First off I didn't make up any laws of physics.It is a law of friction(therefore a law of physics) and was found in my machinist handbook with the explanation I gave.It is a law of mechanics and that is why it is found in my machinist handbook.Look it up in your handbook Arthur,if you still have one laying around.I even pointed out it is a law of dry friction and this may or may not apply.


Like I said,for arguments sake and it doesn't take much to get Arthur going.


These little ,for the sake of argument tidbits are the way people get informed and learn.Chances are if you are reading this thread and tring to weed through the bs,you are already way ahead of the game when it comes time to take an animal with your bow.


Funny thing is I just built my turkey arrows and weighted them down and will get way less penetration because of it.Before you stroke Arthur,I added weight to the back of my arrows to help overcome the 150 grain 3 1/2" cut expandables[] I put on them.So I am shooting way heavier and will get way less penetration.These are the type of info we should be concerning ourselves with instead of just heavy verses light.
