It depends upon how much fuel is behind it, among other things.
Reaction forces are "stronger" in that as long as you supply fuel they can continue indefinitely and therfore can produce a greater acceleration in the long run.
QuoteIt depends upon how much fuel is behind it, among other things.Assume that both have exactly the same amount of fuel, (take gun powder for example) and an identical load to carry. QuoteReaction forces are "stronger" in that as long as you supply fuel they can continue indefinitely and therfore can produce a greater acceleration in the long run.Absolutely, this seems to be at least half of the answer. Look at the facts relating to the supergun. It was 510 feet long (that is not an exaggeration) the breech was more than a metre thick steel, it was loaded with half a ton of propellant and this was supplemented by charges being placed at stages down the length of the barrel that could add added impetus to the 500 lb projectile and the most that it could do with all this was to lob the thing a distance of a 1000 kms. A tiny missile, only 25ft. long and weighing about a ton and a half and using the same amount of propellant could propel the same load and a little bigger one could put it into orbit. Moral of the story don't knock reaction forces. OK! there maybe some comment on this but there is really no, comparison, think of how much the supergun weighed, look at the length of the barrel, the amount of propellant, the thickness of the breech, jeez. Then there is the question of the efficiency with which the fuel is used, right! McQueen
'Powerful' is a vague term - "power' is rate of doing work and I don't think that is what you mean. If you just mean 'force, then I could push over a house with a simple hydraulic piston much more easily than using a jet engine.
Anyway, I don't think that, using the same amount of propellant you could send the same load to a greater height with a rocket instead of a gun; it's not an easy thing to compute however.The formula to compute a rocket's push is:
The problem here is that you are not comparing like with like..
I ask again. Do you mean power, do you mean force, do you mean energy or do you mean efficiency in your comparison? The assessment, in each case may be different. I can't deal in specifics until I know what you mean by your original statement / question.
Do you see many IC aeroplanes? Why would that be?
Look outside - do you see any jet cars? Why would that be?
