Wow, we're on this subject again. Must be the off season[&:]. I really don't understand how anyone can say that heavier arrows will always increase momentum and KE. When one keeps increasing the arrow weight, the closer that velocity approaches 0. There has to be a breaking point to where arrow weight will start to harm penetration. Momentum and KE just can't increase into infinity.
I think that they can. In fact, I am sure of it. But, you make an excellent point about penetration, so I have slightly changed the question.
WHAT IS THE MOST EFFICIENT ARROW WEIGHT FOR MY SET UP?
How can momentum increase infinitely? Momentum simply means "mass in motion". If the velocity is 0, the object's not moving-that object has 0 momentum. Your revised question, however, is a great one.
