Jack,

Re: http://www.batspeed.com/messageboard/output/19166.html

You need to read to understand the "linear momentum" term?...........

Positive effect would be, of course, staying inside the ball and prevent casting and staying rotational while performing this element to get your bat into position. WOW!!! I thought it was obvious, sorry!

I was wanting to know what YOU TERM THIS?????????...........
See the referenced link:

I appreciate your open forum,

Let people buy your DVD/Videos, lol. Your website is loaded!

I know you like to "guide" the discussion monthly with topics but I already am at a certain level in which you understand now, see the E-mail that I sent you.

Thanking You,
WT
:)

PS - Looking for what this is termed in the RE: link? It seems different terms(symantics) impeed progress on some of this discussions, trying to narrow that down or out with this question.

Hi WT

First of all, just because in frame #4 the knob is pointed at the pitcher when that frame was shot does not mean the bat has linear rather than rotational velocity. If you were swinging a ball around on a string and we took a picture that looked straight down the string, you would not say the string had linear rather than rotational velocity or momentum.

I think one of the hardest things for batting coaches to understand is that the linear velocity or momentum of a bat is not converted into angular momentum as the hands slow to a stop. That is why I made the video ( http://webpages.charter.net/nickkio/HandPath/ ) showing what happens when a bat is accelerated linearly (no torque applied to bring the bat-head around). That is why I asked you to “explained how "Linear Momentum" has a positive effect on the swing”.

WT, take a look at the clips and we can continue our discussion.
