How does air exert an upward force on the parachute?

A parachute slows your descent after you jump out of a plane. In the parachute's frame of reference, wind is blowing upward toward it and its large area creates a great deal of upward drag force. This drag opposes your weight and slows your fall.

Answer 1

it actually occurs due to viscous force exerted by any fluids like air....since surface area of parachute is more more viscous force acts upon it

Answer 2

The shape of the parachute catches the air.



When a parachute is deployed it has a curve to it that catches the air providing more air resistance so it slows down the rate of fall. The parachutist has cords that control vents to let some of the air out and so steer the parachute.



Your explanation of the action of a parachute seems to be right so exactly what is your question?



The air is exerting an upward force on the parachute because it can’t get out of the way fast enough and it keeps getting more air thrust into it as it continues to fall.



According to Wikipedia: http://en.wikipedia.org/wiki/Parachute

“A parachute is made from thin, lightweight fabric, support tapes and suspension lines. The lines are usually gathered through cloth loops or metal connector links at the ends of several strong straps called risers. The risers in turn are attached to the harness containing the load. As the thin material inflates it increases drag and in turn slowing down the object it is carrying. The parachute successfully slows down the object enough so that it does not break on impact with the ground.”

I'm no "Rocket Scientist" but I believe the upward force you are reffering to is called "Gravity". If you have anymore silly ?'s feel free e-mail me
