Important Notes:
* This is an approximation. The actual acceleration due to gravity varies slightly depending on factors like altitude and the density of the Earth below.
* Air resistance affects falling objects. This means the actual acceleration experienced by an object will be less than 9.8 m/s² if it's affected by significant air resistance.
* Terminal velocity: As an object falls, it reaches a point where the force of air resistance equals the force of gravity. At this point, the object stops accelerating and falls at a constant speed, called terminal velocity.
