Power = Force x Acceleration
Power = Force x velocity
Force = mass x acceleration
Awesome photo: incredible what some PBAN rubber, aluminium fuel and oxidiser does! (and some hydrogen and LOX, but you can barely see the faint SSME plumes…) :o
thanks for the help. Is there a formula for Impulse?
there is a formula for everything in physics.
resultent force X change in time= impulse, so
FT=p the units are kgm/s
thanks for replying “on the impulse” - so to speak (lame, sorry)
Beautiful plume. Rocket plumes, explosives and supersonic craft are to reason why I am studying shockwaves now.
Be careful when applying these formulas though, they are specific derivations with assumptions. (Particularly with your rocket).
Force = d/dt Momentum
Power = d/dt Work
Impulse = integral of force with respect to time
Note: these don’t include the vector generalizations (or modifications for rotating reference frames) and won’t necessarily work for quantum systems.
Who says calculus isn’t useful
