Umm... You do realize that friction is the resistance to movement, don't you?
Yes and you also understand that for it to be a resistance to movement, it also has to be an energy to start movement, which equates to what everything always equates to. Every action (energy/friction) creates an EQUAL and OPPOSITE reaction (resistance/friction).
Do you mean like when hot gasses push against the combustion chamber wall in a rocket engine?
That and every other happening in a medium.
Try not to use my answer as a means of proving rocket propulsion without an external atmospheric resistance, please, otherwise I'll have to come back and explain what's going on and it could extend to many pages of back and forth tit for tat.
Please do, and we can then point out how badly wrong you are.
Your problem is that you cannot point out how badly wrong I am. You can spend all your time telling me I'm wrong and following a pattern given to you by mainstream science books that tell you to accept that rockets work in a way that sounds logical when told in it's raw term, but is soon found out when common sense and logic come to the fore about atmosphere.
One thing I will give those in mainstream indoctrinated science circles is, they pushed a clever ruse out to cater for rockets in vacuums and knew that most people would never be able to test out whether it was true or not, due to nobody having a sufficient testing area for a rocket.
They use second rate actors to calm those people down who do not buy into the trash by the pretence of testing out so called issues with objects in supposed vacuum chambers and declaring them BUSTED as per normal, each time, making sure they twist up their faces and shout, " in your face, conspiracy theorists", or " get over it, conspiracy theorists."
Any other query that has nothing to do with the major ruses, they simply say, "myth busted" or " myth confirmed" or " plausible."
Mention any conspiracy and they go into a frenzy. It's comical to watch them do this because it tells me just how far people will go to play a part in acting, in the full knowledge that they are acting out something that is deliberately doctored to fit a criteria.
I remember watching Brian Cox and the little supposed crew who man the so called huge vacuum chamber at NASA and they done the bowling ball and feather trick. Something which has apparently been done so many times before so as to become the norm and no big deal at the outcome.
Not Brian Cox and his little vacuum chamber team. they were looking at each other all excited as if a frigging clanger has materialised out of thin air and whistled to them. They were literally pretending to look shocked as if they'd never seen a bowling ball and feather, fall in a vacuum.
Maybe it's because they haven't, eh? but they'd like good old naive Joe public to believe it, as well as the super naive budding scientists who will literally piss their own pants at the sight before them.
Let's make something clear. If people can use their minds to see the world for the simplicity it actually is and can push aside the mind numbing bullshit space science clap trap and all what goes with it...including a frigging warped ball for an Earth, then they will literally start to feel their brains actually switch on into logical mode.
From that point on, as long as peer pressure doesn't infest the workings of that brain, then people are going to start seeing things in a totally different light, seriously.
Hanging onto equations and complete utter un-provable bullshit that answers nothing realistic will literally warp any persons brain to the point of meltdown, rendering that person about as much use as a legless mute, scrapyard guard dog.
