Again; whatever...

Read this definition of 'Physical Body' from wikipedia carefully please:

"A physical body or physical object is an identifiable collection of matter which may be more or less constrained to move together by translation or rotation in 3-D space".

Then bearing it in mind, answer this:

How many Bodies is a rocket (singular noun)?

By the wikipedia definition I only count One.

Then consider this, Newton's 3rd Law:

"To every action there is always an equal and opposite reaction: or the forces of two bodies on each other are always equal and are directed in opposite directions."

Note that it refers to Two Bodies.

But we have already seen that a rocket is only One body.

So; what is the other Body it creates force against in order to produce motion?

Any answers?


Oh, & let's not forget sceptimatic's questions that you all bailed out of answering; here they are again:

What kind of pressure is this supposed rocket fuel under when it's released and also what operates the supposed turbo pumps that also apparently pump it into the chamber and also how thick are the pipes that channel this fuel mix to the  supposed, combustion chamber?

Assume we are dealing with the fictional Saturn V.
You're allowed to answer whilst calling me names and such as long as you give me some answers.

Gutless bunch ain't you?

I await your shitpost non-responses with keen disgust; Inquisitive& sock-arul have already got theirs in; who's next!

Toodle-pip, Cowards!
Care to explain how the rocket pushes off air yet?

Since you brought it up:

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.
It's clear to a child that Santa Clause brings presents at Christmas time.  What's your point?

The combustED gases may trail off; but the combustING gases stay with the rocket at all times.
How long does it take for combustING gasses to turn into combustED gasses?

Again; a child can tell the difference between SMOKE & FIRE.
Fire is a chemical reaction and smoke is a byproduct of incomplete combustion. 

But you lot can not...

Sure I can, but apparently you can't tell the difference between combustion gasses and smoke.  LOX/LH2 rockets don't produce smoke, they produce steam water.

LOL!!!
Yes, your understanding of rockets is quite funny, in a sad, pathetic sort of way.

As previously stated, the 'man on skateboard' FALSE rocketry analogy is clearly more suited to describing the recoil from a gun.
Actually, it can be both.  Then again, we all know what a problem you have with duality.

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?
Yes, simple things for simple minds.

But a Rocket is not a gun, nor does it fire cannon balls;
Actually, it sorta is.  The main difference is that, in a rocket, the cannon balls are microscopic combustion gas particles.

... 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.
How does a rocket grab and push off the air?

Thus, he will be interacting directly with the mass of the medium upon which he moves.
Just out of curiosity, how much air, by volume, must a 10 kg rocket interact with in order to accelerate to 10 m/s in 2 seconds at sea level?

Just like a rocket exhaust does with the atmosphere.
If the rocket's exhaust is interacting with the atmosphere, then what is the rocket interacting with?  Is the atmosphere pushing the exhaust back into the combustion chamber in order to push the rocket?

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.
Ooooookay.

& the same goes for a rocket & its exhaust.
See, that's why it's a good thing that you're in construction and not in aerospace.  Did you know that a sail boat can move faster than the air pushing it?
America’s Cup: how the yachts go faster than the wind

The victory by Sir Ben Ainslie and his Oracle Team USA in the America's Cup is being ranked as one of the most astonishing comebacks of all time. The Telegraph’s science correspondent Richard Gray examines the technology that allows the boats to travel at up to three times the speed of the wind.

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

 A child can see it.
Would you trust a child to build your house?  After all, Newton's third is used all over the place in construction.

Yet you cannot.

Why?
Because sometimes you need to look beyond what a child can see.

Who cares?
Obviously you do, otherwise you wouldn't be here, would you?

But if you disagree, please provide easily-verifiable evidence & simple experiments to support your case.
No problem.  Fire off a bottle rocket in a vacuum chamber and see what happens.

You won't; because you can't; because it is impossible...
I did because it's very possible.

Oh, there have been lots of answers provided.  You just keep ignoring them and keep shitspamming the same questions.

Now; read this definition of 'Physical Body' from wikipedia carefully please:

"A physical body or physical object is an identifiable collection of matter which may be more or less constrained to move together by translation or rotation in 3-D space".

Then bearing it in mind, answer this:

How many Bodies is a rocket (singular noun)?

By the wikipedia definition I only count One.
As has already been mentioned (and promptly ignored) the combustion gasses being pushed out the back of the rocket engine are not constrained to move with the rest of the rocket, the rocket is one physical body and the exhaust gasses produced by burning the fuel and oxidizer carried by the rocket are another physical body.

Then consider this, Newton's 3rd Law:

"To every action there is always an equal and opposite reaction: or the forces of two bodies on each other are always equal and are directed in opposite directions."

Note that it refers to Two Bodies.
Yup.  The rocket and the combustion gasses.

But we have already seen that a rocket is only One body.
And the exhaust gasses makes Two.

So; what is the other Body it creates force against in order to produce motion?
I'll give you a hint; what do you get when you burn lots of fuel and oxidizer in a confined space with a small opening at one end?

Any answers?
Yes, but none that you'll accept.

And again:

1) The rocket, it's components and the fuel and oxidiser in storage tanks are constrained to move together and are therefore one object. Any force will accelerate everything.

2) Any fuel and oxidiser that is in the combustion chamber is NOT constrained to move with the rocket. Therefore fuel and oxidiser in the combustion chamber can be treated as a separate object.

3) these two separate objects can interact and according to newtons third can push and pull each other.

And to clarify the point you think you have jumped on:

The statement to 'push off' something clearly implies that physical contact is required. The statement of newtons third stating push or pull merely uses those words in context of a force away or towards the object. As I mentioned Magnets are perfectly capable of interacting at a distance. Therefore they can push or pull but they do not push off.

Now bore off.

Oh; look:

2) Any fuel and oxidiser that is in the combustion chamber is NOT constrained to move with the rocket. Therefore fuel and oxidiser in the combustion chamber can be treated as a sepsrate object.

Yes I have, repeatedly & at length on several different threads.

Pretending I have not won't change that.

Just like Pretending you're a scientist won't change how little you know about basic physical laws.

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...

Being completely ignorant on rockets and technical thingos like that I need a little unbiased advice.  Papa Legba argues till he is black and blue in the face (well his language is certainly heading that way) that rockets cannot work in a vacuum, but that ignorant mob at MIT seem to think that not only do they work in a vacuum by not only have less drag (obvious no air resistance), but actually have more static thrust as well!
There is of course from that publication quoted many times here: http://web.mit.edu/16.unified/www/SPRING/propulsion/Propulsion.pdf
In that on page 10 I believe they get a static thrust equation for a rocket:
T = ṁue + Ae (pe – po)
Where:
ṁ = momentum integral
ue = exhaust velocity
pe = exhaust pressure
po = ambient pressure

Maybe some intelligent person here can explain it to me.  It sure seems that the rocket should work better in a vacuum.  Maybe MIT is wrong.
BTW, I don't believe Newton's 3rd law came into it, you know the one Papa Legba insists we write as Newton did as:
"Lex III: Actioni contrariam semper et æqualem esse reactionem: sive corporum duorum actiones in se mutuo semper esse æquales et in partes contrarias dirigi."
The derivation of that equation was from his 2nd law, the one Newton wrote as:
"Lex II: Mutationem motus proportionalem esse vi motrici impressae, et fieri secundum lineam rectam qua vis illa imprimitur."
Papa can translate.

*Yawn!*

W=pv.

When p=0, W=0.

Only equation needed.

Unless you allow yourself to be baffled by bullshit.

Back to trolling youtubes for you now, 'rab downunder' & pals.

I wonder who'll grab top spot on the next page?

Let's find out...


I got Trolled & Shilled at the CIA Troll/Shill Society and now I feel EPIC!!!

Applies to all.

So?

You still haven't refuted my argument. Telling....

Yes I have, repeatedly & at length on several different threads.

Pretending I have not won't change that.

Just like Pretending you're a scientist won't change how little you know about basic physical laws.

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.

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. This validates rockets as being consistent with Newton's 3rd.
Never attribute to malice that which can be explained by ignorance or stupidity.

what that should prove?
oh no, i get it now, u keep ignoring REAL physics cause u're a troll and u don't know how to keep trolling when the truth is clear.

good day cindy
