Free fall, in the context of physics, refers to the state of a body falling under the sole influence of gravity. When an object is in free fall, it is only subjected to the force of gravity, leading to a constant downward acceleration of 9.8 m/s^2. This means that in a vacuum, all objects fall with the same acceleration, regardless of their mass or shape

. The concept of free fall is fundamental in understanding the motion of objects under the influence of gravity and has implications in various fields, including mechanics, aeronautics, and general relativity
