Strategic Workflow

The project follows the sequential stages:

  1. Establishing the ideal model — solve the projectile ODE system numerically under vacuum conditions and verify: it produces the expected parabolic trajectories.
  2. Build an atmospheric density model — fit a function \(\rho(h)\) to the NASA observational data.
  3. Combine — substitute \(\rho(h)\) into the drag force term of the ideal model and re-simulate.

Each stage builds directly on the previous one, which makes it straightforward to isolate the contribution of each addition. The details about the modeling process and application can be found on the next page.
