Here's what it means:
* No other forces: The only force acting on the object is gravity. This means there's no air resistance, friction, or other external forces.
* Constant acceleration: Gravity causes a constant acceleration, which on Earth is approximately 9.8 m/s². This means the object's speed increases by 9.8 meters per second every second it falls.
Important Note: In reality, true free fall is difficult to achieve on Earth due to air resistance. However, the term is often used to describe situations where air resistance is negligible, such as objects falling from a great height.
