RE: KE vs. Momentum
Just read the thread you are refering to Curtis and it does not make sense to me. Sure arrow speed and arrow weight produce KE. DUH speedx speedx weight/blah,blah=KE. Speed and weight is KE.
Now his referance to momentum, he is implying that arrows of different speed and/or weight but equal KE arriving at the target will some how have a different value?????????? As he said there is no scientific evidence just his opinion. To me KE is the amount of punch at the target and if they're the same they're the same
