The reason I chose this experiment is because I like rockets and space travel. I like the part where you make the rocket and it is tedious work, but you get the fun to fly it over the heads of everyone. My topic could be used for a school project or something. Before I start to talk about how my rocket is going to be assembled, I’ll tell you a bit on the history of rockets. The first rocket were made in China using their gunpowder and the rockets were just used as fireworks. After a few years, the Chinese realised how deadly the rockets could be when they strapped rockets to arrows and fired them. After years of testing, the Chinese invented the first missiles. They included the multi-shot, (many rockets fired simultaneously) and the exploding rocket. Later, the Koreans decided to use the rockets to protect themselves against the invading Mongols. Anyway, back to the rocket project. The rocket body would be bought in a store, a usual one liter bottle. I would cut off the top of the rocket and use some more plastic to line the inside, around the rim of the top of the bottle. It is shown how it will be done in page one. I will use cardboard with cellophane wrap to not get the fins wet because i am using liquid for my rocket propultion. I will use Diet Coke and Mentos to propel my rocket. The mentos will react with the diet coke and will produce foam at such a fast pace that it will generate enough energy to lift the rocket off the ground. “Well, carbon dioxide is squeezed into the Diet Coke. That is why those sodas fizz.” (1) “The Mentos has a lot of nucleation sites, which is a perfect place for the carbon dioxide in the Diet Coke to produce bubbles. When there are too much bubbles they rise quickly to the surface of the Diet Coke... ... middle of paper ... ...he platform would be pretty wide and sort of heavy. It would have poles that fit snugly beside the rocket so that it would guide the rocket up not sideways. The launch pad would have an indentation so that it would catch the Mentos pieces as the were falling. When the rocket has no more energy to counter the gravity, it will fall. when that happens, the first nosecone will fall away, unfurling a parachute. If it works, it will have a less chance of landing and hurting someone. It would also not completely destroy the rocket in the process. That is how my rocket is going to work and some of it’s reactions.

...After Sonny brought home the win, all of Coalwood was happy for him and the BCMA. In celebration, the BCMA decided to make 6 more rockets and fire them off all day long after graduation. They advertised the launch all over town, and people came from all over to watch. The final rocket that they launched for the day was actually fired off by Homer Hickam Sr., Sonny’s father. Considering that his dad had never been supportive of his rockets, Sonny was honored and grateful to have his dad pull the string for the last rocket ever launched by the BCMA. Auk XXXI was 6 ½ feet long, and 2 ¼ inches in diameter. The rocket shot off into the air, becoming smaller and smaller as the crowd stood in awe watching the 6ft rocket become a tiny dot in the sky. Auk XXXI flew over 31,000ft, just under 6 miles, making it the most successful and memorable rocket the BCMA ever launched.
Thorough analysis of the graph displayed enough evidence suggesting that an increase in substrate concentration will increase the height of bubbles until it reaches the optimum amount of substrate concentration, resulting in a plateau in the graphs (figure 2). Hence; supported the hypothesis.
Cost management plays a major role when maintaining profit margins. Management must be able to find in which areas of a business costs must be reduced and the consequences that such reductions have in the overall company. In some situations management must change the way the work is being done in order to decrease costs while in other cases changing one supplier for another might be enough, in both situations a tradeoff will occur and the consequences will impact the company as a whole.
The earliest model was the trebuchet. It started by using a large weight on one end of a pivoting arm. The arm was pulled back the missile was placed and then let go. The weight went down, the arm went, and the missile launched. The later model gained its power from a tightly wound skein of rope, hair, and skin. the skeins were twisted incredibly tight and then had a wooden arm up to sixty feet long placed in between them. The arm was pulled back using pulleys and rope, the missile was placed in the wood cup and then the arm was released. The arm sprang to a 90 degree angle where it was stopped by a large padded piece of wood. The arm was then brought back down and fired again.
I will not be adding anything to my rocket, I was going to add glitter but that would hinder my rocket a great deal. Glitter creates friction and that friction would slow down my rocket and now allow it to travel the desired
Homer is amazed on how mankind, as a whole, launched an object into space and put it into orbit around Earth. Many people, in the 50’s and still to this day, can’t comprehend how accuracy is important when launching a rocket. According to NASA, rocket launches have to launch in a certain time period or they won’t go into orbit, potentially co...
Second, a science fair was held and only two were competing. One was George Melvil’s The Flying Machine: A System of Low-Resistance Pulleys, and Whit Austin’s Laser Cannon with Tracker. George’s project wasn’t even given a peep from the judges and that when he was trying to get their attention, Susan Singer-Wright, chair of the county commission, said to him that the fair already had a winner.

The Trebuchet was created by the Chinese in 300 BC and was known to be the most powerful of all the catapults. The Trebuchet was made of a long arm possibly up to 60 feet long, which balanced on a fulcrum, which was far from the center. A counterbalance, which is a heavy lead weight or a pivoting ballist box filled with earth, was attached to the short arm. A sling was attached to the end of the long arm and a rope was attached to the long arm, which was pulled down until the counterbalance reached its maximum height. The sling was loaded with projectiles as the rope was released and the counterbalance drops down. The potential energy is converted into kinetic energy and when the long arm is brought to an abrupt stop the projectile continue with the velocity produced by the kinetic energy
One thing that helped build a space rocket was a V-2 rocket built by the Germans during WWII. Throughout the years the V-2 rocket turned into the Saturn V rocket. The Saturn V was a rocket NASA built to send people to the moon. The Saturn V rocket was 363 feet tall and about the height of a 36-story-tall building. The Saturn V that launched the Skylab space station only had two stages. The Saturn V rockets used for the Apollo missions had three stages. Each stage would burn its engines until it was out of fuel and would then separate from the rocket and then the next one will start. If it wasn’t for the V-2 and German scientist, von Braun the USA would probably have not traveled to space. The USA sent astronaut John Glent to circle the Earth in 1962 to retaliate the launching of Sputnik. In 1969, a milestone was reached when the USA sent astronaut Neil Armstrong to the moon. The technology on the ship that took Neil to space was equivalent to a basic calculator built in 1980. They took a 64Kb computer (the moon lander) with them to space. It had approximately 64...
The paragraph above relates to model rockets because our rockets motor is made up of a special fuel. The fuels two reactants are Potassium Nitrate and sugar or sucrose. When these two reactants are mixed together and ignited they create a violent combustion. When my rocket is launched it will have it’s fuel ignited. The two reactants will combust and produce an exhaust that pushes the rocket forward.
The purpose of the projectile lab is to test the validity of the law of conservation of energy. The application of this law to our everyday lives is a surprisingly complicated process. Conservation of energy states that energy cannot be created or destroyed, but that it can be transferred from one form to another. Consider the projectile lab from document A that this essay is based upon. In an ideal experiment, the projectile is isolated from everything except the gravitational field. In this case, the only force acting on the particle is gravity and there are only two forms of energy that are of interest: the energy of the particle due to its motion (defined as kinetic
These engineers that were working for Phillip of Macedonia are trusted with building the first ballista. These model of catapult are used with two wooden arms, hard wound ropes and a cord to assist in the hurling of a deadly rocket, such as spears, at an enemy.
In order to launch fixed wing aircraft off aircraft carriers, the Navy uses catapults. The first recorded attempt at launching an aircraft off of a deck was in 1903 by Samuel Langley. Langley used a spring-operated catapult to launch his models and his, what would be failed attempt at a full scaled launch. In the following year, 1904, the Wright brothers had begun creating their own style of catapult to launch planes in a short distance. Their catapult was more of a derrick style, which was a pulley, cable, and weight. The weight would drop, which would in turn pull the cable attached to the launching gear of the plane. This system allowed for shorter launching areas, and more successful and longer flights (Track & Derrick). Almost a decade later, LT Ellyson became the first person to successfully launch from the Navy’s new catapult system. The system used compressed air, which could be monitored safely to ensure that the right amount of pressure was being applied to the launching system. No more than thre...
Is it ethical or even helpful to try to impose order on a haphazard existence? Is it right to play God, to steal the limelight from the cosmos? Man used to ponder existence, but with the increasing possibilities of science, we now ponder our power over existence. In “An Experiment with an Air Pump,” Shelagh Stephenson uses symbolism associated with Isobel as a voice of foreboding in a society “enraptured by the possibilities of science” (3). Stephenson associates Isobel with a bird, a pile of bones, and a sheep to reveal the dark side of the “light,” the scientific revolution.
