Free Fall Motion and Velocity

The video tutorial explains the concept of free fall by rounding gravity to -10 m/s². It calculates the velocity and distance of a falling object over time, emphasizing the increase in distance fallen each second. The tutorial provides a conceptual understanding of acceleration due to gravity and its effects on velocity and distance.
