Ohh I see. So it's like the moon where the moon just needed to be set with a velocity around the Earth at some point long long ago and now it's just technically falling towards Earth?

Does it get there because..
first the rope is pulled up
the ball gets pulled in the same direction as the rope
then the rope is pulled perpendicular to the ball's motion
then the ball starts going in a circle pattern because of the ball's inertia?
And the direction of velocity of the ball keeps getting changed which is why it can't just get pulled into the center of the circle it's making?

I've not learned notating polar coordinates those ways :o
