* Air Resistance: As an object falls, it encounters air resistance. This resistance increases with speed, eventually reaching a point where it balances out the force of gravity. This is called terminal velocity. For a human, terminal velocity is roughly 120 mph (193 km/h).
* No "Forever" in Reality: The Earth has a finite atmosphere. Eventually, even if a person could fall unimpeded, they would exit the atmosphere and enter the vacuum of space. There would be no air resistance, but the force of gravity would also diminish significantly.
In a Theoretical Vacuum:
If we ignore air resistance and assume a theoretical vacuum, a falling object would continue accelerating due to gravity indefinitely. In this case, the velocity would theoretically approach infinity. However, this is a purely theoretical concept and not physically possible.
Key Takeaway:
The maximum velocity a human can reach while falling is limited by air resistance and the Earth's atmosphere. Even in a theoretical vacuum, the concept of "forever" falling is impossible.
