Introduction: #hysic #hys ics s is a natu natura rall and and $uan $uanti tita tati tive ve sc scie ienc nce, e, relyi elying ng on accu accura rate te measurements of fundamental properties such as time, length, mass and tem tempera peratu turre. Thes These e prop proper erti ties es can can be meas measur ured ed by us usin ing g vari variou ous s instruments such as meter sticks, vernier calipers, micrometer calipers, triple%beam balances and laboratory thermometers. &n order to achieve the accuracy accuracy of the measur measured ed values values,, studen studentt needs needs to know know how to handle and use the instruments properly.  The instrument that is often used by us to measure measure length is meter ruler or stick. The smallest subdivision of the meter stick is millimeter, which means the millimeter is the unit of the smallest reading that can be made without estimating. The uncertainty of the meter stick is '.'(cm. ext is vernier caliper. This instrument is fre$uently used to measure the inner diameter and the outer diameter of an ob*ect. &n fact, the primary use of the instrument is to measure all those diameters. The uncertainty of the vernier caliper is '.''+cm. ther instrument that will be used for this measurement is micrometer. !efore using the micrometer, we need to identify the -ero error so that our value will be accurate and reliable. Micrometer can do the measurement down to '.( millimeter. o basically, the uncertainty of the micrometer is '.''(cm which is so small and precise. /astly, one of the instruments that measures mass is triple%beam balance. &t measures the mass of an ob*ect by balancing the unknown mass with sliding masses of known values. The unit used by triple%beam balance usually in gram. The uncertainty of the triple%beam balance is '.'(g.
