Model Validation

Mathematical Model Validation

10 cases · Newtonian projectile equation · ±0.5% tolerance · run 2026-05-13

y(x) = x · tan(θ) − g·x² / (2·V0²·cos²(θ))

Classical mechanics (Galileo, Newton — public domain XVII century). Each test case runs 100 sample points through the simulator and computes max deviation from the analytical equation.
