Would a parachutist be considered a free falling object and why?

The falling of a parachutist without his parachute deployed will be quite fast. We can slow his decsent by putting a drag on the free fall with a parachute. The fall is no longer free of drag (friction).

What happens the the kinetic energy of a falling object?
If the object's falling energy increases (this would happen if the object is already falling downward, and air resistance is small), then the kinetic energy will increase.
When object in elevator and elevator is falling downward then gravity is acting on it but why it is said that in this condition object is weightless?
Because when in the falling elevator, if you tried to weigh and object, it would not weigh anything.
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.
What is th true thing about a object in a free fall?
In the presence of a gravitational field, objects in free fall are uniformly accelerated. In a vacuum, all objects will fall at the same rate under the same gravitational attraction and would reach the ground at the same time. Falling through a fluid, resistance between the object and the fluid will cause the object to reach a maximum velocity as a parachutist does, being accelerated by the Earth's gravitation but being resisted by the air. All objects, having mass, have a gravitational field.
How does air resistance affect a falling helicopter?
the same that it would affect any falling object. The higher the air resistance the thicker the air density. This will result in a higher drag coefficient and will slow the fall of the object.
What happens the the kinetic energy of a falling object?
If the object's falling energy increases (this would happen if the object is already falling downward, and air resistance is small), then the kinetic energy will increase.
What would you call it when air resistance the force of gravity and a falling object stops accelerating?
When a falling object stops accelerating but is falling at a constant velocity, it is called terminal velocity.
When object in elevator and elevator is falling downward then gravity is acting on it but why it is said that in this condition object is weightless?
Because when in the falling elevator, if you tried to weigh and object, it would not weigh anything.
What would be the applied force of a free falling object?
gravity
Describe a place where a falling object would feel less drag than it would in your classroom?
A falling object would have less drag than in a classroom in a low pressure environment (higher up) or in a space or a vacuum, but then it's not really falling. Hope this clarifies.
What is the meaning of Free Falling?
Let's imagine there is no air resistance and that gravity is the only thing affecting a falling object. Such an object would then be in free fall. Freely falling objects are affected only by gravity
What is the shape of a displacement-time graph for an object that is constantly speeding up?
If the Object is falling at a constant velocity the shape of the graph would be linear. If the object is falling at a changing velocity (Accelerating) the shape of the graph would be exponential- "J' Shape.
How does air resistance affect the acceleration of falling objects?
As a falling object accelerates through air, its speed increases and air resistance increases. While gravity pulls the object down, we find that air resistance is trying to limit the object's speed. Air resistance reduces the acceleration of a falling object. It would accelerate faster if it was falling in a vacuum.
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.
How do you measure the weight at impact of a falling object?
