@JucoDad posted:My son throws what the old-timers call a heavy ball. There’s an optical illusion where the ball accelerates half way through its travel. It can’t really happen, but I think it’s how our mind does the physics - the ball should be there, oh shoot it’s actually much closer. The combination of ball appearing to speed up, and movement catching me in the lower palm ended our having a catch senior HS year (worried I’d catch one off the grill).
This is interesting and something similar may have been throwing off what I was thinking I was seeing that particular day. It probably was more in the mechanics that several mentioned. This was mostly incoming 9th and 10th graders, so mechanics were probably all over the place. I was just looking at it from a spectators point of view because I know nothing about mechanics. Thanks for the conversation!
