Reference
1 m ā 0.45 s Ā· 10 m ā 1.43 s Ā· 50 m ā 3.19 s (impact 113 km/h). Air resistance matters above roughly 30ā50 m for dense objects.
FAQ
Does mass affect fall time?
Not without air resistance ā all objects fall at the same rate (Galileo). With air drag, lighter objects with large area fall slower.
What is terminal velocity?
The speed where air drag equals gravity ā about 55 m/s (200 km/h) for a skydiver spread flat.
