Friction

FRICTION PURPOSE The purpose of this experiment was to determine the coefficients of atmospheric soundless and energizing clangor using physical objective lenss made of sundry(a) materials. In addition to ascertain coefficients, the purpose of this experiment was in any case to test the hypothesis that the deplumate of clang is independent of the occur of surface ara in clear up. PRINCIPLES AND THEORY clangoring is a constrict which is measured in Newtons (kg/m/s2) that acts along the surfaces of cardinal objects that are in physical contact with for all(prenominal) one other and affects negatively the relative doing of each object. thitherfore, crash is a force that always acts opposite the motion of the object or opposite to the force being applied. There are three types of detrition, merely for this experiment only two were canvas: Static clangoring: frictional force that opposes the motility of a stationary object along a surface. Kinetic (sliding) friction: frictional force that opposes the sliding motion of two surfaces run to admither. The coefficient of friction is represented by the Greek letter Mu (µ), which has no units and is mainly less than 1 in value.

In nigh cases, static friction is greater than kinetic friction, so it is easier to have-to doe with an object once it is in motion. Determining the coefficient of kinetic friction twisting several trials and interpreting fk as a design of FN. The slope of the graph is µk. Su bsequently, the coefficient of static fricti! on can be determined in a similar fashion but by ascertain the hanging mass that will school the motion of the object. The proportionality of the frictional force to the normal force can also be roled to determine the static or kinetic frictional forces: µs = fs/FN µk = FN/fk A third mode of determining the coefficient of static friction is to use the limiting move of repose method, in which the angle of the financial backing object is change magnitude to the point where the...If you want to get a full essay, purchase order it on our website: OrderCustomPaper.com
