How about this.
Hitter #1 has 60 mph bat speed at contact, but uses all arms.
Hitter #2 has 60 mph bat speed at contact, but uses all the muscles of the body.
Which ball goes further?
they go exactly the same distance
Just the bats mass and velocity....if you read this godforsaken thread you will see links to several studies showing that due to the way the energy wave travels in a bat that what is happening at the handle has absolutely no effect on the bat ball collision. The collision is so fast that energy cannot travel fro the handle to the sweet spot in time.
So several independent physicists on at least two different continents run tests, gather data and match it up against theoretical results, the findings show that during the bat ball collision that how the bat handle is clamped cannot possibly have an effect on the ball exit speed. The experiment and the theory match, other sports science labs confirm the results, ESPN sports science confirms the results, but we have two guys throwing balls at bats in the backyard and refuting it.
Sounds a lot like the global warming debate to me. Science up the wazoo proving it is happening and yahoos going in the backyard and saying "feels cold, this global warming stuff is a bunch of hooey"
JJ read what I wrote again. I agree with the scientists. The wake forest (?) test with the bat on a string and the clamped bat showed what everyone suspected, the bat on a string goes flying and the clamped bat doesnt. (Read this) things change when the bat is put in motion.
And yes I believe in global warming, cooling and changing climate. What does the data show 3/10 of 1 degree change in the last 100 years or so?
