Main Question or Discussion Point
What effect does rotation have on a sphere moving through a fluid (liguid or gas) when travelling along the axis of rotation? The simplest being an up or down motion.
I don't know, but I would guess that it would not unless the spinning somehow caused there to be less friction on the object.Yes, exactly. Like rifling for a bullet or a stabilizing spin for a football. However, I'm wondering more about whether it would affect velocity or general momentum.
That's just it! Does the spinning cause the fluid to move in a way that DOES decrease the friction? Or does the object somehow acquire more energy from...somewhere?I don't know, but I would guess that it would not unless the spinning somehow caused there to be less friction on the object.
