The acceleration due to gravity for an object falling to Earth, ignoring air resistance, is approximately 9.81 meters per second squared (m/s²). This value is often rounded to 10 m/s² for simplicity in calculations.

Here's why:

* Gravity is a constant force: The Earth's gravitational pull acts on all objects near its surface with a constant force.

* Acceleration is the change in velocity: This constant force causes objects to accelerate downwards, meaning their velocity increases at a constant rate.

* Standard value: The acceleration due to gravity (g) is a standard value that is used in physics calculations.

Important Note:

* The value of 9.81 m/s² is an average. It can vary slightly depending on factors like altitude and latitude.

* Air resistance is a significant factor in real-world scenarios. It opposes the downward motion of falling objects, leading to a slower terminal velocity.
