No, they are different.

rocket uses propellant to push off gas

@tripolarbear Let's have a look

with nothing to push off, rocket doesn't move

A feather and a rocket are different in their composition and structure.

if you want evidence on why rockets work just fire a gun you live in the us right?

they both use air to move

and just change the density of the projectile

A feather is made up of a bunch of loose parts while a rocket is one solid object.

eg a heavyier bullet

running fan is using air to push a feather, move it

@tripolarbear So why isn't it moving?

rocket uses air to push itself, to move it

because its anchored

in a vacuum neither moves

you cant have your rocket flying around your vacuum chamber can you?

that image I ~~showed~~ mentioned above is inconcslusive because of the parameters of it

@^Kevin^ use a bullet with a weight then compare the recoil to a bullet that weighs more but has the same velocity

different recoil

Could you people listen? I've tried saying that when the gases in a rocket evacuate the chamber that they are in, the leave out through a cup shaped nozzle. The gas accelerates because the diameter of the nozzle changes, resulting in a force. Newton's Third Law, the opposite force is being applied to the cup of the nozzle

they dont believe in newtons third law

lets not overcomplicate something already complicated by bringing guns into it

rockets "push" off air apparently

@tripolarbear Only when it suits them it seems

guns wouldn't work in a vacuum because the gunpowder wouldn't ignite without oxygen in the air

The gas is pushing on the rocket, the gas isn't pushing off of the air

you'd need a gun that would work underwater for it to work

but in nz we dont worry about people carrying around hand guns and suicides are less?

like a spear gun

its smokeless powder

that has no relevance to vacuums and rockets/fans/feathers

gun ownership is directly related to suicide succesfulness

@^Kevin^ Alright, what about what I said then

gun usage*

you cannot throw yourself forward with your own hand

you have to push off something

or walk

or swim

@tripolarbear Care to explain please why the rocket does not move but mister flappy however does and moves in the WRONG DIRECTION ?

Yes, and the gas is pushing on the rocket as it is leaving the fuel chamber.

ew gif compression

MISTER FLAPPY 😂

i cant tell wtf that is

rockets cannot push themselves forward with nothing to push off of

yeah they can

its called newtons third law

look it up

Well here's the video you just sent me

720p

and pushing off themselves doesn't help

No, Kevin. The gas is pushing on the rocket as it is leaving its tank.

So please look at the orb closest to the camera and explain mister flappy please @tripolarbear

if you push off yourself, where do you go?

you don't move

you spin

your not moving

no linear motion no

Kevin, the rocket is NOT pushing off of itself.

gasses from the rocket?

but angular motion yes

you don't spin by pushing off yourself

you spin by pushing off something near you to create a spin

Are you telling me I can't make myself spin?

KEVIN, the rocket is NOT pushing off of itself

If I was in a vacuum chamber and I switched on an angle grinder I reckon it would still spin

The gases leaving the rocket are applying a force to the rocket to propel it forward

but no linear motion no

rockets don't work in vacuums because the stuff its expelling called propellant needs something to propel off of

if you take a boat and remove it from water

propellors can spin on an airplane when you fly too high but the propellors are doing nothing, no forwards propulsion

No, Kevin it doesn't. The gas is combusting and expanding.

its not going to move , its out of the element it was designed to move in

no amount of newtonian laws is going to make a boat move when its not in water

It is being forced out because of this.

Feminism is gae lel

same with rockets, rockets don't work when they are out of the medium they were created to move in

Well if you put the boat onto some ice and you sanded down the hull and you removed all drag and you spun the propellor really fast i reckon you could make the boat move forwards very very slowly

rocket without air is a boat without water

Kevin, are you reading what I'm typing?

combustian works differently in a vacuum

its less explosive

either way I think a rocket in a partial pressure chamber isn't going to produce any meaningful thrust

more like sputters

The combustion process isn't occurring in a vaccuum it's occurring in fuel tankks

doesn't matter

They are separated off from the vacuum

yes but if you fill the combustion chamber with fuel and oxidizer and you burn it, there's still enough pressure per second for a reaction to occur

however the reaction has no medium to push off

once its already combusted then its lost its explosive force

The fuel and the oxidizer are separated until they need to be mixed

or in the case of solid rocket motors the fuel and oxidizer are pre-mixed

That is why Sheeple is pointing out to you why Mr. Flappy isn’t going the other way. It should be if the Rocket were creating force to push off of.

it doesn't matter how you slice it, the rocket doesn't work in a vacuum

and pushing that it does is the same thing as pushing the globe lie

it doesn't work and you believing it works doesn't make it so

Communism is superior

in a way im kinda glad you guys dont have jobs in engineering
