Proof that an autococker shoots further?

[strongboy2005]

see the way this relates is that a chrono is just a snapshot, it doesn't measure how fast the ball will be traveling 10 feet later.

What's with this pluralized usage of "you?"

I have to agree with Army. This thread is getting absolutely rediculous. The only force that matters on a ball after it leaves the barrel is air resisitance, which is going to be the same on every ball from every gun.

Have any of you acutally taken college level physics (those of you that think one gun can shoot further)?

Ok, well, it seems that strongboy is the only one that thinks the gun makes a difference, so i guess im talking to him

But we *know* it cannot be traveling faster, as there is no force present that can account for that, so what does it matter?

For the record, there was an implied smiley there. :)

Stongboy, are you serious, or are you just yanking our chains by acting so dumb?

Don't worry, I figured

i just think it's a good explanation for why cockers shoot furthur than mags. again, it's just a theory, and I'm just trying to have a friendly discussion of facts and some inferrences (when I test this I will bring this thread back to life and post my results, and conclusions that can be drawn from it) Of course the first thing i'll do is see if a cocker truly shoots further than a mag, and i'll get some pics of the test. screw it if they shoot the same distance, i will admit defeat. but if the cocker truly does shoot furthur then I want to know why, by experiments and hypothesis the whole works.

Stronboy...lol...What do you do for a living? I'm guessing it doesn't involve alot of thinking...

PLEASE PLEASE PLEASE tell me what force is acting on the balls after they leave the barrel that would cause them to accelerate...

Or....tell me why this is wrong

F=M*a or a=F/M

Deceleration forces are EQUAL. You can't put two different barrels into the equation if you are doing a comparison.

OK kids, last time, listen up: Both guns have 12" barrels. Both guns have perfect paint to barrel match. Both guns are running Flatlines at 850psi input (shameless corporate spam). Both tank are full. Both guns have been chrono'ed at 300fps, 4' from the muzzle (standard for radar bench type chronographs). There is NOTHING the gun can influence at this point. There is NOTHING the gas can influence at this point. NO FRICTION in the barrels will effect the balls once they are out of the barrels and have been chrono'ed. There is NOTHING the magic elves can influence at this point. Deceleration is EQUAL on both balls. Atmospheric pressure is EQUAL on both balls. Atmospheric resistence is EQUAL on both balls. The ONLY THING that can influence forward speed is atmospheric resistence, and this is immediately after the firing pressure can no longer accelerate the ball after 10" of barrel, and is constant inside the barrel and out. Gravity is a constant and will drag the balls to Earth at the exact same time and speed.

Whatever you have read or heard otherwise is WRONG and/or a lie. Let this ignorance end now:)

Read this one more time, it is true. Tests will only confirm it, if they don't, then the person conducting the test did something wrong. The same arguements in physics that are being used here are based on the same things that put people on the moon. If they are wrong, then Neil Armstrong missed the moon and is floating off in space somewhere.

hehe. well i'm a bionuclear aerodynamics engineer for NASA. (not really... LOL). but... I think the acceleration force is just going to be the lack of resistance and the left over air that is still being fired.

I'm curious as to why you would think that the cocker might shoot farther than a mag, particularly in light of tonight's discussion so far.

This, again, has shades of affirming the consequent. Why are you seeking an explanation to results that you have not observed?

Hehehe, thats pretty good.

if Gun A is accelerating and Gun B is decellerating then after the choron there will be a variation. If gun A shoots the ball from 0 to 500 to 300 (when the chrono takes the snapshot) then the ball will continue on decellerating to 175 then 120 and so on (again measurements are just for a mental image). gun B shoots it from 0 to 200 to 300 then the ball will probably hit 315 and then drop to 275 then 250 then 200 and so on, and as you can see they both chronoed the same, yet gun B decellerated at a slower pace, allowing the ball to travel at a furthur distance.

actually i did this so i'd know how to test it. if i could see flaws in the argument then I could formulate ways to test your concerns (and everyone elses) in experiments, which could either prove me wrong or right.
