the rocket keep on accelerating since there's a force (thrust) acting on it and less and less air resistance

The maximum speed of the rocket is limited by the maximum speed of its exhaust, in accordance with Newton 3.

Look:

The Newtonian definition of a Force is: 'A push or pull on an object as a result of its interaction with another object'.

So, if Object One is pushing or pulling on Object Two at the speed of 9,000 mph, there is no way that Object two can exceed that speed.

Thus, it can only accelerate UP TO its maximum speed & thereafter it can accelerate no more.

Simple, eh?

I know it's your job to make it un-simple...

But it just is.

Toodle-pip, Fido!

The maximum speed of a rocket is set by the maximum speed of its exhaust.

Thus, it can only accelerate UP TO its maximum speed & thereafter it can accelerate no more.

I do not care what kind of Harry Potter mathe-magical mumbo-jumbo you hurl at me.

I will just keep re-posting the above no matter what.

It rubs my bullshit into its brain, or else it gets the hose again... It rubs my bullshit into its brain, or else it gets the hose again!

Sorry, Buffalo Bill, but as I am not confined to your skinning-pit, I have no need to defer to your psychotic brainwashing.

Now read this & STFU:

(try moving a wall, tough guy).

You could not have picked a worse person to say this to.

I have built, demolished, re-built, re-demolished, moved, removed, stabilised, destabilised, altered, re-altered, renovated, re-renovated, and generally done everything possible to, more Walls than you could ever shake a stick at...

None of which makes me a 'tough guy' at all.

It just makes me good at my job.

Because my job is doing Real things in the Real world using Real physical principles...

Whereas your job seems to be playing with words & numbers in order to make your favourite sci-fi fantasies possible.

Funny enough, my job IS to play with words and numbers.

Look at me, Im Mr CantGoogleToSaveHisLife, look at me making up definitions!: 'A push or pull on an object as a result of its interaction with another object', then whatever speed Object One is pushing on Object two must set the upper limit for the speed of Object Two's motion in the opposite direction.

The rest of my post is pitiful garbage & is to be ignored.

And, yes, an object can go much faster than its reaction speed, because the only important thing is the relative speed between both objects, and while acording to the rocket the exhaust is going down, in fact it is going in the same direction of the rocket (in a vacuum), just slower. Simply change the POV to the rocket.

The leaf thing is very very lame.... Leaf is moved by air resistance, rocket is propelled thanks to conservation of momentum...

But hey, if you think we should accept your mathematical abstractions over all the evidence of our senses, then good for you, Fido!

Human senses are extremely limited and we have moved past their limits in our study of the world a loooooong time ago.

That is the single most insane post I have ever read here.

No wonder you all believe this sci-fi fantasy bullshit is Reality.

That you do not understand that is a testament to how pathetic your debates are here.

Still waiting an answer about the elevator

As for your lift schtick, you are sneakily introducing a THIRD force into a basic Newton 3 scenario consisting of only TWO.

Really, you are shameless!

Please go away and either return with some physical evidence for your position or leave us all alone.

Much more meaningful. Our sense can easily be tricked, math doesn't lie.

As far as the elevator the question remains.
U want only action reaction forces, ok. Remove gravity. If I'm in an elevator accelerating, can I or cannot I jump?
