Thank god for physics[8D]
What is being said is momentum is what really determines penitration for an arrow, it is the resistance to change of velocy/direction (meaning what keeps the arrow moving through an animal).
Without getting technical, strait line momentum of an arrow is greater w/ high FOC. (Moments of Inertia anyone[&:]?) Therefore, high FOC is preferable. How great of a difference does FOC have? That is the question....
Kinetic Energy does not directly relate to penetrating ability for archery although it does have useful comparative properties.
Thank you JoeRe!
That is what I was trying to say but my brain and fingers aren't connecting today.[8D] Basically from what I understand Momentum is MUCH more important to good penetration than Kenetic Energy.
