Here's what that means:
* Acceleration: It's the rate at which an object's velocity changes.
* Due to gravity: This means the change in velocity is caused by Earth's gravitational pull.
* 9.81 m/s²: This means that every second, the speed of a falling object increases by 9.81 meters per second.
Important Notes:
* This value is an average and can vary slightly depending on factors like altitude and latitude.
* It's often represented by the letter "g".
* The value is used in many physics calculations related to motion and gravity.
