You have a small person under the small parachute.
A parachute works as the gravity allows the parachute to go up into the air, then the surface area is covered with air resistance.
Depends what you mean by "better". A bigger parachute provides more wind resistant so if you were to jump out of a plane, you would want to go big. If your talking speed (like a running parachute) you would want a small parachute to accommodate how much harder you want to make your run
The best shape for a parachute is a circle. This is because the circle will have a larger area that will cause more drag to slow the parachute.
Paratrooper!!(:
cross sectional area for air resistance is greater as you increase the parachute size.
A small object has a larger surface area (in proportion to its weight) than a larger one. Therefore, a small object, like a small drop of water, will fall slower - it has more air resistance (again, in proportion to its weight). However, it will not float indefinitely; it will simply take longer to get to the ground.
The cloth surface area and the air rubs together causing friction or drag which slows the parachute down.
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
by increasing surface area
The surface area of a parachute can be different sizes and weights. If the surface is smooth then the you will fall faster because the texture is smooth and the air will slip by it. if it is rough then it will be slower because the the air will come into the parachute slower.
The decent rate will be significantly high on an open parachute because a 100 square foot parachute is considered to be very small. Therefore the wing loading is high and it is more likely to be a high performance parachute. High performance parachutes have a higher angle of attack and generally need to do a swoop (dive) landing to pick up enough wing speed for a safe landing. On touch down, the decent rate is the same as any other parachute for obvious reasons.
Parachutes are not rated by their speed. A parachute works by increasing the air resistance of a suspended falling body or object. The greater the mass of the object the larger the area of the parachute must be to reduce the speed to an acceptable level.
