As learned in an earlier unit, free fall is a special type of motion in which the only force acting upon an object is gravity. Objects that are said to be undergoing free fall, are not encountering a significant force of air resistance; they are falling under the sole influence of gravity.

I’m pretty sure the only force pulling on a free falling body is gravity. Since gravity pulls things down to earth, the only way that the body can be falling “down to earth” is by gravity.
