Why and What I hope to achieve:
I believe that the purpose of doing this is to allow me to demonstrate my understanding of Elastic potential energy. And the projectile concepts of the effect of changing potential into kinetic energy and for me to demonstrate my ability to apply elastic potential energy to a scientific investigation.
What am I going to do and what will it prove:
I am going to use an elastic band and release it from different tensions I will then measure how far it ‘flies’.
Doing this will tell me the relationship between force, potential energy and kinetic energy.
My Prediction:
I predict that the further I pull the band back the further it will ‘fly’. This is based on the fact that the more tension involved means that the potential energy is greater therefore the kinetic/moving energy will also be greater.
Variables:
Force to pull the band back. This will be between 3 and 11 Newton’s.
Equations:
Distance = Speed
Time
Speed = Time
Distance
Time = Distance
Speed
I also have Equations for EPE in my research.
Method:
1) Attach an elastic band to the hook on the end of a Newton metre and stretch the band until the Newton metre reads three Newton’s
2) Then Release the band and see how far it flies.
3) Measure using a metre stick how far the band has travelled.
4) Repeat this same test three time in order to gather and average later on.
5) The repeat this test using forces of 5, 7, 9 and 11 Newton’s.
6) Remember to repeat each test on each force three times.
7) Then collect the mean average using the results you received from repeating each of the tests.
Fair Test:
I will make sure this is a fair test by:
· Using the same band each time
· Using the same height at which to release the band
· Repeat each test three times so that we gat a reasonable result and in the case of getting a ‘freak’ result I will repeat that test.
· Same place – Draught’s, heat
· Same angle when band is released
Things to take into account:
· The band will ‘age’ therefore losing some of its elasticity and tension.
· If it didn’t hit the ground it would probably go further.
· Use the same Newton metre and have the same person reading it.
· There might be a breeze of wind of some sort either flowing with the band or against it.
· Temperature of room
· Any possible obstructions or anything else that make effect the general momentum e.g. Doors opening windows being open or shut.
· Angle, position and height you release the band from.

I believe that Edgar Allan Poe did a wonderful job of portraying the effects of the horrible disease Red Death. Poe used a concept everyone knows of, a party, to display how sneaky and powerful the death was. Prince Prospero was the protagonist of “The Masque of the Red Death” and was according to the text, “he was happy, dauntless, and sagacious” (Poe 13). To escape the plague, Prince Prosper invited a thousand of “hale and lighthearted” (Poe 13) friends and courtsmen to come join him in his voluntary seclusion. They wanted to lock themselves inside the walls, to lock the Red Death out. As the party and plague continued to rule Prince Prospero and his friends, they all began to feel nervous and agitated for an unknown reason. The tension caused by these feelings was intensified when many individuals in the party became aware of a mysterious masked figure, who was sneakily and silently spreading its presence (sickness) around the castle. The shadowy masked figure was the Red Death itself. I loved this concept and plot because I believe that it appropriately infused this death with a happy and joyful time, which really showed The Red Death’s power and ever-presence during its reign.

"The prince had provided all the appliances of pleasure. There were buffoons, there were improvisatori, there were ballet-dancers, there were musicians, there was Beauty, there was wine. All these and security were within. Without was the 'Red Death,'" (209). As Edgar Allen Poe set the scene for his story, he also created an ominous mood and a sense of suspense supported by the setting. He details the fun and amusement inside the prince's abbey, in contrast to the horror and doom outside, and the reader's curiosity is piqued, because such bliss cannot be maintained for long. Throughout the story Poe explicates and changes elaborate environments to build the suspenseful energy and create a strong structure. In "The Masque of the Red Death," setting is employed to organize motives and action, and to focus the reader on the climax. Poe targets the culminating point of his story using rich descriptions of the abbey, the masquerade, and the clock.
The “Masque” can be a symbol for two things: hidden and elegance. The uninvited figure wore a bloody mask that concealed his or her identity and once the party guests attacked the figure, they found nothing behind the mask. Somehow, the figure was mysteriously hidden. The “Masque” can also be a symbol of elegance because the party were only for the wealthy and powerful. Also, prior to Prince Prospero charged towards the figure, the figure was walking gracefully and was in no rush through each room all the way to the seventh room. Furthermore, “Red Death” is a symbol for suffering and death. For example, “...profuse bleeding at its pores, with dissolution” (Poe 3). This shows that the victim suffers tremendously by constant bleeding with an addition of the body falling apart. Following that chaos, is a slow, horror-filled, and inescapable death as shown in the text, “And the whole seizure, progress, and termination of the disease, were the incidents of half an hour” (Poe 3). All in all, the title has a great impact on the
“The Masque of the Red Death” was written by Edgar Allen Poe in the 19th century. This story was written during the Gothic era. The stories that are written in the Gothic era is usually has to do with death, and lots of people were fascinated by the stories. There are many symbols in “The Masque of the Red Death”, yet I chose three, the first is all the colors of the room, second is the ebony clock and the last is the inside and outside of the abbey.
Edgar Allen Poe wrote the short story “The Masque of the Red Death” in 1842. While only one character is actually named, Prince Prospero, the story builds apprehension just based on the descriptions and not on dialogue. The narrator is never named and it is a mystery as to this person’s involvement in the story. The ambiguousness of the narrator also helps build the drama throughout the story. “The Masque of the Red Death” tells the story of a group of wealthy people who are trying to ignore and separate themselves from a terrible disease that is sweeping across their country. The disease is swift and brutal and can cause death within 30 minutes. The people infected weep blood from the pores on their faces and bodies, which causes a disturbing visual image. Poe uses the setting and symbolism to reiterate to the reader that death is inevitable.
Throughout the short story “The Masque of the Red Death,” Edgar Allan Poe uses vivid symbolism, structure, and reoccurring details to paint a powerful image regarding the finality and inescapable reaches of death itself. “The ‘Red Death’ has long devastated the country,” yet the Prince Prospero continues to hold extravagant parties for his fellow elite members of society. Rather than merely telling a series of events, Poe carries his readers throughout the many rooms and scenes that hold the Prince’s masquerade, up until the clock strikes midnight and the partygoers can no longer hide behind their façade, and death comes in to take those that thought themselves invincible (Poe 438-442).
The 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.

Gymnasts use physics everyday. As a gymnast I never realized how much physics went into every motion, every back handspring, every mistake on the bars. If gymnasts were physicists (or at least knew more about physics) they would be better equipped to handle the difficult aspects of gymnastics. As a gymnast I learned the motions that were necessary to complete the tricks that I was working on, and as a coach I taught others the same. I never truly understood why a particular angle gave me a better back handspring or why the angle that I hit a springboard at really mattered when completing a vault. We are going to explore some of the different apparatuses in gymnastics and a few of the physics laws that are involved in them. We will not even barely scratch the surface of the different ways that physics can explain gymnastics.
