Practice question · True or false
In a free-fall experiment, air resistance can always be neglected regardless of the object's shape or speed.
Hints
- Air resistance depends on speed and on frontal area.
- A light sheet and a dense ball behave very differently.
Show the answer
False
Why
Air resistance depends on speed, shape, and cross-sectional area; it is only negligible for dense, compact objects at low speeds.
