, but that’s it. If Plane A movies, Plane B should move with it. Then I want to apply physics to Plane B so that if Plane A moves, Plane B will flop around and spin around the pivot point from the force of the inertia.

Is this possible? Thank you.
