Here's why:
* Freefall Definition: True freefall means the only force acting on an object is gravity. No other forces, like air resistance, are present.
* Air Resistance: As an object falls, it encounters air resistance. This force opposes the object's motion and increases as the object's speed increases.
* Initial Stage: Right after release, the object's speed is low, so air resistance is minimal. This means the object is primarily influenced by gravity, closely resembling freefall.
* Later Stages: As the object accelerates and gains speed, air resistance becomes more prominent. This force counteracts gravity, reducing the object's acceleration and causing it to deviate from true freefall.
In summary: While an object in freefall never truly experiences zero air resistance, it comes closest to freefall during the initial moments of its descent.
