RE: Speed vs Energy?
A certain bow makes " X" amount of energy period. Going from a finely tuned arrow at 10 grains per # to a finely tuned arrow at 5 grains per pound from the same bow, at the same draw weight and length you will usually see the heavier arrow sport 1-3 foot pounds more of KE. |

My setup is 72lbs heavey arrows 7595xts gets 288 fps.my bow is quiet but under 35yrds it does not matter at that speed. Whether I shoot muzzys or rockets I get pass troughs that what I try to acheive, it leaves 2 blood trailing holes if they go any where at all.

450240 or 450800? It depends on whether you use 32.16 fps^2 or round it off to 32.2 fps^2 as the gravitational constant in the calculation. Doesn' t amount to any major difference to the end result in the KE formula, at least for our purposes.

RE: Speed vs Energy?
I just came up with a calculation for momentum on another forum & it' s kinda interesting. Arrow weight in grainsXfeet per second divided by 7000. Yields momentum supposedly. I don' t know if this is an official deal or BS, but it is interesting.

There are 7000 grains in 1 pound.
