Explain why a man using a parachute falls through air slowly while a stone falls through air very fast?
When an object falls through air, it experiences air resistance. This air resistance is a force that opposes the object's motion. The amount of air resistance an object experiences depends on the object's shape, size, and speed. A man using a parachute falls slowly because the parachute creates a large amount of air resistance. A stone falls very fast because it has a small amount of air resistance.

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.
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 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 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 a parachute descends slowly where the stone dropped from the same height falls rapidly?
A parachute creates air resistance as it falls, slowing down its descent. The increased surface area of the parachute allows for more air resistance, counteracting the force of gravity. A stone, on the other hand, has a smaller surface area and experiences less air resistance, leading to a faster descent.

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 an open parachute increase air resistance of a falling skydiver?
the parachute has a big space area so that when he falls through the air the air molecules get collected by the parachute therefore reducing speed of falling down PS. doesnt mean he doesnt fall at all
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.
Ask us anythingA man steps out of a plane at a height of 4000 m above the ground falls 2000 m very quickly and then opens his parachute and slowly falls the remaining 2000 m to the ground. What height?
The man starts at a height of 4000 m and falls 2000 m quickly, which brings him down to 2000 m above the ground. After opening his parachute, he slowly descends the remaining 2000 m to the ground. Therefore, he ultimately lands at ground level, which is 0 m.
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 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.
Why parachute descends slowly whereas stone dropped from same height falls rapidly?
A parachute descends slowly due to its large surface area, which creates significant air resistance (drag) as it falls, allowing it to slow down and reach a stable descent speed. In contrast, a stone has a much smaller surface area relative to its weight, resulting in less air resistance. Therefore, the stone accelerates rapidly due to gravity until it reaches its terminal velocity, which is much higher than that of the parachute. This difference in drag effects explains the contrasting descent speeds.
