Final answer:
Rocket experimentation methodology focuses on rocket propulsion based on Newton's third law and reaction stoichiometry of fuel mixtures to generate thrust, using the rocket equation for velocity changes.
Step-by-step explanation:
The methodology for experimenting with rockets involves understanding the principles of rocket propulsion, which is based on Newton's third law of motion. To increase a rocket's velocity, it will burn some amount of fuel, which results in a change of its mass. Also essential to rocketry is reaction stoichiometry, which ensures that chemical reactions from burning solid-fuel mixtures yield the necessary thrust. Such experiments may include using equations like the rocket equation, derived by Konstantin Tsiolkovsky, to find the change of velocity (Δu) regarding the mass of the fuel burned.
