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.
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.
-- 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.
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.
Air resistance will increase when the parachute opens, and the decent of the skydiver will slow down.
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.
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.
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.

During a skydiving jump, a parachute opens and deploys successfully through a process called deployment. When the skydiver pulls the ripcord, it releases the parachute from its container. As the parachute is released, it catches the air and inflates, slowing down the descent of the skydiver. This allows for a safe and controlled landing.
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.
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.
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.
