It is air resistance which slows the rate at which a parachutist falls, turning what would otherwise be a fatal fall into a controlled landing.

The air resistance will cause the parachutist to experience frictional forces that will reduce her kinetic energy compared to the scenario without air resistance. As she falls, some of her initial potential energy will be dissipated as heat due to the air resistance, resulting in a decrease in kinetic energy.
Gravity (downwards), and air resistance (upwards).
No, the air inside a ball does not affect how fast it falls. The rate at which an object falls is determined by gravity and the air resistance it encounters, not the properties of the air contained within the object.
When a parachutist is falling, the forces acting on them are gravity pulling them downward and air resistance pushing against their fall. Gravity is the dominant force causing the parachutist to accelerate towards the ground while air resistance counteracts this force, eventually leading to a terminal velocity where the forces are balanced.

The parachutist will go down, of course. If gravity is greater than air resistance, then the parachutist would accelerate (his speed would increase). This would increase air resistance, up to the point where gravity and air resistance are in balance.
Air resistance or upthrust :)
'Drag' which is air resistance.
You do, with a speed of 9.81m/s2 (Ignoring air resistance). When the parachute opens, the air resistance becomes very high, and so you decelerate to a certain speed (depending many different factors like air pressure and height.).

Air Resistance or friction with the air.
Air Resistance or friction with the air.
Air resistance acts up. Weight acts down. When they are equal in size, the parachutist falls at terminal velocity, without accelerating. Air resistance, like all frictional forces is electromagnetic.
