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.
A parachute increases the person's profile, so that more air hits (the parachute) whilst the person is falling. The collisions between the air and the parachute causes the person's descent to slow down.
The acceleration is due to gravity. She will reach a terminal velocity of about 120 MPH when the drag and the force of gravity are equal.
water cannot travel upwards, because 1) gravity 2) there is a property of water that does not allow it to flow upwards Water can move upwards by capillary action, forced upwards by a pump or natural geyser, it can be carried upwards and can rise in the form of steam or vapour.
If enough upthrust is added to an object then it will be pushed upwards. If enough air resistance is applied to an object then it will move in the direction which the air resistance is pushing it in. If you are already falling, then you will have air resistance. If it is increased when you open a parachute for instance, then you will slow down.

It's forced upwards by the pressure of the blood behind it. Additionally, there are valves in veins and arteries to stop the blood flowing backwards (kind of like a door that only opens one way).
In 2D, pressure moves in the direction of the force. If the force is an upwards force, it creates an upwards pressure. Your weight is a downwards force and it applies a pressure down onto the floor.
Skydivers do NOT move upwards at all when we open our parachutes. We don't even bounce a little. That is an illusion caused by the camera operator still falling at full speed while the first jumper opens their parachute and slows. Now, it is possible to move upwards in some limited circumstances. When exiting a fast-moving aircraft while wearing a wingsuit, you can rise above the plane for a (very) short time. Also, once your parachute is open, you can flare your canopy enough to slightly (by a few feet) gain altitude.
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 is not in freefall when they have opened their parachute. The move from free-fall to controlled decent under a wing.
when a skydiver jumps out of a plane, the dominant force is gravity, pulling him/her towards the ground, although some air resistance is also acting on him/her, allowing him/her to fall at a steady speed (not dropping like a stone), so the forces acting on the skydiver are almost balanced. of course, all that changes when the parachute opens. then the air resistance greatly increases, drastically slowing the descent down to earth.
to move arm upwards, the biceps contracts. Triceps don't do any work here~
only move upwards
Outwards and upwards
Downwards

Its called the Nutbush City Limits:)
The load will move upwards.
