What is the difference between the movement of a free body and the free fall of a body?

The movement of a free body is called such a movement in which other forces do not act on the body. No other body acts on it. The movement of a free body can only be uniform and rectilinear. Free fall of a body is called the movement of a body under the influence of only a single gravity. The body is acted upon by one force of gravity of the Earth, which is directed vertically downward. The motion of such a body is uniformly accelerated with gravitational acceleration g = 9.8 m / s2. When the body moves down, it accelerates, its speed increases. When the body moves up, then its speed decreases, the body slows down.
