We tried a little experiment today. We shot 3 arrows with different weights, same bow same draw weight and DL. As for the results, thegrains/velocity were 358/256, 500/221, and 1242/144. The KEs were approximately 52.11, 54.24, 57.20 respectfully. Although the PE "for the bow" should be considered as constant, "my bow" appears to be moreefficient intransfering itsPE to heavier arrows. This also indicates that there may be significient losses in the transfer from thePE to KE process dependent on the arrow weight. (neglecting any effects do to the spine for now).
Could have fooled me.
Heavy arrows absorb more of the bows pe than does a light arrow.The energy gets waisted,in lamens terms, when using light arrows.
We were talking about power stroke as being the distance the string travels and that gets translated as time on the string,kinda like when ke gets referred to as potential penetration.
