I will place below the address of a study that comes to the same conclusion as the bat company tests. Read it, especially the “Conclusion” at the end, and see if it changes your mind also.

Hi Jack

Very interesting read and being a biomechanical person I read and then reread very carefully and then analyze. I am concered that in the final experiment that the players hit off a tee. Since the ball is not moving it has no energy and thus is not a true test of two objects colliding and the resultant forces measured.

On the surface it looks like an example of how grips affect ball speed but if you dig a little deeper I believe that there maybe some faults within the study itself. Just like the presenter mentioned about previous experiments that were not true tests of the hypothisis this test though more convincing is also lacking in absolute conclusions.

I believe that the law of motion that states that an object in motion will remain in motion unless acted upon by another force and its resulting formulas would need to be explored more closely in order to find the final answer to this question.
