Free fall literally means something is falling with no counter-directional force. For example, falling in a vacuum. If a person fell in the earth's atmosphere, he would be countered by drag (friction by air), which will lower his acceleration. If he fell in a vacuum, his acceleration will not be lowered due to the lack of a counter-directional force.
