When her parachute opens, the air resistance increases. Now there is a resultant force going upwards on the parachute.
The increase in air resistance occurs because when the parachute is opened there is a much larger surface area (than before) so the particles of air are much more likely to get 'caught up' in the parachute unable to pass easily, therefore creating more air resistance (an upwards force) and so slowing down the parachutist.
NOTE: The parachutist does NOT move upwards after the parachute has opened, they just slow down. This effect comes from when a parachutist with a camera is filming opposite, they are still falling rapidly while the other person's parachute has opened, therefore passing them as they continue to freefall, and so the parachutist opposite appears to move upwards after opening the parachute.

∙ 12y agoThe main parachute system is designed to be released. This is done by pulling one handle, and through a system of a "three ring device" the skydiver falls away from the main parachute. He'll then deploy his reserve parachute. After landing the main parachute, and reserve pilot chute and freebag are located, all is packed up again and we're back on the airplane!

∙ 13y agoOnce a skydiver deploys his pilot chute, the drag created pulls the closing pin (attached to the bridle) and the deployment bag, containing the main canopy, is released. As the deployment bag is pulled upward, the lines are released from their rubber band stowes, which opens the deployment bag and exposes the main canopy. There is a rectangular slider made of the same parachute material as the canopy that slides down from the canopy to the risers that attach the canopy lines to the container (and thus to the skydiver). This ensures a slow, controlled canopy opening and a safe reduction in fall rate from terminal velocity to a much slower speed. The main canopy is fully deployed when the canopy is square (rectangular, actually) and the slider is all the way down and touching the risers. Now, after a controlability check, the skydiver is able to maneuver his canopy and make a safe, soft landing.

What happens to the air resistance as the parachute opens?
Air resistance will increase when the parachute opens, and the decent of the skydiver will slow down.
Compare the effects of gravity and air resistance on a falling skydiver before and after she opens her parachute.?
-- The force of gravity is unchanged before and after.-- The force of air resistance on the skydiver is greater before, and less after,because she is falling slower after the parachute opens.-- The effect on her of air resistance is greater after the parachute is open. Theincreased air resistance itself acts on the parachute, and its effect is transferredto the skydiver through her harness.

Why does a skydiver loose speed when he opens his parachute?
Because it fills with wind and increases his air resistance.
When a skydiver opens their parachute they move upwards?
When a skydiver opens the parachute, he or she does not move upward, but rather, continues to move downward, but at a slower speed. Sometimes there is an illusion that the skydiver is moving upward, because if there are several people skydiving together, and one of them opens a parachute while the others don't, you will see the skydiver with the open parachute moving upward with relation to the other skydivers. But they are all still moving downward, they are just doing so at different speeds.
Do sky divers go up when a parachute opens?
Sky divers do not go up, but they do undergo deceleration due to the increased drag incurred by the parachute being suddenly opened. Since skydivers, when being filmed by a cameraman, release their parachute first, there is a relative acceleration between the cameraman and the skydiver, creating the illusion that the skydiver is travelling up.
How far above the ground is the sky diver when he opens his parachute A skydiver jumps from an airplane 1000.0 m above the ground He waits for 8.0 s and the opens his parachute?
1/2 g t2. 1/2 x 9.81m/s2 x 64 9.81 x 32 313.92m. 1000-313.92=686.08
Why won't a skydiver's speed continue to increase until his or her parachute opens?
Once a skydiver jumps off the plane, they will begin picking up speed. However, as the speed of the skydiver increases, the amount of air resistance acting upon them will also increase. The skydiver will continue to accelerate while his or her weight is greater than the air resistance. When the force of the air resistance becomes equal to the weight of the skydiver, the skydiver will stop accelerating and will continue falling at a constant speed, this is known as the terminal velocity. While travelling at terminal velocity, the skydiver will be able to adjust his or her body position in a way that will increase or decrease the air resistance and allow the diver to alter their speed. Releasing his or her parachute will drastically increase the amount of air resistance and therefore slow their descent significantly.
What is a ripcord?
A ripcord is the part of a parachute pulled when the jumper is in the air to deploy the parachute canopy. (i.e., It opens the parachute when pulled)
Does a parachutist considered as a free falling object?
Yes, then not really, then definitely not: * Yes ... immediately after jumping. * Not really ... once terminal velocity is reached. * Definitely not ... after the parachute opens.
Why does a person loss speed if he opens parachute?
The parachute will increase air resistance, compared to the person alone.
How do parachutes work?
The skydiver pulls out a pilot chute and releases it . The pilot chute then inflates and pulls the main canopy out of the pack, allowing it to open. This is how a sports skydiver opens his main parachute. Reserve parachutes are kept closed by a small pin holding a loop closed, and pulling a ripcord connected to this pin starts the deployment process. A spring loaded pilot chute is released, which inflates and pulls out the reserve parachute in a way similar to the main chute. This system is more reliable than the process used to pack the main parachute, but it is less convenient, and takes much longer to pack.
