How does the air resistance affect the parachutist's fall?
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.
A parachutist of mass 100 kg falls from a height of 500 m. Under realistic conditions she experiences air resistance. Based on what you know about friction what can you say about the kinetic energy of?
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.
What are the 2 forces acting on a parachutist?
Gravity (downwards), and air resistance (upwards).
Does the air in a ball affect how fast it falls?
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.
What are the directons in which the forces are acting when a parachutist when he is falling?
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.

Which direction does the parachutist go if gravity is greater than air resistance?
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.
The force which slows down a parachutist?
Air resistance or upthrust :)
What force slows down parachutist?
'Drag' which is air resistance.
Why does a parachutist not accelerate as he falls?
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.).

What is the force that slows a parachutist down as they fall through the air?
Air Resistance or friction with the air.
What is the force that slow a parachutist down a they fall through the air?
Air Resistance or friction with the air.
What kind of force opposes the motion of parachute?
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.

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.
