Im just wondering how does your arrow effect your ke shouldn't it be the same with every arrow out of the samebow unless there is something slowing it like when its unknocking cause ke trasfored from the bows potential energy so i don't know how the differnt arrows would effect that a lighter arrow has more speed and a heaver arrow travels slower but there ke should be the same if im not mistaken
Not true at all. The heavier the arrow, the more efficient the bow is at transferring energyto the arrow. A lighter arrow will cause your bow to be louder and have more vibration. This noise and vibration is lost energy. A heavier arrow, although slower, will absorb more of the bows energy. That's why a heavier, slower arrow will usually pack more KE than a lighter faster arrow. And a heavy arrow will always have more momentum than a light arrow. That's why the traditional guys can shoot heavy wooden arrows at 150 fps and kill big game.
