Rockets cannot propel in space vacuum.

why do you keep posting the same shit over and over again

obviously you are wrong or the space station and every satellite in earths orbit would come crashing down

I can’t prove that rocket work in space.........but look space station and satellites lol

Okay Einstein WTF is " pressure gradient force."??

Go take the nozzle off a garden hose; hold it about three foot from the end ; turn on the water faucet ....What happens? the hose whips around and slaps the shit out of you. The water pressure exerts force on all sides of the hose except the opening. The unbalance of forces causes the hose to react. Now go to bed.

Dipshit

i take it evolutionists that said god is fake and the earth cant be flat to me on twitter still cant answer that question huh?

and they thought they were more qualified scientists than the boy genius who helped john titor

lol retards

Pelosi has a sweet set of tits on her. If I worked for her, I would call her Sugar-tits!

That isn't a fair or exact representation of a rocket.

Doesn't Canada have science classes in high school to explain how a rocket works?

They replaced that class with "how a manual can opener works".

So far only about 5 students have passed.

The rest dropped out after the first gruelling minute.

Rockets work in space every day you moron !

I believe they can. Here is the issue though. Most rocket take huge amounts of fuel to achieve escape velocity or to achieve orbit. Once they are travelling at these high velocities, the craft can only be nudged a little here or there, as it would take huge amounts of fuel to appreciably alter the trajectory and momentum they attained in their initial boost phases.

Assuming a craft could refuel in orbit or along its path to a destination in the solar system I see no reason why it could not propel itself in space. But like I said, this is not something that typically happens.

The craft are accelerated to a velocity and if they are an interplanetary craft they mostly just meander through paths that conserve their momentum or add slightly drawing into one gravity well or another along their paths. Propellant is used ever so slightly and sparingly along the way to make minute adjustments. Not much more.

Usually because he is pimping his own youtube channel. This time though he didn't post a video probably because he doesn't want to get banned again.

space is not a vacuum.... your first error in reasoning.

another attention getting Saturday thread...

Rockets and engines in space behave according to Isaac Newton's third law of motion: Every action produces an equal and opposite reaction. When a rocket shoots fuel out one end, this propels the rocket forward — no air is required.

Evidence of an equal and opposite force from gas movement due to pressure gradient force = none

not what that video shows.
The hose only moves further back when water directed back from the cup is hitting the hose. There are times when it is not hitting the hose but still the cup and the hose doesn't move more, specifically at 38 seconds.

The part with the pen is stupid and only exposes the ignorance of the maker of the video. the pen doesn't expel anything so it shouldn't move anywhere.

The part with the rocket in the vacuum chamber deceptively edits out the beginning where the rocket motor moves before the chamber is filled.

The part with the drone has it close enough to the cardboard to be experiencing ground effect which is why it rises with the cardboard and drops when it is taken away. Have it hovering in the middle of the room and put the cardboard more than a few inches away and it would have no effect.

so essentially you have multiple lies in your video.

Evidence showing no equal and opposite force from gas movement due to pressure gradient force = 1

Evidence showing and equal and opposite force from gas movement due to pressure gradient force =0

The cup demonstrates that fluids can bounce back creating thrust. Just because the cup was redirecting and missing the hose at certain points doesn’t mean anything . Air is all around, unlike the cup, redirects the water in the hose all the whole time.

The pen is a good demonstration. The top of the pen was expelled in the first demo. The second demo it hit the box so it didn’t come out the whole way.

The whole video shows that rockets cannot propel without resistance. The pressure has to build up in the chamber. The chamber is not in vacuum because you can see the smoke. Smoke=matter vacuum= absence of matter

Wtf do you think ground effect is,? gas being redirected from the ground proving that rocket push off external resistance

DOES TOO!

Study Newton's law about action/reaction, and then get back to us.

AGAIN, the hose only moves more when the cup directs water back that hits the hose. If the redirected water does not hit the hose then the hose does not move more. Right there that disproves your argument.


No, the pen is still a bad demo. Even if the top was expelled, and it is not clear that it is, then it is a very small mass compared to the rest and low momentum overall.


AGAIN, the part at the beginning is deceptively edited out that shows the rocket moving BEFORE the chamber is filled.


Propellers are not rockets and ground effect does not help your argument. Ground effect only works when the air hitting the ground comes back to hit the wing and keeps repeating. Similar to your deception with the hose and cup.


So still multiple lies and you're only adding more.

If rockets had to push against air then they would lose thrust the higher up they go. In reality, missiles have longer range and higher speed at higher altitudes. conservation of momentum is still a thing.

fail

space is not a vacuum

zero pressure does not equal vacuum

it takes negative pressure to create a vacuum

Your just grasping at straws. This is exactly what the atmosphere does. It redirects the fluid back towards the nozzle.

Vacuum is 0 pressure. Negative pressure simply refers to an area of low pressure where there is a pressure gradient.
