Jak vypočítat Terminal Velocity
Co je Terminal Velocity?
Terminal velocity is the maximum speed reached by a falling object when air drag equals gravitational force. Different objects reach different terminal velocities.

Worked Examples
Vstup
m = 75 kg human, C_d = 1.15, A = 0.5 m² (head down)
Výsledek
V_terminal ≈ 90 m/s (322 km/h)

Common Mistakes to Avoid
- ✕Confusing terminal velocity with escape velocity
- ✕Using incorrect drag coefficient for object shape
Frequently Asked Questions
Does terminal velocity depend on height fallen?
No, once terminal velocity is reached, speed remains constant regardless of further fall distance.
Can terminal velocity be exceeded?
Not in normal circumstances; acceleration becomes zero at terminal velocity. Powered descent can be faster.
