Hey, just started learning about forces and having trouble getting my head around forces acting on a parachutist and acceleration due to gravity. I understand that at terminal velocity Fg = Fair friction, my problem is when he opens his chute and starts to float down is he still accelerating to earth at g? His mass doesn't change so should g not change? Is he accelerating at g to a smaller velocity? just can't see how he has the same acceleration due to gravity when he is in free fall and with the chute open. Thanks.
