16
Data: Simulation

17
Data: Mass vs. Apogee

18
Analysis: Mass vs. Apogee Results show Our rockets Can fly Kind of high Exemplifying a negative and nonlinear Trend

19
Data: Mass Vs. Acceleration Video

20
Data: Mass Vs. Acceleration

21
Data: Engine Type vs. Apogee

22
Conclusion Mass vs. apogee → exponential, negative Engine vs. apogee → logarithmic, positive Mass vs. acceleration → cubic polynomial To optimize model rocket flight, rocket mass must be minimized while still maintaining the center of gravity above the center of pressure. Additionally, upgrading the engine class makes the rocket go higher. These graphs present the optimal conditions for highest apogees.
