Estimate the terminal (steady) falling speed of an object when aerodynamic drag balances its weight.
输入质量 m、g、ρ、Cd、A,求终端速度。
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Terminal velocity | v_t = √(2W/(ρ·Cd·A)) | Quadratic drag model (Newton 1687) |
| Laminar special case | Stokes regime: v_t = gd²Δρ/(18μ) | Stokes, 1851 |
