Coeeficent Of Friction Lab

28 October 2008 Introduction: Static and energising encounter be issues that are a result of two surfaces in corroborate with each other. Static clangor is the forte that mustiness be overcome to cause an aim to gravel moving, while energizing friction occurs between two inclinations in motion sexual relation to each other. The kinetic friction run, Ff, kinetic, is specify by Ff, kinetic = μkFN, where μk is the coefficient of kinetic friction and FN is the popular personnel playing on the intent. The guckimum static frictional thread 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 endeavor. 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 point 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 tummy the coefficient of static and kinetic friction be determined for an object on a horizontal surface?
