After that the elasticity of the ball and bat, and the angle of the impact come into play. Maybe the spring rate of the bat as it bends and springs back on impact -Maybe. I'm not sure the spring back is fast enough to give any energy back to the ball.

And no, I don't recall the formulas for most of that. I haven't used them in around 25 years. (There's also some very complex stuff involving the ball passing through the air that I've never really gotten the math for. I understand the concepts, but not the calculus)

Basically, yes, faster bat=more distance than heavier bat.
Unless you have slow hands like me, then the heavier bat is better.
