The acceleration of a freely falling body is approximately 9.8 m/s², which is often rounded to 10 m/s² for simplicity.

This value is known as the acceleration due to gravity, and it's represented by the symbol g.

Important Points:

* Constant Acceleration: The acceleration due to gravity is constant near the Earth's surface, meaning that a freely falling body will increase its velocity by 9.8 meters per second every second.

* Neglecting Air Resistance: This value assumes no air resistance. In reality, air resistance will affect the actual acceleration of a falling object.

* Variation: The value of g actually varies slightly depending on altitude and latitude.
