Newton's Third Law - Water Rocket Experiment by ETDtogo
Model
fy = -9.81+if (t<0.5,T,0)
thrust is constant at 23.4N
where T is 23.4 N.
what the model suggests is the thrust is 23.4 acting for 0.5 seconds at beginning of the video.
assumption
mass is constantthrust is constant at 23.4N
my observation
the flight path is roughly close the real motion.conclusion
of course, the model is flawed, but that is the nature of science, a better model gets made by building on other people's idea.challenge
can you build a better model?Reference:
