is a person falling with a parachute considered a free falling body?
falling through an atmosphere without a deployed parachute,or lifting device, is also often referred to as free fall. The aerodynamic drag forces in such situations prevent them from producing full weightlessness, and thus a skydiver's "free fall" after reaching terminal velocity produces the sensation of the body's weight being supported on a cushion of air.
Once the parachute opens, he is no longer freely fallingsince the air resistance will slow down the descent and help him land safely. So if the parachute is opened, it aint a free fall.
