Baseball's Black Hole - Terminal Velocity

[SAump]

Consider the terminal velocity of a baseball. It has been mathematically proven to occur at 73.8mph. A knuckleball or curve ball released at 80mph may decelerate to 73.8mph over the plate. Are these "strange" effects sharply noticed at any other velocity?

Wind tunnel lab experiments confirm similar baseball terminal velocities between 92 and 94mph. A 4-seam, slider, cut or sinking fastball is released at 100mph and decelerates to 92 mph at the plate. A faster spinning 2-seam fastball doesn't decelerate or move as much. Are any of these "strange" effects comparable at other velocities?

The ball physically "hops" twice, at 73.8mph and 92-94mph in the air we breath. There is direct evidence from wind tunnel experiments available. There is indirect evidence available from MLB hitters and umpires. Consider it a decoupling in the air waves, similar to a sound barrier, around the baseball while passing through its terminal velocity.

It makes me want to sit back and take a breathe.

Too much physics for a Monday morning. The article you posted has no flow, it doesn't explain concepts, and it is just incomprehensible. Why can scientists not write anything in english?

Anyone who doesn't think a fastball can rise hasn't been calling a high enough caliber of baseball. The reasoning that because gravity pulls something towards the ground, therefore a fastball cannot rise, leaves out too many important facts.

Oh cripes, now SA has another uniformed follower.

Mate, over the last 10 years this site (and others) have proven time-and-time-again that a baseball thrown overhand CANNOT rise.

And trust me (unless your an ex-major leage umpire that worked in season games) I have called a higher caliber of baseball than you my friend.

I hope no one else wastes their time answering yet somone who lives in the "mythical land" of the rising fastball.

~Sigh~

Would someone, please, PLEASE, lock this thread.

[Emperor Ump]

Mythbusters busted the "rising baseball" myth in their baseball special a while back.

[Tim C]

I saw the Myth Busters piece. I also read and watched at least 10 other definitive studies that show gravity does work.

I guess we'll always have people that choose to live in "Myth World"!

I especially like those that try to shout us down by saying we don't work "high enough quality" of baseball to have seen this.

Sad, just sad in a way.

I was strictly talking terminal velocity. The baseball does "silly things" at or near terminal velocity.

Pretty good "science-fiction" analogy posted by member tornado, both classy and intellectual.

Key words in comment include turbulent flow, vortex channel, vorticity, etc.

Do you have any idea what "terminal velocity" means?

Please stop posting this crap.

Judging from his post, no, he does not.

ter·mi·nal ve·loc·i·ty
• n. Physics the constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration.

[Kevin Finnerty]

Terminal velocity is the speed that a train is traveling when it goes right through a train terminal without stopping.

I can't believe more people don't know that.

There's a simple explanation for this part. As for myself, I will trust Tim (and gravity).

On the other hand, he linked a Wikipedia article, so he must be right...

Once again who gives a rats anus-- and who gives a flying fornication. Next time we all need to band together and make sure there are no responses to a post like this, matter of fact, nothing personal (as this is directed at the post and not the person posting this), but I will not even open it to read. Let's follow Tim_C's lead. This type post is counterproductive on this site. It belongs on a physics post with Earl Weaver who I'm sure would be interested and love to hear all about it before he comes out of retirement or passes on to managerial heaven.

I can seem to find the link to add someone to my ignore list. Has that feature been removed?
