أخطاء شائعة يجب تجنبها
- ✕Confusing terminal velocity with escape velocity
- ✕Using incorrect drag coefficient for object shape
أسئلة شائعة
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.
