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 combust
ING gasses to turn into combust
ED 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.
