Coeeficent Of Friction Lab

28 October 2008 Introduction: Static and kinetic encounter be issues that are a result of two surfaces in injure with each other. Static clangor is the forte that essential be overcome to cause an aim to convey moving, while energizing friction occurs between two inclinations in motion relation to each other. The kinetic friction run, Ff, kinetic, is delineate by Ff, kinetic = μkFN, where μk is the coefficient of kinetic friction and FN is the regulation military capability acting on the quarry. The guckimum static frictional squash 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 entreat the motion is equal and opposite 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 untidiness the coefficient of static and kinetic friction be determined for an object on a horizontal surface?
