RE: Does Kinetic Energy = Penetration?
<BLOCKQUOTE id=quote<font size=1 face='Verdana, Arial, Helvetica' id=quote>quote:<hr height=1 noshade id=quote>
Archery Program, I have a scenerio, Lets say that two different bows are used, with the exact same arrow. Both bows put out exactly 60 pounds of KE at the peak draw cycle. Now will the the KE energy of both arrows shot be the same at 40 yards out. Or, could there be a difference? Why?

First of all a bow doesnt put out KE, I will assume you are talking about stored energy for the sake of this question.
If both bows had identical draw length, brace height and draw force curves, and effeciency....the answer is yes. If any of these variables are different then the answer is no.
The reason for the above answer is simple. It's called string time for the draw length and brace height, and it's called force for the draw cycle curve and efficiency. An example would be two identical bows except for the draw length. Both bows set at the same poundage will store the same amount of energy, however the bow with the longer draw length will deliver a faster arrow and therefore more KE.
If you changed the question to read "If the arrows left the bow with the same KE" then the answer is invariably yes! We already know they are the same arrow so the only way they could have the same KE when leaving the bow is if they are also traveling at the exact same velocity.
Did this help?
