IN A ROCKET SYSTEM, THE FUEL IS OBJECT B

Has anyone brought up the fact that although free expansion does not do any woro, that the combustion of fuel most definitely does and that that is the source of energy for the system?

You contradict one another, as usual.

Stop wasting my time posting more bullshit to cover up other bullshitter's bullshit.

NO WORK IS DONE ON THE SYSTEM.

It does not get any plainer than that.


Now; here is a post relating to the OP:

1) Object A = cannon.

2) Propellant = P.

3) Object B = cannon ball.

Propellant P sits between Objects A & B.

When Propellant P expands between them, Objects A & B are thrust apart & motion is produced.

Simple.


However, with a Rocket:

1) Object A = Rocket.

2) Propellant = P

3) Object B = ?

There is clearly no visible Object B in the rocket example.

But we know that, for Motion to be produced, Propellant P MUST expand between Two distinct Masses.

So; what non-visible Mass could replace the cannonball as Object B?

The only choice is the enormous, but non-visible Mass of the atmosphere.


Thus we get:

1) Object A = Rocket.

2) Propellant = P.

3) Object B = Atmosphere.

And motion can be produced.

Of course, when the atmosphere is not present - as in the vacuum of space - no motion can be produced.

Not that hard to understand, is it?

Unless it is your job to not understand it...

In which case: Carry On Lying! (with a bit of wiki-vandalism & invisible retro-editing chucked in)

Posting the same crap over and over won't make it gold. You still have crap.

Prove that a gas can even exist in a vacuum before suggesting it can 'combust'.

Good luck finding physical laws to support such nonsense!

For the millionth time, you can flow more into a chamber than out of it. Prove that air compressors don't exist.

What do you suppose is happening to the gas before the closed system reaches equilibrium?  Unbalanced forces in the form of a pressure gradient, perhaps?

If what you describe, and how you propose a rocket works, were true then the Joule free expansion experiment equipment would be forced sideways as the pressures equalised.

How do you know that it doesn't?  Have you actually witnessed a Joule free expansion experiment?

Look at YOUR diagram:



Why does the part marked gas NOT move AT ALL when the valve is opened?

Because it's physically connected to the part marked vacuum. 

According to YOUR half-baked ideas it SHOULD.

But it DOES NOT.

BECAUSE NO WORK IS DONE ON THE SYSTEM AT ALL.

BECAUSE IT'S A CLOSED SYSTEM.

IS THAT CLEAR ENOUGH FOR YOU?

Yes, it's quite clear that you haven't learned the difference between a closed system and an open system.

NOW STOP WASTING MY TIME!

I have no control over how you spend your time.  If you feel that your time is being wasted, then it's your fault, not mine.

Oh, and let's have another look at this, you disgusting little wretch:

Every law of physics says that you're an idiot who should never reproduce.

Yeah; that's about your level, Hypnotoad...

As if Saint Papa Legba hasn't said far worse.

As low as it's possible to get.

Pot, meet kettle.

As if Saint Papa Legba hasn't said far worse.

I haven't actually; what you said is the oldest Curse known to mankind.

I have lived in places where, if you said it to a man about his cow, he would never talk to you again.

And if you said it of his wife, he would kill you.

The source of this Voodoo Curse in the internet age is the JREF forum, a disgusting place named after a homosexual paedophile & blatant satanist.

Good to know where you learned your tricks, markjo.

But, again, generally speaking: STOP WASTING MY TIME WITH BULLSHIT.

Deaf dick?

Looks like Papa Legba is a dead man.

For God's sake don't reproduce.

The world doesn't need any more Hypnotoads...

Whatever. 

BTW, have you learned the difference between an open system and a closed system yet?

I'll give you a hint, a rocket is an example of one of them and a Joule free expansion experiment the other.

Blah, blah, lie, blah, lie, blah, bullshit, lie, blah, strawman, lie, blah...

Trained you well at JREF didn't they?

How's it feel to have a man like James Randi as a mentor?

A pain in the butt in the most literal sense possible, I'd imagine...

I can't believe you idiots are still arguing the same point that you have been arguing for over 200 pages spanning 3 different threads!  You guys are a glutton for punishment.

As usual, the thread generates a bunch of complaints clogging up my email and devolves into name calling and spam. 

So, as usual:

Momentum, conservation of.
The end.
Turn off the lights and lock the thread.
