Subclaims¶

q2 i? Fitting the descending-sphere trajectory gave p2 = 1.404 s⁻¹, from which viscosity η ≈ 0.234 Pa·s was recovered via Stokes' drag law, within the literature range η ≈ 0.20–0.26 Pa·s. → Laura B. Alvarado-Cruz 2026

q2 · i? · design · r2

Parameter-interpretation analysis of Model 2 (linear drag) in the Results section. The exponential approach to terminal velocity was fitted (p1 = 0.2728 m/s, p2 = 1.404 s⁻¹, R² = 0.9967) and the recovered viscosity was judged "consistent with the viscosity of an aqueous glycerin solution".

"This is consistent with the viscosity of an aqueous glycerin solution (∼85% glycerin by weight) at room temperature (η≈0.20–0.26 Pa·s) [32, 33], indicating that the AI-generated scenario reproduces physically realistic behaviour"
