Baseball physics question

  1. Dec 20, 2014 #1
    Okay so I'm not sure if this post should go here but I would like some help figuring out a baseball related question. I have a 33" bat that is 30oz that I average 84mph swing speed at contact with the baseball. I tried swinging a 34" bat that is 31oz that I average 81mph swing speed at contact. Is there any way to determine which bat I should use to maximize ball exit speed off the bat?

    Is the 1oz bat difference make up for the loss of 3mph swing speed at contact?

    You can look at which bat gives you more momentum to transfer to the ball.

    I've read that moment of inertia is an important factor in the swing speed I'm able to generate with a certain bat. Easton even has an MOI rating for their new line of bats. How would I figure out what gives me more momentum?

    This may not be a question, so I'll comment: you do see which of the two bats is which, and which you're swinging faster?

    Not sure I understand your question. I took 100 swings with each with a sensor attached to the bottom of the bats and got an average swing speed for both bats, if that's what you are asking.
