When I was a kid, I remember my physics teacher telling my class that if somehow you could throw a curveball in space, it would go in a full circle back to you, basically hitting you in the back. Now, this seems like pure bunk to me in hindsight, but I got curious about the mechanics of a curveball. I was less curious as to how to throw one and more curious as to why a ball curves. There is a ton of information out there, but I settled on the link for Day 12 because it had some nice graphics to show what is happening with the ball.
(BTW, it looks like my teacher was wrong…If the ball requires air resistance to curve, that isn’t happening in the vacuum of space…but I did nearly fail physics that year.)
