When a parachute opens and falls, air beneath it is compressed in the canopy. The compressed air holds the chute open, and the open chute presents a large cross sectional area to the air in the direction it is moving (which is down). The large cross section of the open chute means that as it moves through the air, the whole area of the open chute will present a "front" to the air, and it will make it difficult for the air to move out and up past the chute (or make it difficult for the chute to move down through the air, whichever you prefer). The net result is that the chute and its load (a person, a cargo pack, or whatever) won't be able to move nearly as quickly through the air as the load alone without the chute for drag.
If you wish to think through the problem and investigate further, you'll discover that the pressure in the chute is highest at the top in the middle. If a jumper opens his chute and a panel or two is blown out in some kind of failure, the jumper will have to make a decision about whether to cut away and open a reserve, open a reserve without cutting the primary chute away (and risking a tangle), or just riding the primary chute in with the blown panels. If the panels that have failed are in the sides of the chute, the incident is not as serious as if the panels that blew out are in the top. As the top is the higher pressure area of the chute, a blown panel is much more serious there as air at higher pressure is escaping through the chute (rather than out from under it and around it), and this will provide less "slowing" for the load on the chute. Again, think it through and consider what air is doing as the chute moves down through it and you'll be able to puzzle it out.

Does the material of a parachute affect how it falls?
Yes, the material of a parachute affects how it falls. The type of material used can impact the drag force, deployment speed, and overall stability of the parachute during descent. Different materials have varying strength, weight, and resistance to air flow, all of which can influence the way a parachute falls.
Does the area of a parachute affect how fast it falls?
Yes, the area of a parachute directly affects how fast it falls. A larger parachute will create more air resistance, slowing down its descent, while a smaller parachute will fall faster due to less air resistance.
What is the upwards force on a parachute called?
The upwards force on a parachute is called lift. It is created by the air resistance or drag generated by the canopy of the parachute as it falls through the air.
What is the force pushing a parachute up called?
The force pushing a parachute up is called drag. It is created when the parachute interacts with the air as it falls, slowing down its descent.
Is it true a parachute moves faster as it falls through air because the air rubs against it?
No, a parachute slows down as it falls through the air due to air resistance. The parachute creates drag which counteracts the force of gravity, causing it to descend at a controlled speed.

What page number is the scene where katniss falls off the parachute in Mockingjay?
The scene where Katniss falls off the parachute is on page 136 of the book "Mockingjay" by Suzanne Collins.
How will the mass under the parachute effect the way it falls?

Does increasing the size of the parachute change the speed at which it falls?
the bigger the parachute the slower it falls. but, that is dangerous because it carries more so they try not to make them to big because one gust of wind could blow you a mile to 2 miles off course.
What forces are acting on a parachute as it falls through the air?
On a parachute falling through the air, the main forces acting are gravity pulling it downward and air resistance pushing against it. Gravity accelerates the parachute towards the ground, while air resistance, or drag, slows down its descent. The balance between these forces determines the speed at which the parachute falls.
Why is parachute not uniformly accelerated?
A parachute is not uniformly accelerated because it experiences air resistance, which increases as the parachute opens and slows down the descent of the object. This non-uniform acceleration is caused by the changing forces acting on the parachute as it falls through the air.
How does the parachute helps an object to fall slowly?
A parachute works by increasing air resistance. When the parachute opens, it creates a large surface area that catches and slows down the air as the object falls. This increased air resistance reduces the speed at which the object falls, allowing it to descend more slowly and safely.
What are the parachutes for on a rocket?
The parachute of a rocket is used to slow down the rocket when it falls down.
