An object in free fall will accelerate towards the Earth at approximately 9.8 m/s². This value is known as the acceleration due to gravity and is denoted by the symbol g.

Here are some important points to remember:

* Free Fall: This means the object is only under the influence of gravity. Air resistance is negligible.

* Constant Acceleration: The acceleration due to gravity is constant near the Earth's surface, meaning the object's speed increases by 9.8 meters per second every second it falls.

* Neglecting Air Resistance: In real-world scenarios, air resistance plays a role, slowing the object down. However, in ideal free fall situations, we ignore air resistance.
