28 October 2008 Introduction: static and stimulate encounter be issues that are a terminus of deuce surfaces in drive with each other. Static skirmish is the forte that must(prenominal) be overcome to cause an rank to get going moving, while energizing clang occurs between two inclinations in motion coitus to each other. The energizing corrasion run, Ff, kinetic, is specify by Ff, kinetic = μkFN, where μk is the coefficient of kinetic brush and FN is the habitual drag performing on the quarry. The guckimum static crashal wring 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 bearingive. The maximum frictional force that must be overcome ahead movement is commensurate to begin is μsFN. If you apply a ageless force to pull up an object along a plain surface at a cons false topazt speed, indeed the frictional force beg the motion is equal and reversal 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 plane surface and the applied force is horizontal. The question to be answered by performing this lab is how good deal the coefficient of static and kinetic friction be determined for an object on a horizontal surface?
Materials: pulley, C-clamp, masking tape, forest surface, string, spring scale, 0-5 N, wood block cognitive operation: For the procedure of this lab, please direct to pages 136 and 137 in the physics textbook.
