A parachutist's fall is due to gravity of the earth which pulls down the weight of the parachutist towards it. Initially there is no air resistance. The air resistance increases and acts against gravity. There is a phase the velocity is constant. When parachute opens, air resistance increases significantly and the parachutist accelerates upwards and velocity decreases until they balance. My question is that if the forces were balanced, the Air Resistance= Gravity and net force on the parachutist is 0 N, how come does the Parachutist move?
