Amasu Ayisisekelo Okulinganisa I-Physics: Isisekelo Esiyinhloko Ekuhlolweni
I-Pengantar
Ukulinganisa kuyisici esiyisisekelo sefiziksi, okusivumela ukuthola idatha yokulinganisa mayelana nomhlaba osizungezile. Amasu okulinganisa efiziksi ayisisekelo ahlanganisa amathuluzi nezindlela ezahlukahlukene ezisetshenziswa ukukala ubuningi obubonakalayo, njengobude, isisindo, isikhathi, izinga lokushisa, njalo njalo. Lesi sihloko sizoxoxa ngamanye amasu okulinganisa ayisisekelo asetshenziswa njalo ekuhlolweni kwefiziksi, kanye nezimiso ezihambisana nawo.
1. Ukulinganisa Ubude
Ukulinganisa ubude noma ibanga kungenye yemisebenzi eyisisekelo kakhulu ku-physics. Izinsimbi zokulinganisa ezivamile zifaka phakathi ama-ruler, ama-vernier caliper, kanye nama-micrometer screw gauges.
Inkanyezi
Irula liyithuluzi lokulinganisa elilula nelilula kakhulu lokulinganisa ubude. Ngokuvamile lenziwe ngokhuni, ipulasitiki, noma insimbi, irula linesilinganiso esimakwe ngamamitha, amasentimitha, namamilimitha. Ukungaqiniseki kokulinganisa ngerula ngokuvamile kucishe kube ngu-±0.5 mm.
Ama-caliper e-Vernier
I-caliper iyithuluzi lokulinganisa elinembile kakhulu kunerula. Ingalinganisa ubude ngokunemba okufika ku-0.1 mm. Leli thuluzi liqukethe imihlathi emibili, eyodwa eqinile neyodwa ehambayo, kanye nesikali se-vernier sokufundwa okuningiliziwe.
Isikulufa se-Micrometer
Igeyiji yesikulufu se-micrometer iyithuluzi lokulinganisa elinezinga eliphezulu kakhulu lokunemba, ngokuvamile elicishe libe ngu-±0.01 mm. Lisetshenziselwa ukukala izinto ezincane noma ezincane. Igeyiji yesikulufu se-micrometer iqukethe umshafu oqinile kanye nomshafu ohambayo, ngamunye uhlonyiswe ngesikali esijikelezayo ukuze kulinganiswe ngokunembile.
2. Ukulinganisa Isisindo
Isisindo yinani elibonisa inani lezinto entweni. Ku-physics, isisindo silinganiswa kusetshenziswa ibhalansi noma isikali.
Izikali ze-Analog
Isikali se-analog siyisikhali sokulinganisa isisindo esisebenzisa isipilingi ukukala isisindo sento. Amandla adonsela phansi asebenza esisindweni sento abangela ukuthi isipilingi seluleke, futhi isikali sibonisa isisindo sento. Ukungaqiniseki kokulinganisa ngesikali se-analog kungahluka kuye ngesimo sesipilingi kanye nokulinganiswa kwento.
Izikali zedijithali
Izikali zedijithali zinikeza izilinganiso zesisindo ngezinga eliphakeme lokunemba kunezikali ze-analog. Lawa madivayisi asebenzisa izinzwa ze-elekthronikhi ukukala isisindo nokubonisa imiphumela ngedijithali. Ukunemba kwezikali zedijithali kungafinyelela amagremu noma ngisho nama-milligram, kuye ngohlobo kanye nekhwalithi yedivayisi.
3. Ukulinganisa Isikhathi
Isikhathi singenye yezibalo eziyisisekelo ku-physics, ezivame ukulinganiswa ngewashi elimiswayo, iwashi, noma idivayisi yokulinganisa isikhathi kagesi.
Isitophuwashi
Iwashi lokumisa liyithuluzi lokulinganisa isikhathi elivame ukusetshenziswa ezivivinyweni zefiziksi. Amawashi okumisa angaba yi-analog noma idijithali, kanti awedijithali ngokuvamile anokunemba okungafika kumasekhondi angu-0.01. Avame ukusetshenziswa ezivivinyweni ezidinga ukulinganisa izikhawu zesikhathi ezimfushane.
Iwashi Le-Atomic
Ukuze kulinganiswe isikhathi ngendlela enembile kakhulu, kusetshenziswa amawashi e-athomu. Amawashi e-athomu asebenzisa ukuzwakala kwama-athomu (ngokuvamile i-cesium noma i-rubidium) ukuze agcine isikhathi. Amawashi e-athomu angaba nembe ngaphakathi komzuzwana owodwa eminyakeni eyizigidi, okwenza kube nokulinganisa isikhathi okunembe kakhulu ocwaningweni lwesayensi.
4. Ukulinganisa Izinga Lokushisa
Izinga lokushisa liyinani elibonisa amandla ajwayelekile e-kinetic ezinhlayiya entweni ethile. Lilinganiswa kusetshenziswa i-thermometer noma enye idivayisi efanele izinga lokushisa kanye nohlobo olulinganiswayo.
I-Thermometer ye-Mercury kanye ne-Alcohol
Ama-thermometer endabuko asebenzisa i-mercury noma i-alcohol njengoketshezi olubonisa inkomba. Njengoba izinga lokushisa likhuphuka, lolu ketshezi luyanda futhi lukhuphuke epayipini le-capillary, lufinyelele esikalini esithile esibonisa izinga lokushisa. Ukunemba kwala ma-thermometer ngokuvamile kuncike ebangeni lawo lokulinganisa kodwa ngokuvamile kungamadijithi edesimali.
I-Thermometer Yedijithali
Ama-thermometer edijithali asebenzisa izinzwa ze-elekthronikhi ukukala izinga lokushisa nokubonisa imiphumela ngedijithali. Izinzwa ezivamile yi-thermocouples noma ama-RTD (Resistance Temperature Detectors). Ama-thermometer edijithali avame ukufundeka kalula futhi anganikeza izilinganiso ezinembile, ngokunemba kuze kufike ephuzwini ledesimali eliseduze.
5. Ukulinganisa Amandla kagesi kanye neVolthi
Ukulinganisa ugesi wamanje kanye ne-voltage kuyisici esibalulekile sokutadisha ugesi kanye ne-elekthronikhi. Izinsimbi ezisetshenziswayo zifaka phakathi ama-ammeter, ama-voltmeter, kanye nama-multimeter.
i-ammeter
I-ammeter iyithuluzi elisetshenziselwa ukukala ugesi kusekethe. Ixhunywe ngokulandelana nesekethe ukukala ugesi ogeleza. Ukunemba kwe-ammeter kuncike ohlotsheni kanye nekhwalithi yedivayisi, kodwa ngokuvamile isetshenziselwa ukukala ugesi ngokunemba kwama-milliamperes.
I-Voltmeter
I-voltmeter ilinganisa i-voltage phakathi kwamaphuzu amabili kusekethe. Ixhunywe ngokuhambisana nengxenye okuzolinganiswa i-voltage yayo yokugcina. Ama-voltmeter edijithali anamuhla anganikeza ukufundwa okunembile ezindaweni eziningana zedesimali.
I-Multimeter
I-multimeter iyithuluzi lokulinganisa elisebenziseka kalula elingalinganisa ugesi, i-voltage, kanye nokumelana. Ama-multimeter atholakala kokubili ezinguqulweni ze-analog nezedijithali, kanti awedijithali ngokuvamile anikeza ukunemba okukhulu futhi kulula ukuwafunda.
6. Izimiso Eziyisisekelo Zokulinganisa
Ekulinganisweni ngokomzimba, kunezimiso eziningana eziyisisekelo okumele zilandelwe:
Ukulinganisa
Ukulinganisa kuyinqubo yokuqhathanisa ithuluzi lokulinganisa nezinga elaziwayo ukuqinisekisa ukunemba kwalo. Izinsimbi zokulinganisa ezingalinganiswanga zingakhiqiza idatha echemile noma enephutha, ezothinta imiphumela yokuhlola.
Ukungaqiniseki Kokulinganisa
Yonke indlela yokulinganisa inokungabaza okumele kuqashelwe. Lokhu kungaqiniseki kungabangelwa ithuluzi lokulinganisa, indlela yokulinganisa, noma ezinye izici zangaphandle. Ukusho ukuthi ukungaqiniseki kokulinganisa kuyingxenye ebalulekile yokubika kwesayensi.
Izilinganiso Eziphindaphindwayo
Ukuthatha izilinganiso eziphindaphindwayo kusiza ekunciphiseni amaphutha angahleliwe futhi kunikeze idatha ethembekile kakhudlwana. Isilinganiso sezilinganiso eziningana sivame ukusetshenziswa ukuthola inani elimelela kakhudlwana.
Amaphutha Ahlelekile Nangahleliwe
Amaphutha ahlelekile amaphutha ahlala ephambuka ohlangothini oluthile, abangelwa izici eziqinile, njengezinsimbi zokulinganisa ezingalinganiswanga. Amaphutha angahleliwe amaphutha ahlukahluka ngokungahleliwe, abangelwa izici ezingalindelekile noma ezingalawuleki.
Isiphetho
Ukulinganisa kuyisisekelo sazo zonke izivivinyo ku-physics. Ukuqonda amasu ayisisekelo okulinganisa ngokomzimba nokuqonda izimiso eziyisisekelo kuyisinyathelo sokuqala socwaningo lwesayensi olunembile noluthembekile. Ngezinsimbi zokulinganisa ezifanele, izindlela ezifanele, kanye nokuqonda okuphelele kokungaqiniseki kokulinganisa, ososayensi bangathola idatha efanelekile futhi bafinyelele iziphetho ezithembekile ezivivinyweni zabo.
