Some students mistaken free fall with falling with a terminal velocity. But don't be fooled! A free falling object could never reach a terminal velocity. Terminal velocity is the falling condition in which air resistance balances the downward force of gravity. A free-falling object is an object upon which the only force is gravity. With no air resistance present, a free-falling object could never reach terminal velocity.
