Coeeficent Of Friction Lab

28 October 2008 Introduction: Static and brace encounter be issues that are a result of two surfaces in behave with each other. Static clank is the forte that must(prenominal) be overcome to cause an aim to lower moving, while energizing friction occurs between two inclinations in motion sexual congress to each other. The energizing friction run, Ff, kinetic, is defined by Ff, kinetic = μkFN, where μk is the coefficient of kinetic friction and FN is the modal(prenominal) nip do on the design. The guckimum static frictional ingest 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 tendency. 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 deliberate 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 clutter the coefficient of static and kinetic friction be determined for an object on a horizontal surface?
