RE: What is the best way to get kinetic energy II
 

That thread is really screwed up. I suggest for those of us who want to continue that we do it here...

RE: What is the best way to get kinetic energy II
 

The quickest way to get KE is to increase your speed. The quickest way to increase your speed is to make your draw length longer. If the draw length is too long you won't shoot accurately.

RE: What is the best way to get kinetic energy II
 

How do you increase your draw length?

[There now things are working!]

RE: What is the best way to get kinetic energy II
 

If you shoot a loop take it off. That will gain you a quarter inch...

RE: What is the best way to get kinetic energy II
 

With a 30" draw 7" brace and 60 pounds initially shooting a 350 grain arrow 265 ft/sec a 1/4" increase in draw buys me only 0.6 ft/lbs KE and 0.002 slug ft/sec momentum.

RE: What is the best way to get kinetic energy II
 

My point exactly, increasing your draw length is usually not an option. Like was stated in the previous thread, it's obvious that a heavier arrow will increase down range KE and momentum.

I just try to find a happy medium of trajectory, arrow weight and KE/momentum and put it in the boiler room

RE: What is the best way to get kinetic energy II
 

I agree completely. The discussion about KE and momentum is interesting and I enjoy talking about it but most of us are delivering plenty of energy/momentum and having more of it won't make up for poor shot placement.

Sylvan, on the other thread you asked why I use pound-seconds instead of slug ft/secs. I use pound-seconds because that is the way the ballistics program I use lists it. If you want to convert my figures to slugs, be my guest. They are the same values, just a different (maybe old fashioned?) way of listing momentum values.

For those of you who don't have a clue what we're talking about: Slug - The unit of mass that is accelerated at the rate of one foot per second per second when acted on by a force of one pound weight.

RE: What is the best way to get kinetic energy II
 

Interesting, I've never seen momentum referred to in pound/seconds. I wonder why they do that seeing that momentum = mass x velocity and the pound isn't a unit of mass and seconds aren't units of velocity. Slug ft/sec or kilogram meters/sec if you like the metric system are typically what you see in physics/mechanics. Technically what they use is incorrect. I didn't check your values but they appeared to be values that made sense as slug ft/sec. Anyway it isn't a big deal I just have never seen it.

Yeah, eventually somebody's gonna come along and list things in Newtons and really screw us all up. [8D]
