Naked Egg Drop Lab Report Essays

Naked Egg Drop Lab Report Essays Naked Egg Drop Lab Report Paper Naked Egg Drop Lab Report Paper Things we learned that was relevant to the lab were what Potential Energy and Kinetic Energy was. Potential Energy is stored energy due to objects relative position, while Kinetic energy was energy of motion; amount of energy depends on objects mass and velocity. The lab with the roller coaster showed examples of when the coaster was at the highest point that it had more Gravitational Potential energy and that by the time it reached the bottom or the lowest point of the hill it had the most amount of Kinetic Energy. The goal of the lab was to make a contraption that if an egg was dropped from about 18 Ft it wouldnt break or even crack. We tried to absorb the force of the egg so that it wouldnt hot the ground with too much energy. The contraption had a net made of yarn to catch the egg and not have it bounce too much; it was slanted slightly so the egg could roll down into a soft pile of cotton that lined the bottom of the box. The purpose of the lab was to make a contraption that would prevent an egg from breaking if dropped from about 18 feet high. The egg was to land at the highest point of the net and roll gently down into the cotton lining at the bottom of the box. Materials: * Box 22 x 45 x 29 * Net (yarn) * Cotton Balls * Large Paperclips The data does make sense. If someones data was off the way it could affect our results was it could slight miscalculations or false information. Ways we deal with this data is we do at least 2 trials and average up the data to ensure that the data would be a bit more accurate. The way the results relate to the purpose statement is it helped determine the exact height of the drop, how much kinetic energy and gravitational potential energy the egg has at a given point, and how much force and impact the egg lands with. For example I could calculate the height of the drop, too make sure the calculations are accurate, using the d=vi t+1/2 tat; I calculated that the drop should be around 6. 71 meters or about 18 Ft, which is pretty close to the actually height . Errors that could have occurred were miscalculation, incorrect information, wrong time, wrong measurement, etc. We had several timers to make sure we had the timing as accurate as possible and we compared are data to make sure we got the same data. The goal of this lab was to make a contraption that would stop the egg from breaking when dropped from about 18 Ft and to find out how much potential and kinetic energy the egg has at a given time.

Manco Incas Rebellion (1536-1544)

Manco Incas Rebellion (1536-1544) Manco Inca’s Rebellion (1535-1544): Manco Inca (1516-1544) was one of the last native lords of the Inca Empire. Installed by the Spanish as a puppet leader, Manco grew increasingly angry at his masters, who treated him with disrespect and who were plundering his empire and enslaving his people. In 1536 he escaped from the Spanish and spent the next nine years on the run, organizing a guerrilla resistance against the hated Spanish until his assassination in 1544. Ascent of Manco Inca: In 1532, the Inca Empire was picking up the pieces after a long civil war between brothers Atahualpa and Huscar. Just as Atahualpa had defeated Huscar, a far greater threat approached: 160 Spanish conquistadors under Francisco Pizarro. Pizarro and his men captured Atahualpa at Cajamarca and held him for ransom. Atahualpa paid, but the Spanish killed him anyway in 1533. The Spaniards installed a puppet Emperor, Tupac Huallpa, upon Atahualpas death, but he died shortly thereafter of smallpox. The Spanish selected Manco, a brother of Atahualpa and Huscar, to be the next Inca: he was only about 19 years old. A supporter of the defeated Huscar, Manco was lucky to have survived the civil war and was thrilled to be offered the position of Emperor. Abuses of Manco: Manco soon found that serving as puppet emperor did not suit him. The Spaniards who controlled him were coarse, greedy men who did not respect Manco or any other native. Although nominally in charge of his people, he had little real power and mostly performed traditional ceremonial and religious duties. In private, the Spanish tortured him to make him reveal the location of more gold and silver (the invaders had already carted off a fortune in precious metals but wanted more). His worst tormentors were Juan and Gonzalo Pizarro: Gonzalo even forcibly stole Mancos noble Inca wife. Manco tried to escape in October of 1535, but was recaptured and jailed. Escape and Rebellion: In April of 1836 Manco tried to escape again. This time he had a clever plan: he told the Spanish that he had to go officiate at a religious ceremony in the Yucay Valley and that he would bring back a golden statue he knew of: the promise of gold worked like a charm, as he had known it would. Manco escaped and summoned his generals and called for his people to take up arms. In May, Manco led a massive army of 100,000 native warriors in a siege of Cuzco. The Spanish there only survived by capturing and occupying the nearby fortress of Sachsaywaman. The situation turned into a stalemate until a force of Spanish conquistadors under Diego de Almagro returned from an expedition to Chile and dispersed Mancos forces. Biding His Time: Manco and his officers retreated to the town of Vitcos in the remote Vilcabamba Valley. There, they fought off en expedition led by Rodrigo Orgoà ±ez. Meanwhile, a civil war had broken out in Peru between the supporters of Francisco Pizarro and those of Diego de Almagro. Manco waited patiently in Vitcos while his enemies made war on one another. The civil wars would eventually claim the lives of both Francisco Pizarro and Diego de Almagro; Manco must have been pleased to see his old foes brought down. Manco’s Second Rebellion: In 1537, Manco decided it was time to strike again. Last time, he had led a massive army in the field and had been defeated: he decided to try new tactics this time. He sent out word to local chieftains to attack and wipe out any isolated Spanish garrisons or expeditions. The strategy worked, to an extent: some Spanish individuals and small groups were killed and travel through Peru became very unsafe. The Spanish responded by sending another expedition after Manco and traveling in larger groups. The natives did not succeed, however, in securing an important military victory or driving the hated Spanish out. The Spanish were furious with Manco: Francisco Pizarro even ordered the execution of Cura Ocllo, Manco’s wife and a captive of the Spanish, in 1539. By 1541 Manco was once again in hiding in the Vilcabamba Valley. Death of Manco Inca: In 1541 the civil wars broke out again as supporters of Diego de Almagros son assassinated Francisco Pizarro in Lima. For a few months, Almagro the Younger ruled in Peru, but he was defeated and executed. Seven of Almagros Spanish supporters, knowing they would be executed for treason if captured, showed up in Vilcabamba asking for sanctuary. Manco granted them entrance: he put them to work training his soldiers in horsemanship and the use of Spanish armor and weapons. These treacherous men murdered Manco sometime in mid-1544. They were hoping to gain a pardon for their support of Almagro, but instead they were quickly tracked down and killed by some of Mancos soldiers. Legacy of Manco’s Rebellions: Mancos first rebellion of 1536 represented the last, best chance the native Andeans had of kicking out the hated Spanish. When Manco failed to capture Cuzco and annihilate the Spanish presence in the highlands, any hope of ever returning to native Inca rule collapsed. Had he captured Cuzco, he could have tried to keep the Spanish to the coastal regions and maybe force them to negotiate. His second rebellion was well thought-out and did enjoy some success, but the guerrilla campaign did not last long enough to do any lasting damage. When he was treacherously murdered, Manco was training his troops and officers in Spanish methods of warfare: this suggests the intriguing possibility that had he survived he many have eventually used the Spanish weapons against them. With his death, however, this training was abandoned and future rogue Inca leaders such as Tà ºpac Amaru did not have Mancos vision. Manco was a good leader of his people. He initially sold out to become ruler, but swiftly saw that he had made a grave mistake. Once he escaped and rebelled, he did not look back and dedicated himself to removing the hated Spanish from his homeland. Source: Hemming, John.
