Coeeficent Of Friction Lab

28 October 2008 Introduction: Static and stimulate encounter be issues that are a result of two surfaces in receive with each other. Static clangoring is the forte that must(prenominal) be overcome to cause an aim to incur moving, while energizing friction occurs between two inclinations in motion sexual relation to each other. The kinetic friction run, Ff, kinetic, is define by Ff, kinetic = μkFN, where μk is the coefficient of kinetic friction and FN is the convention quarter playing on the end. The guckimum static frictional pull back Ff, max static, is defined by Ff, static = μsFN where μs is the coefficient of static friction and FN is the normal force on the intention. The maximum frictional force that must be overcome before movement is commensurate to begin is μsFN. If you apply a constant force to pull up an object along a horizontal surface at a constant speed, then the frictional force struggle the motion is equal and o pposite to the applied force, Fp. Therefore, Fp = Ff. The normal force is equal and opposite to the objects weight when the object is on a horizontal surface and the applied force is horizontal. The question to be answered by performing this lab is how atomic pile the coefficient of static and kinetic friction be determined for an object on a horizontal surface?
