Parachutes

Newton's first law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by an external force. In the case of a parachute, when deployed, it creates air resistance that opposes the force of gravity acting on the falling object. This air resistance slows down the object's descent, allowing it to reach a controlled and safe landing.

Air resistance, also known as drag, acts against a parachute's downward motion. As the parachute falls through the air, air molecules push against the surface of the parachute, creating a force that opposes its downward acceleration. This force helps slow down the parachute's descent, allowing for a safe landing.

The surface area, mass and the shape of the parachute affect the time of fall of the parachutes. Also the height, where the parachute have been dropped from. ( There are more factors that this).

Air resistance acts against the force of gravity, slowing down the descent of a parachute. The larger the surface area of the parachute, the more air resistance it creates, which helps to slow down its fall. Gravity, on the other hand, pulls the parachute downwards with a force proportional to the mass of the parachute. Balancing these forces allows the parachute to descend safely and slowly.

The hypothesis for parachutes could be: "If the surface area of a parachute is increased, then the rate of descent will decrease because the air resistance will be greater, resulting in a slower fall."

Parachutes increase air resistance by capturing a large amount of air in the parachute canopy. This creates drag, which slows down the fall of the object attached to the parachute, allowing for a safer descent. The drag force helps to counteract the force of gravity pulling the object downward.

Gravity and air resistance are the main forces acting on a parachute. Parachutes are pulled towards the ground by gravity, and if there was no parachute, the guy attached to the chute would turn into tomato paste. So parachutes are designed to create the maximum amount of drag (which is air resistance) so the whatever attached lands undamaged. So basically, parachutes create air resistance to reduce the effects of gravity

The manipulated variable in this experiment would be the size of the parachute. The scientist would change the size of the parachutes to see how it affects the time it takes for them to fall to the ground.

A small parachute would fall faster then a larger one because there is less air resistance trying to push the small one up but the larger one has a lot of air resistance because there is more area for the air to push up.

Hope this helped :P

As a parachute opens, it increases air resistance. This air resistance produces a force that counteracts the force of gravity pulling the object downward. Eventually, the forces reach equilibrium, causing the object to fall at a constant speed called the terminal velocity.

Increasing air speed will increase the rate of descent of round canopy parachutes due to a higher amount of air resistance acting against the parachute. This increased resistance creates more drag force on the parachute, causing it to fall faster.

If you have two parachutes, one big and one small, the biggest one will take more time then the other parachute. This happens because there is more room in the parachute which is causing air to go in side, which is air resistance. The smaller parachute has a lot of air resistance because it is smaller and there is less room for the air to go inside. However, the bigger balloon has little air resistance because it has more room in it for the air to get inside. The air is pushing the balloon up so it will fall slower.

Air resistance is the main reason that a parachutes slowly float to earth. the weightattached to the parachute keep it suspended in the correct shape to be effective. this is a very simplistic explanation and as can be seen from the many shapes and styles of modern parachutes there are other factors involved that can be used to modify the performance of a chute.

Thicker material can provide more strength and durability to parachutes, which can be beneficial for withstanding the forces of deployment and descent. However, thicker material can also add weight and decrease the flexibility of the parachute, potentially affecting its performance and agility. Finding the right balance between thickness, strength, and weight is crucial in designing an effective parachute.

-Nylon was the first man-made fabric to function as a synthetic substitute for silk. Now, as one of the strongest fabrics available, it is used in clothing, household goods, and other commercial and industrial products.

-Nylon was invented in the E. I. DuPont de Nemous & Company laboratory by the organic chemist, Wallace Carothers. He discovered the structure of natural polymers and used the information as the basis of his formula for synthetic polymers. He patented the fabric in 1935 and the first duPont nylon stockings became available for sale in the United States in 1939. Part of the original motivation for creating nylon was to produce a silk substitute, because of problems with importing Japanese silk into the United States at that time just prior to World War II.

Bigger parachutes have more surface area, which creates more air resistance. This air resistance slows down the descent of the parachute, causing it to take longer to reach the ground compared to a smaller parachute with less surface area.

A parachute works by trapping air underneath, but when the air is trapped the pressure increases and some of the air has to escape. If there were no hole in the center of a round parachute, such as the military 'chutes used in WW2, the excess air would have nowhere to escape except under the edges of the 'chute, which would cause increasingly violent oscillation and quickly the collapse of the 'chute, which would drop the parachutist to the ground at high speed and kill him. The central hole allows a controlled release of the air pressure in the 'chute, preventing oscillation and the collapse of the 'chute.

Air resistance, also known as drag force, is what slows down parachutes. As the parachute descends through the air, the air molecules create resistance, which counteracts the force of gravity pulling the parachute downwards. This drag force gradually reduces the speed of the parachute until it reaches a safe landing.

Parachutes use air resistance to slow down the fall of an object by creating drag. When the parachute is deployed, it fills with air and creates drag, which counteracts the force of gravity pulling the object down. This allows the object attached to the parachute to descend at a slower and safer speed.

The skydiver pulls out a pilot chute and releases it . The pilot chute then inflates and pulls the main canopy out of the pack, allowing it to open. This is how a sports skydiver opens his main parachute. Reserve parachutes are kept closed by a small pin holding a loop closed, and pulling a ripcord connected to this pin starts the deployment process. A spring loaded pilot chute is released, which inflates and pulls out the reserve parachute in a way similar to the main chute. This system is more reliable than the process used to pack the main parachute, but it is less convenient, and takes much longer to pack.
