Constants used on this page and their authoritative sources, for verification and citation
| Constant | Value | Unit | Source |
|---|---|---|---|
| Standard acceleration of gravity g_n | 9.80665 | m·s⁻² | ISO 80000-3 / BIPM conventional value (exact) |
Note: H = v²sin²θ/(2g) neglects air drag and Earth curvature; actual gravity varies with latitude and altitude (≈9.780 at the equator, ≈9.832 at the poles).
