Terminal velocity is the maximum speed reached by a falling object when air drag equals gravitational force. Different objects reach different terminal velocities.
단계별 가이드
- 1Enter mass, drag coefficient, reference area, and fluid density
- 2The calculator applies F_drag = F_gravity at equilibrium
- 3Results show terminal velocity
풀어진 예시
입력
m = 75 kg human, C_d = 1.15, A = 0.5 m² (head down)
결과
V_terminal ≈ 90 m/s (322 km/h)
Skydiver record
피해야 할 일반적인 실수
- ✕Confusing terminal velocity with escape velocity
- ✕Using incorrect drag coefficient for object shape
자주 묻는 질문
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.
