This question already has an answer here:
I was going to ask something very similar to this question (which hasn't been answered). Basically a camera fell from an airplane and it began to rotate (maybe because initially it was put in rotation by the hand from which it fell) but then it stabilized! I saw the same phenomena with Felix (the guy from red bull Stratos), though I think the stabilization occurred because of the little-mini-parachute that skydivers use to stabilize their descent.
My question is, does terminal velocity have something to do with this stabilization? GoPro cameras are like a cube, so intuitively, when the cube reaches terminal velocity it will receive the same force throughout the surface that points downwards, if it's not rotating, it will remain stable, if it is rotating how does this "uniform" force over the rigid body stabilize it?
I appreciate your thoughts on the problem.
