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
Okay keep telling yourself that
Or they have on board oxidizer.
Resistance is required
Several practical liquid oxidizers (liquid oxygen, nitrogen tetroxide, and hydrogen peroxide) are available which have better specific impulse than the ammonium perchlorate used in most solid rockets when paired with suitable fuels.
It does not work in a Vacuum. Nothing to push against.
you don't
need
anything
to push against
When tested it did not work.
that gif sheeple spams shows the rocket moving when it ignites
it jiggles a bit but the apparatus that the gif shows is not meant to move so the rocket didn't continue moving
but it did move a tad
Till the tank was filled with exhaust the rocket did not move.
Someone tell the ISS to stop firing for orbital corrections.
as soon as it ignited, it moved
before gas started spilling out
It did
Then it had that exhaust to push against.
here's an ISS reboost video
Nope. It took a second or so to get enough exhaust to make it not a vacuum.
n a rocket engine , fuel and a source of oxygen, called an oxidizer, are mixed and exploded in a combustion chamber. The combustion produces hot exhaust which is passed through a nozzle to accelerate the flow and produce thrust.
You need something to push against
No, you don’t
forces always act in equal but opposite pairs
you don't need something specifically to *push* against
that's a misinterpretation of the quote and law
If you stand on a skateboard and throw a bowling ball forward, that force will push you and the skateboard back. However, because your weight on the skateboard is heavier than that of the bowling ball, you won't move as far.
an experiment that no air is needed
Yep
that's a better experiment that explains the law better
Always love those fake videos. Just as valid as the earlier one whim him swimming around the ISS.
"push" is not literally something that's pushing you
I always love claims without evidence....
hope that helps clears things up
here's a 25 min tour of the ISS
I can link a 50 min one if you want
