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 allow me to border my understanding of Elastic possible energy. And the projectile concepts of the power 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 leave it proveI am going to use an elastic readiness and release it from contrary tensions I ordain then measure how farthermost it &8216flies&8217.Doing this will tell me the relationship between force, potential energy and kinetic energy.My soothsayingI predict that the further I pull the band bear the further it will &8216fly&8217. This is based on the fact that the much tension involved symbolises that the potential energy is greater thus the kinetic/moving energy will also be greater.Variables string to pull the band back. This will be between 3 and 11 Newton&8217s.Equations remoteness = SpeedTimeSpeed = Time Distan ceTime = Distance SpeedI also surrender Equations for EPE in my research.Method1)Attach an elastic band to the hook on the windup of a Newton measuring stick and stretch the band until the Newton metre reads three Newton&8217s2)Then Release the band and travel to how far it flies.3)Measure use a metre stick how far the band has travelled.4)Repeat this same block out three time in order to gather and average later on.5)The repeat this running play using forces of 5, 7, 9 and 11 Newton&8217s.6)Remember to repeat to each one test on each force three times.7)Then collect the mean average using the pass ons you received from repeating each of the tests.Fair visitationI will make sure this is a fair test by using the same band each timeUsing the same height at which to release the bandRepeat each test three times so that we gat a bonny result and in the case of getting a &8216freak&8217 result I will repeat that test.Same place &8211 Draught&8217s, agitateSame angle when band is releasedThings to take into accountThe band will &8216age&8217 therefore losing some of its elasticity and tension.If it didn&8217t hit the make 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 roomAny possible obstructions or anything else that make effect the general momentum e.g. Doors opening windows being open or shut.Angle, nonplus and height you release the band from.
