Cool just say that from now on as to not disrupt my professor spidey sense since I know that
is of the upmost importance to you...
Grrrr..come on @Work=wins do you really not get the idea that ALL SWINGS CONSERVE ENERGY.
I get it. But when delivering the ‘conserved energy’ into the ball, all swings do not conserve energy the same. That’s been the point the whole time. You are so busy worried about definitions that you are missing the point.
It would probably best suit you to look at the swing through this lens since you understand ‘physics’ so well. Stop looking at it from a speed aspect and look at it as conserving energy and delivering it to the ball the most efficient way. ?
