Parachutes Investigation Aim The aim of this investigation is to find out how one chosen variable can affect the rate of descent of a parachute. There are many different factors that can be taken into consideration and varied to see what has the best effects on the rate of descent. The options where: a) The size of the canopy, b) The weight pulling on the parachute, c) The length of the chords, d) The shape of the canopy Also the forces acting on the parachute had to be taken
Parachute Experiment Prediction My prediction is that as the weight of plastercine increases the time taken for the parachute to reach the ground will decrease I think this because when the weight has just been dropped it is going slowly, but as it falls through the air it will gain speed until it reaches its terminal velocity. The weight does not change but the A.R gets bigger until it equals out the downwards force of gravity, so when the weight is larger it will have to fall further
Parachute Investigation Aim: The aim of this investigation is to see how the factors of terminal velocity affect it. Equipment: The equipment/ apparatus required for this investigation are: ü Large plastic bag-to make the actual parachute ü Two Styrofoam cups-represents “person”, holds the sand & measure sand ü Sand-acts as the weight of the “person” in cup ü 4 white string-attaches the parachute to one of the Styrofoam cups ü Small Ziploc bag-to contain sand and prevent from
Gravitational Pull and Parachute Investigation Aim The aim of the experiment is to investigate how each of several different weights of varying mass attached to a parachute in turn can influence the gravitational pull and air resistance forces acting on it, consequently affecting the time it takes to reach the ground when dropped from a specific height. Preliminary Work Forces are measured in Newtons (N), named after Isaac Newton who invented this unit. We cannot see them but instead
Research Question: How does the side lengths of a square parachute canopy affect the drop time of the parachute from a 460 cm drop height? The side lengths of the square parachute canopy will be 30 cm, 35 cm, 40 cm, 45 cm, 50 cm. The dependent variable would be the drop time of the parachute released from 460 cm(the drop time is determined by the time it takes for the parachute to touch the ground safely and softly from the release point). The dependent variable will be measured in seconds. Note:
The Forces at Work Gravity ... God OBVIOUSLY intended for us to skydive. After all He DID create gravity! So exactly what forces are acting on the skydiver? Well, of course there's the obvious one, the force of gravity of the Earth. This force is exerted on everything on the Earth and is exerted on the skydiver even though there is no direct contact between the skydiver and the Earth. This type of force, when two objects exert forces on one another even though they are not touching, is known
Terminal Velocity of a Paper Helicopter Introduction. Terminal velocity is the resulting occurance when acceleration and resistance forces are equal. As an example, a freefalling parachutist before the parachute opens reaches terminal velocity at about 120mph, but when the parachute is opened, terminal velocity is reached at 15mph, which is a safe speed to hit the ground at. This experiment will be no different, as I will be examining the terminal velocity of a freefalling paper helicopter
A lot of people debate, argue and even fight about whether or not one should take risks in life. As for me, I think there can’t be only one answer or solution to this question, for there are different types of risks and consequences that person might pay for. Health, money, job, opportunity and a lot more including even someone’s life, might all be associated with risks. My friend goes to Thunder Valley Casino and spends up to two thousand dollars every month. One’s success in life can depend on
When the fire goes out, the boys no longer want to be a part of civilization or be rescued by it.2. The beast from the air is a dead man, who is attached to a parachute, falling from the sky. The beast from water is a figment of their imagination. Once again the loss of civilization and the old ways are represented. The dead man in the parachute, falling slowly, from the old world and civilization, represents the steady decline of the old ways which have been implemented in the new society and therefore
for creating the parachute, but it was really in the 18th century when France both created it and used it by basically throwing themselves out of planes. Little did anyone know that skydiving would be one of the craziest sports today. Jumping out of a plane two and a half miles up into the sky would not be someone’s idea of a normal day. As bad as two and a half miles up in the sky is, try doing it traveling at a rate of one-hundred and sixty miles per hour with just a parachute to save you. To many
fluid dynamics underlie all objects in flight: The forces of Lift, opposing the downward acceleration of gravity, and the forces of drag due to air-resistance. Both forces, properly harnessed and controlled lead to such ingenious devices as the parachute and the helicopter. Aerodynamics, the field of fluid dynamics involving the flow of gasses, even has applications in fields as separate as the automotive industry, fire-safety, and golfing. The aerodynamics of paper airfoils, and additionally
was completely free of all worldly concerns; it was just me and the sky. Skydiving is an activity and sport in which people jump out of an aircraft, alone or in groups, and land by using a parachute. Because of the sensation of leaping into the air and free-falling some distance before opening their parachutes, skydivers usually experience a rush of adrenaline and then a peaceful sense of well-being. This feeling of calm lasts long after they land on the ground. Before feeling that calm however,
You would think after years of going to the same event you would get bored of it. I remember a few years that I was. But this year was different, something about me was different. The day of the Quad City Air Show was a cloudless day, full sun, incredibly humid, and terribly hot. It was possibly the worst weather to be out all day in. But, none the less, I was incredibly excited. It was the last Quad City Air Show, possibly ever, and my Dad, Papa, and Uncle Marvin decided to take myself and my best

Sivi, immediately came out
I have always been a thrill seeking person, and sky diving has been a thing I always wanted to do. When I finally got my chance, I couldn’t pass it up. My friends and I went to Florida during spring break. We were going to try something new for all of us. We were going to sky dive. It was a perfect April day for sky diving. The weather was nice and there wasn’t a cloud in sight, and no storms were going to be approaching anytime soon. We all drove down there together. Chris’s mom took us. We talked
he tells the others to follow him. He killed another pig and put the head of the pig on a stake, which symbolized The Lord Of The Flies. While Jack and the “hunters” were roasting the pig, Simon finds a dead man hanging from the rocks wearing a parachute. When he ran to tell the boys they mistaken him for the beast and kill him. Now only Ralph, Piggy and the twins remain together. The fight for leadership reaches a climax when Jack turns violent. The hunters stole Piggy’s glasses, broke the
the central emblem of the story lies in the dead airman. The boys mistake him for Beelzebub and basically begin to worship him. In fact, the most effective portrayal of Beelzebub appears early in the novel in the form of the dead airman. The parachute carries him through the night to the top of the mountain, where his body is entangled in the trees. It is in the way in which he is hung that makes it appear as if he was sitting on a throne of some sort. Sam n Eric first come upon it and are scared

Controlled Variables Variable Why it was controlled? How it was controlled? Mass attached for all parachutes It was controlled because the initial downward force had to be kept constant so air resistance will be the only factor. It was controlled by using the same 2 50g (0.05kg) bolt for each parachute, and all bolts were weighed on a mass balance Height of drop The height at which all the parachutes is dropped is kept constant because at higher heights the mass would have higher potential energy
eerie figure drifts down from the sky and lands in the forest several yards away from Sam and Eric. “There was a sudden bright explosion and corkscrew trail across the sky...There was a speck above the island, a figure dropping swiftly beneath a parachute, a figure that hung with dangling limbs. The changing winds of various altitudes took the figure where they would. Then three miles up, the wind steadied and bore it in a descending curve round the sky and swept it in a great slant across the reef
