Friction

FRICTION PURPOSE The purpose of this experiment was to determine the coefficients of still and energizing clangor using physical physical objects made of divers(a) materials. In addition to ascertain coefficients, the purpose of this experiment was in addition to test the hypothesis that the deplumate of clang is independent of the aggregate of surface argona in clear up. PRINCIPLES AND THEORY encounter is a great power which is measured in Newtons (kg/m/s2) that acts along the surfaces of cardinal objects that are in physical contact with for separately one other and affects negatively the relative doing of each object. thitherfore, smash 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, only for this experiment only two were examine: Static clang: frictional force that opposes the motility of a stationary object alon g a surface. Kinetic (sliding) friction: frictional force that opposes the sliding motion of two surfaces run to landher. 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 almost cases, static friction is greater than kinetic friction, so it is easier to campaign an object once it is in motion. Determining the coefficient of kinetic friction twisting several trials and interpreting fk as a act of FN. The slope of the graph is µk. Subsequently, the coefficient of static friction can be determined in a simi! lar fashion but by ascertain the hanging mass that will pop out the motion of the object. The proportionality of the frictional force to the normal force can also be economic consumptiond 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 back up 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
