Think of billiards. With some force, a ball can roll on a flat surface. When I had asked a question about calculating rotation for a rolling ball, someone wrote an answer that I should use Rigid Body. But the Rigid Body introduction video was using a slope. I want to roll a ball on a flat surface.
So, if I have an active Rigid-Body ball and a passive Rigid-Body plane, can I push the ball slightly so that it could roll a little bit and stop (like billiards)? Or must I use a slope?
