>>> Constant velocity does not make sense to me. Acceleration is the change of velocity over time. If it's constant then acceleration is zero. You need to find a bat that allows you a faster increase in velocity through the hitting zone. <<<

Hi Mike

I would guess you are referring to my following paragraph. “ The basic formula for the amount of energy impacted to the baseball at contact is f=ma or f=mvv. This means that for a constant bat velocity, doubling the mass of the bat will double the impact force. However, doubling the velocity will cause the impact force to be four times greater. Therefore it appears that increasing bat velocity is more important than increasing bat weight.”

By “constant bat velocity,” I am saying that for a “given” contact velocity, doubling the mass of the bat will double the impact force. I did not mean to imply a batter should strive to maintain a “constant bat velocity.”
