*Yawn!*

W=pv.

When p=0, W=0.

Only equation needed.

No you did not address the point about a rocket being one object and the fuel/oxidiser/exhaust in the combustion chamber being another object.

Yes I did, Liar; months ago.

Look:

A rocket & its exhaust are NOT Object A & Object B in a Newton 3 scenario; it is clear to a child that they both move together & are part of the same thing.

The combustED gases may trail off; but the combustING gases stay with the rocket at all times.

Again; a child can tell the difference between SMOKE & FIRE.

But you lot can not...

LOL!!!

As previously stated, the 'man on skateboard' FALSE rocketry analogy is clearly more suited to describing the recoil from a gun.

Thus, the ball (Object A), represents the projectile; the skateboard (Object B) represents the gun; & the man, in THRUSTING or APPLYING PRESSURE/FORCE upon the ball represents the propulsive charge (i.e. gunpowder or such).

See? Simple eh?

But a Rocket is not a gun, nor does it fire cannon balls; so let me fix your dumb analogy so it is more fitting to rocket propulsion.

Instead of having the man on his skateboard throw a ball, simply have him reach down & begin pushing himself backwards along the ground with his hands.

Thus, he will be interacting directly with the mass of the medium upon which he moves.

Just like a rocket exhaust does with the atmosphere.

Just like a rowing boat does with the water.

Just like the wheels of a car do with the road.

It will also be seen from my example that the velocity of the man on skateboard can NEVER exceed the velocity at which his arms are pushing on the ground.

Same goes for the boat & its oars.

Same goes for a car & its wheels.

& the same goes for a rocket & its exhaust.

It is all VERY simple, you know; Newton's 3rd is.

 A child can see it.

Yet you cannot.

Why?

Who cares?

But if you disagree, please provide easily-verifiable evidence & simple experiments to support your case.


Must suck to be you right now, Walter Mitty.


what that should prove?

That a gas-powered rocket can do no work in a vacuum...

To anyone who's not a retarded troll-entity.


What happened to F=MA?  Don't we need that one too?

I though your 'thrust equation' used F=m*v?

Make your minds up, shpayze-tards...

AHAHAHAHAHAHHAHAHAHAHAHAHA
Cindy, u're butchering physics in order to prove u're nonsense statement.

ps F is NOT m*v cause MASS FLOW is NOT MASS, mass flow is dm/dt.
mass flow is the time derivative of the mass.

so in case of rocket,
 or in any case in which propulsion is given thanks to an accelerated  fluid, thrust is more conveniently expressed as T=mass flow*velocity

pps work can also be expressed as W=force*displacement, don't u know?

i'm curious what are u gonna invent now?
but wait a second, weren't u trolling youtubers? what a busy life u've got cindy.

Papa Legba is 100% correct and most of these people know it and that's why they're trying like hell to batter him into submission.

When they're exhausted they pull out the bullying card and ask for bans by complaining to the mods which gets the desired result and the mods ban Papa Legba.

Cheers, Good hoppy, but to be honest it's fun anyway.

You gotta have a very thick skin & very low tolerance for Liars in my line of work, so all their shenanigans are water off a duck's back.

I'm glad to have confirmation that others see all the sock-ing going on, though; I don't care if the Derfers do it or not, frankly, just as long as neutrals know it's happening.

Anyhoo; back to the Fight!

Wonder who's chucked a shitpost in whilst I was writing this?

Oh, look - it's luckyfred, who I quoted as his sock-puppet tomfi for an entire day a few pages back without his dumb troll self even noticing until I rubbed it in his dumb troll face...

What's he got to say, I wonder?

AHAHAHAHAHAHHAHAHAHAHAHAHA

Yeah; that & a bunch of other bullshit.

The formula for work done by a gas is: Work = pressure x change in volume.

How will that pan out when pressure = zero, as it must in a vacuum?

Not too well I'd say...

And I just refuted that point by point on the previous page.

Again. 

Big surprise.

Mass * velocity = momentum, which must be conserved in a rocket.

Her's the post where I finally woke luckyfred/tomfi up to the fact he'd been answeing to his sock-puppet name for two whole pages:

am I a loser cause I've said something wrong?

No; it's a bit more obvious than that.

But at least you've admitted you ARE a Loser...

That's a start!

Now the healing process can begin.

It's all back on pages 196-198 of this thread for those who want a good laugh; I was pissing myself every time the dumb troll replied...

But I'm sure he'll now claim he knew I was doing it all along; that, I suggest would be a Lie, from a proven Liar.

Here you go, neutral readers & assorted sock-puppet disinfo entities; just in case you missed it, this is the post gibbering madman sock-arul found so very upsetting that it threw him into a full-blown seizure:

Rockets work by creating a pressure differential between themselves & the medium through which they move.

When that medium is removed - as in the case of a vacuum - then rockets cannot work.

This is absolutely elemental stuff; yet you will never, ever grasp it...

I leave the reason for your continued denials & ignorance up to neutral readers to deduce for themselves.

I have an inkling that anything the troll-things hate so very much must be worth a second look, eh?

They're not the cleverest of people, as well as being extremely poor Liars indeed...

The guy hasn't got a single part correct yet.

Like you got this 'correct', Walt the Science-pretender?

You come nowhere near winning that debate, in fact you got destroyed.

You do not need something to push off to move. You only need to develop a force on a mass. This is why you don't understand Newtons 3rd, or even 1st and 2nd.

Who cares what the origin of the word space is. It doesn't change what is present and what its properties are.

& here is my original reply, showing that I pointed out your schoolboy error at the time:

LOL!!!

Here is how ignorant mainframes, & the rest of you cultists, are on Newton's laws:

You do not need something to push off to move. You only need to develop a force on a mass.

But how does www.thephysicsclassroom.com describe a 'force' in its section on Newton's laws?

'A force is a push or a pull that acts upon an object as a result of its interaction with another object.'

So; 'to develop a force on a mass' IS THE SAME THING AS 'to develop a push on a mass'.

You really are engaged in a War on Science, ain't you?

And so is illiterate gibbering madman #2 luckyfred/tomfi:

ahahahahahahahahahahahah

if anything atmospheric pressure is a penalty, rockets work better in vacuum

Right; and Free Expansion does not exist?

Only the physics you want to does?

Try telling Newton, Joule & Thomson that; they may disagree...

Finally; this reasoned debate speaks for itself:

Poopoo Looser can also put sentence structure on the list of things that he doesn't know.

LOL

That explains alot.  He doesn't know the difference between a question and a statement.

LOL

That must be why he has such a hard time with more complicated tasks.

LOL

He probably still has him mommy tying his shoes.

Oh dear...

Now; read this, neutrals - the trolls Really don't want you to, so there must be something in it:

Rockets work by creating a pressure differential between themselves & the medium through which they move.

When that medium is removed - as in the case of a vacuum - then rockets cannot work.

This is absolutely elemental stuff; yet you will never, ever grasp it...

I leave the reason for your continued denials & ignorance up to neutral readers to deduce for themselves.

Toodle-pip, raving nutters; I'm sure every neutral looking in will be swayed by the calm, reasoned nature of your argumentation...
