Barrel ? sounds and distants.

If TK told you, would you beleive it?

You're not the first kid who thinks the rules of physics are "different" just for paintballs.

If you want "The Truth", I recommend some reading in the archives. It's been discussed here, ad nauseaum...

no because the people that have showed me have played as long as tom has, have mroe science/math background than tom and one personaly knows tom but none of that matters.

if you want to start talking about the physics of paintballs, work out far a ball should travel with all the given factors, the balls dont fly how they should on paper.

i know you are sitting there thinking "kid you are an idiot" but frankly i know im right because i have seen it proven to me and been showed/told by multiple people who arent your average joes by any standards.

if they are both leaving the barrel at the same speed, what is making that ball go the extra feet?

[SR_matt]

it has to do with the way the force gets imparted to them (from the best of my understanding) with a low pressure gun the ball get brought up to speed over more time. best reaoning i have came to is that the hp gun the ball is starting to slow down becasue of drag in the barrel so the the drag leads the ball to keep slowing down slightly faster.

im not talking feet of differance but like stated before its gives enough to be able to get the long shot that normaly wouldnt break.

the main part of this is that way the force gets imparted, not much to do with the barrel length but more so relating to the pressures.

your reasoning is dizzying.

Matt, it's a state equation... All that matters once an object is put into projectile 3 dimensional rigid body motion is mass, velocity, and excess accelerations (wind drag, gravity, rotational effects, ... , bird poop).

Forces aren't inertial, nor is acceleration or jerk (acceleration of the acceleration). Once you stop applying a force or acceleration, it is gone and has zero effect afterwards. It's like a unit step function, if you've ever seen one - one second it's effects are there, the next they're not. Basically, the object accumulates a certain finite amount of energy which is independent of how it took the energy to be built up, namely it's kinetic energy --> KE = .5mV^2
Sadly, as you can see, there are no time dependent variables other than Velocity in that equation - and even the acceleration that imparts that velocity accounts for the length of acceleration in the F=ma derivations.

What I mean by that is if you slowly accelerate something to a velocity of say 200 mph, and you quickly accelerate something to the same speed - at the release both object have the same speed and direction ... therefore, it can be mathematically proven both will have the EXACT same flight path given similar drag forces.

And to say that something hits with more force to cause a break than something else traveling the same speed is ludacris... objects in flight have a finite energy KE = (1/2)mV^2. I'm sorry Matt, but I don't care if your friend you speak of is Socrates or even einsten... he is wrong. Your statements make Newton roll over in his MFing grave

Do you ever wish kinematics were manditory in school?...I do

Me too.

You SR Matt have been show to believe people with egos greater than their ability to reason. Pneumagger gave it to you straight it doesn't get much simpler than nothing is different once the balls leave the barrel. Same paint same speed same results. 12-14 is as good as it gets.

Personally I really like the porting on J&J barrels and find them to be pretty quiet.

[SR_matt]

most of the factors related a lot mroe the pressures than to barrel lengths. i know most of you will not even consiter what im saying becasue im younger and becasue "on paper it says..."

well i really havent got any were with this thread. one guy say one thing another somthing else. So any way.. maybe someone can answer this one correct. When measuring a barrel is it from the hole were that ball enters? So what barrles do everyone like and use. i dont want to have to by like 15 of them. rifeled any good...

I agree with Matt here guys. I hear the verdict is still out there on that "math" stuff.

It has NOTHING to do with your age, it has to with FACT!

Dude, the laws of physics are NON-NEGOTIABLE, regardless of what your so-called "experts" are telling you! Want to learn more? Take some time and search for the many posts that talk about barrel length & distance.

Welcome to the internet. When you ask a question, you have no idea whatsoever who is actually answering...could be a smart-assed 10 year old, or an engineer with 20+ years experience in all things paintball. You roll the dice, and take your chances!

Instead of looking for easy answers, reasd all you can. Have you read "Tom's tech tips" yet? Spent any time looking through the "Deep Blue" forum?

My barrel recommendation? Buy a Lapco Bigshot barrel. One of the best availble, at any price
