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.

Why does a skydiver loose speed when he opens his parachute?
A skydiver loses speed when he opens the parachute because the parachute creates drag by slowing down the movement of air. This drag force opposes the motion of the skydiver, causing a decrease in speed. Additionally, the larger surface area of the parachute increases the effect of air resistance on the skydiver's body.
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.
When a skydiver opens their parachute they move upwards?
The skydiver doesn't move upwards when the parachute opens. In reality, the parachute creates air resistance, slowing down the skydiver's descent until they reach a safe landing speed. This process is what allows the skydiver to land safely.
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.
What effect terminal velocity and air resistance have on a sky diver when he opens his parachute?
When a skydiver opens their parachute, air resistance increases which slows down the skydiver. Terminal velocity is the maximum speed a falling object can reach when the force of gravity is balanced by the force of air resistance. Opening the parachute decreases the skydiver's speed, allowing them to land safely.
What force changes when a sky diver opens his parachute?
When a skydiver opens his parachute, air resistance (also known as drag force) increases. This is due to the parachute creating a larger surface area and creating more resistance against the air, which slows down the skydiver's fall. This increased air resistance counterbalances the force of gravity acting on the skydiver.
Why is a skydiver's speed wont continue to increase until his or her parachute opens?
A skydiver's speed doesn't continue to increase because of air resistance, also known as drag force. As the skydiver falls, the force of air resistance increases until it balances out with the force of gravity pulling them downwards. This causes the skydiver to reach a terminal velocity, the maximum speed they can achieve while falling, before the parachute opens.
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.
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.
What shape what is the displacement versus time for the skydiver be?
The shape of the displacement versus time graph for a skydiver would be a curve that starts at zero displacement when the skydiver jumps out of the plane, increases as the skydiver falls accelerating due to gravity, and eventually levels off as the skydiver reaches terminal velocity. The curve will then be a straight line at a constant displacement representing the terminal velocity until the skydiver opens the parachute, at which point the displacement will decrease as the skydiver slows down and lands.
What for what force changes want to sky drivers parachute opens What for stays the same?
The force changes to open a skydiver's parachute is primarily gravity as they descend. The force that stays the same is air resistance, which slows down the descent and helps regulate the descent speed.
