Re: Re: Bat speed vs mass

> > Great Post and answers...just found this site and it is very
intriguing......but in regards to the information in regards to bat
mass vs speed......am i correct in saying that a 30 oz bat swung at 68
mph will cause the ball to travel further than a 28oz bat swung at 68
mph? Of course all other things being equal?

68 mph, which would be the more desirable option....all else being

is to get bat mass. A ball will travel farther when a heavier bat is
used if a hitter was able to use a heavy bat plus swing with the same
velocity of a light bat while hitting in the center of percussion.
The problem for most mortals is that they cannot swing a heavier bat
as fast. I don't know anyone that can swing a 42 ounce bat as fast
as a 33 ounce bat, including Barry Bonds.

I'm guessing that, in general, the bat you are most comfortable with
will be the one to best suit you. It's one of the oldest equations in
physics: Force = Mass * Acceleration. In other words, the greater the
mass of the bat, the more force it can impart to the ball. But at the
same time, a hitter cannot give a heavier bat the same amount of
acceleration as he can a lighter bat. Certainly, this doesn't happen
in a vacuum and other factors apply, such as the distribution of
weight of the bat itself, amount of spin imparted to the ball
(lessening the overall linear force imparted to it), etc. There
probably IS a minor advantage one way or the other, but I'd advise the
hitter to find the bat that he can swing WELL and consistently contact
the ball at the sweet spot with. Work on the mechanics with THAT bat,
because if you try and tweak every little thing, every time, it will
be harder to develop the consistency.
