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

2019-07-16 02:29:54 UTC  

Okay keep telling yourself that

2019-07-16 02:29:57 UTC  

Or they have on board oxidizer.

2019-07-16 02:30:04 UTC  

Resistance is required

2019-07-16 02:30:12 UTC  

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.

2019-07-16 02:30:16 UTC  

you don't

2019-07-16 02:30:17 UTC  

need

2019-07-16 02:30:18 UTC  

anything

2019-07-16 02:30:19 UTC  

to push against

2019-07-16 02:30:30 UTC  

When tested it did not work.

2019-07-16 02:30:45 UTC  

that gif sheeple spams shows the rocket moving when it ignites

2019-07-16 02:30:58 UTC  

it jiggles a bit but the apparatus that the gif shows is not meant to move so the rocket didn't continue moving

2019-07-16 02:31:06 UTC  

but it did move a tad

2019-07-16 02:31:07 UTC  

Till the tank was filled with exhaust the rocket did not move.

2019-07-16 02:31:14 UTC  

Someone tell the ISS to stop firing for orbital corrections.

2019-07-16 02:31:19 UTC  

as soon as it ignited, it moved

2019-07-16 02:31:22 UTC  

before gas started spilling out

2019-07-16 02:31:25 UTC  

It did

2019-07-16 02:31:34 UTC  

Then it had that exhaust to push against.

2019-07-16 02:31:49 UTC  

here's an ISS reboost video

2019-07-16 02:32:03 UTC  

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.

2019-07-16 02:32:34 UTC  

You need something to push against

2019-07-16 02:32:47 UTC  

No, you don’t

2019-07-16 02:32:54 UTC  

forces always act in equal but opposite pairs

2019-07-16 02:33:01 UTC  

you don't need something specifically to *push* against

2019-07-16 02:33:18 UTC  

that's a misinterpretation of the quote and law

2019-07-16 02:33:52 UTC  

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.

2019-07-16 02:33:57 UTC  

an experiment that no air is needed

2019-07-16 02:33:59 UTC  

Yep

2019-07-16 02:34:14 UTC  

that's a better experiment that explains the law better

2019-07-16 02:34:24 UTC  

Always love those fake videos. Just as valid as the earlier one whim him swimming around the ISS.

2019-07-16 02:34:25 UTC  

"push" is not literally something that's pushing you

2019-07-16 02:34:42 UTC  

I always love claims without evidence....

2019-07-16 02:34:47 UTC  

hope that helps clears things up

2019-07-16 02:35:03 UTC  

here's a 25 min tour of the ISS

2019-07-16 02:35:07 UTC  

I can link a 50 min one if you want
