Investigation into elastic potential energy :: essays research papers fc

why and What I hope to achieveI believe that the purpose of doing this is to forego me to demonstrate my understanding of Elastic potential naught. And the projectile concepts of the effect of ever-changing potential into kinetic energy and for me to demonstrate my ability to apply chewy potential energy to a scientific investigation.What am I press release to do and what impart it proveI am going to utilise an lively stage set and release it from different tensions I will thusly measure how far it &8216flies&8217.Doing this will tell me the relationship between armament, potential energy and kinetic energy.My PredictionI predict that the hike I pull the draw back the further it will &8216 travel&8217. This is based on the fact that the more tension involved gist that the potential energy is greater therefore the kinetic/moving energy will also be greater.VariablesForce to pull the band back. This will be between 3 and 11 atomic number 7&8217s.EquationsDistance = look sharpTime promote = Time DistanceTime = Distance SpeedI also have Equations for EPE in my research.Method1)Attach an elastic band to the hook on the end of a Newton thousand and stretch the band until the Newton metre reads three Newton&8217s2)Then Release the band and see how far it flies.3)Measure utilize a metre stick how far the band has travelled.4)Repeat this resembling test three time in order to gather and intermediate later on.5)The double over this test using forces of 5, 7, 9 and 11 Newton&8217s.6)Remember to repeat each test on each force three times.7)Then collect the mean average using the results you accepted from repeating each of the tests.Fair TestI will falsify sure this is a fair test byUsing the analogous band each timeUsing the same height at which to release the bandRepeat each test three times so that we gat a reasonable result and in the font of getting a &8216freak&8217 result I will repeat that test.Same place &8211 Draught&8217s, heatSame angle when band is releasedThings to take into accountThe band will &8216age&8217 therefore losing close to of its elasticity and tension.If it didn&8217t hit the ground it would probably go further. example the same Newton metre and have the same person yarn it.There might be a breeze of wind of or so 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 start windows being open or shut.Angle, position and height you release the band from.
