SUMMARY
The Freefall Velocity Formula, represented as V = √(2gΔy), is legitimate for calculating the speed of an object falling from rest without friction. In this formula, 'g' is the acceleration due to gravity, specifically 9.8 m/s², and Δy represents the vertical distance fallen. This formula effectively provides the final velocity after falling a specified distance, confirming its validity in physics.
