The Truth................

[Fooey]

my understanding

Ok, it's been while since i did physics but it's my understanding that if you measure an objects velocity at the beggining of it's journey, the only thing that will affect the overall distance travelled by that object is the objects weight.
As gravity affects a falling object at 9.8 meters a second per second, a heavier object would travel less distance but at a certain point this becomes constant and is then known as Terminal Velocity.

Therefore, if you crono'd two markers at 290fps using the same paint, sat them next to each other and fired the same paint through them, the only thing that would affect the distance travelled by the paint would be any differences in weight of each individual ball.

I think this is right, if not then let me know.

im no expert, but what if the balls were different shapes but same weight???

and do all markers affect the shape of the ball in the same way when firing???

 

[Fooey]

to be honest, to affect the distance enough for you to notice it you'd have compare a paintball with a tennis ball or a lead shot.

Actually, a heavier object (if it is the same size as the lighter one) will travel further. In order to achieve the same velocity, it needs more energy. If both objects are the same size, they will experience equal amounts of friction from headwind, etcetera. Friction can also be measured in energy. So if the heavier object travels at the same speed, it will have a greater amount of energy to push it along, but it runs into an equal amount of friction, thereby causing it to decelerate at a slower rate, therefore it will travel further. If this were to take place in a vacume, both objects will travel the same distance, because there is no friction.
The thing we're talking about is known as momentum.
In order to give you a simple example, I will use two cars.
Both cars are roughly the same size, but one is half again as heavy as the other.
If both cars are running at the same speed, and they drive into a brick wall, the heaviest one ofcourse has the better chance of going through the wall, simply because it needs a whole lot more counterenergy, in order to be brought to a stop.

Makes sense?

Thanks Buddha

thanks for sorting that one out mate, it's been a long time since my 'A' levels.

Buddha I think you are only partially correct. Yes object that weigh more will have greater energy behind them - and yes that means that a heavy object will fly farther than a lighter object.

However - if I remember my high school physics correctly the force of gravity on both objects is the same. Therefore 2 paintguns (cocker & angel) that are both aimed using the same angle from horizontal, will fire equal distance assuming that the muzzle velocity is the same.

Also in Robbos original post he was talking about on marker against the other shooting the same paint and using the same quality barrel. Take both an Angel and a Cocker shooting Diable Hellfire through the identical sized dye boomstick, with the same chrono velocity and both aimed at the same angle from horizontal. In slow single shots I will bet that there will be no visible difference in the accuracy & distance between the 2.

Where the supposed cocker (and the brick like shocker) accuracy comes from is from the fact that it fires from a closed bolt (therefore less recoil & movement when the paintball is still in the barrel) and also greater weight (heavier markers react less to any recoil from the bolt). The same can be seen when you compare real firearms - Olympic .22 cal. shooting is done with heavy target grade bolt action rifles. less moving parts & greater weight to combat even the slightest recoil that comes from a .22 cal. bullet.

Just some of my thoughts.

Hi Goose,

I was only responding to what Fooey said. I'm not getting into the 'this gun'll shoot better than that gun' debate.
What you say is correct. Gravitational pull is equal on both objects, therfore giving them equal amounts of airtime (for the laymen: it will take the same amount of time before the ball hits the ground). All that I meant with the heavier thing, is that it will suffer less from airfriction, which would normally mean that a heavier object will travel further.
So yeah, what you say is right. Both paintballs will travel equal distances. My post was actually not related to paintball at all, I was just explaining why Fooey's observation about heavier things travelling less was incorrect.
So please, view my post out of a paintballing context.

By the way, if someone would manufacture a paintball that is twice as heavy as a regular one, it would shoot further in your experiment, because it would suffer less from the gasses it has to pass through as soon as it leaves the barrel (this includes any atmospheric gasses, such as the air we breathe). Should we on the other hand, be able to conduct the same experiment in a vacume, both balls would travel equal distances (like I said earlier) because none of them would suffer from any friction.
This is all just theoretical banter, because there is no paintball that is twice as heavy as the other. Sure, there are some balls that are heavier than others, but the differences are so small, as to be ignored. Therefore the weight thing I discussed, should be seen outside of a paintballing context (as I said). I was only explaining the theory of momentum, which has very little to do with firing your marker (except for the bolt action thing you mentioned), and everything with running into bunkers

P.S. Goose, you should post more often. So far your posts have always been well informed, backed up by good arguments and therefore worthwhile reading.

Thanx Buddha, I try only to post stuff when there is something interesting to post, and I've also reached the same point Robbo has in regards to people taking debate & accuracy. There is too much crap sometimes on this board and I try not to contribute to it.

As far as everything we have discussed I uderstand your point now (and I did realize you where answering Fooey but I just wanted others to know) and as I said it has been so long since I have dealt with physics, I will bow to the Buddha and just say I'm too dumb to argue.

Anyway dude, have a good weekend and think about inventing some havier paintballs so we can longball people.

Well done Goose and Bud !!!

Hi Guys,
Since this is now getting technical with Goose and Budha finally applying the last nail to the coffin I made for the Paintball sceptics and ignoramuses, I will remind you of my first post when I began this attack, it was not in this thread but in the one entitled Harry (Chill).
I mentioned Isaac Newton and behind virtually all modern day practical science is this man Newton, he da man.
It is he who provides the knowledge (for those who are willing to listen) to cut down all this bull**** about paintball range and accuracy and in doing so, reveal how people can be so easily duped by their senses and by what they have 'heard'.
I'm glad I ain't a lone voice on this board when resorting to science to try and explain why something is just plain bull****.
I am sure there are many more of you guys out there apart from Goose and Budha whose input we could do with now and again to dispel a lot of **** we hear on this board from time to time, so let's hope we see more of you.
After all, the last thing you guys want is for me to keep chirping up all the time with the answers, you might begin to think I'm a big mouth know it all.....and I wouldn't want that now would I ?

In a perfect world bla bla bla

Nice Goose

It is basically back to the: one shot one kill.

What is the first thing that happens, when you shoot your marker ?

Think about that....

Dont give me the perfect ball and everything else the same... which are all your "open bolt" players excuses.

We are not living in a perfect world with perfect round "balls", but need to be able to give our "balls" the perfect playing conditions




Over and out.... and on my way to party
