i did for a bit
one guy with a MSc > 100% of rocket physicists
just showed a disturbing portrait of a man
this guy has a master's degree in technical physics
let me see
he's telling you it has nothign to push off of, it won't work
and hes wrong
because he apparently doesnt understand rockets
well, the link is up above
lets read newtons third law by quote shall we?
For every action, there is an equal and opposite reaction.
maybe we should watch this video and see if he address it
goopy
srry
so if I flap my arms in a vacuum, am I going anywhere?
nope
no medium to propel you up
if I take an oxygen tank in a vacuum and start releasing gas, am I going to move anywhere?
if you let the gas out at a very fast speed and a very high pressure, you're going to fall backwards from the force of the gas ejecting out the tank
if you let it drizzle out nope
have you tried it yourself or are you just saying so
you might get thrust but I don't think so, not significant amount
depending on how fast the oxygen comes out ya you might not get much, but you still get it
on the plus side any thrust would be better in a vacuum though
yes it would
because you don't need alot of thrust to move, unlike atmosphere
no air resistance
indeed
you still have the problem of pushing the amount of mass foward
in a vacuum with no air resistance would make it easier
true
but the rocket has to get there first
so it trudges on through the atmosphere
still amount of mass matters because it limits how much thrust you need to generate to move the entire mass, and stop it
the more mass the more thrust
suffice it to say that although it might function some, it wouldn't work enough to land on the moon and take off again, land back on earth
let me find a fun fact real quick
the more mass means the more thrust you need to move it
even in a vacuum
All Apollo missions carried and used around 5,625,000 pounds of propellant in all three modules and the Saturn V launch vehicle. This is for the whole trip, with the greatest amounts being used in the first minutes [to achieve orbital velocity] by the Saturn V rocket.
