Dumb Question/Momentum and Broadheads
 

I am just reading over on GMMAT's analytical thread[8D], and I have a couple questions.

1. Where does momentum effect the penetration of a razor sharp broadhead?

2. How does speed effect the penetration of a razor sharp broadhead?

I realize the weight of the broadhead is usually around say, 1/3 or less of the total arrow weight. So, if you shoot an arrow with a broadhead of say, closer to 1/2 the total arrow weight, would this in fact give better penetration? (with the same identical bow setup) Is it not going to give you slower speed getting downrange and therefore less penetration? Remember, we are talking razor sharp broadheads here. So if I shoot a a.)400 gr(total arrow weight) vs b.)600 gr(total arrow weight), same razor sharp broadhead at say, 30 yds, except one bow is shooting this arrow a. at 320fps and b. at 250 fps, which one has more penetration and why?

The faster one, its common scense... Think about this into ballistic gel so we get the same target every time.

The answer to 1 is on a heavy bone hit.

2 will be debated but the fact is friction decreases with speed but
resistance increases.;)

IMO,Heavy bone doesn't really care how sharp the head is.

RE: Dumb Question/Momentum and Broadheads
 

Momentum is a measure of penetration potential, so is KE.

RE: Dumb Question/Momentum and Broadheads
 

Definitely not true ..... the sharper the head, the more it will penetrate heavy bone .... think of an axe...

RE: Dumb Question/Momentum and Broadheads
 

Velocity squared X weight divided by 450395 will = kinetic energy.:eek:

That should add to the confusion.;)

Actually, that makes sense to me .... maybe cuz I have been teaching it for years..... let' go fishin Jimbo :D

Its raining here in North west PA's newest rain forest, the hell with deer season we're gonna be hunting monkeys and listening to parrets if it don't stop raining soon.[:-]
If it stops raining some time soon I might hit the lake at the end of the week, this low pressure front is killing us.

LOL! ..... it's been the same here ..... I feel like I'm in Florida ...torrential downpours .. thunder, lightning, and then .... sunshine .... then back to the rain ... it's nuts ...
