Cutubyo la soo saaray

In kasta oo halbeegyada cabbirka ay yihiin baaxadda loo dejiyay in lagu go'aamiyo baaxadda waxyaabaha aan la qiyaasi karin 'tirinta halbeegyada shaqsi', Unugyada la soo saaray waa kuwa laga soo qaatay cutubyada cabbiraadda, waxaana loo dalbadaa xoogaa xoogaa gaar ah.

Halbeeg cabbir dherer (mitirka), mid ka mid ah culeyska (kiiloogaraam), hal mar (labaad), mid koronto (ampere), mid heerkulka (kelvin), mid ka mid ah tirada maaddada ( mole), iyo mid ka mid ah xoogga iftiinka (candela). Toddobadaas waxaa suurtogal ah in la sameeyo isku -darka dhammaadka gaara mid kasta oo ka mid ah cutubyada la soo saaray, oo lagama maarmaan u ah cabbiridda fasal kale oo ifafaale ah. In kasta oo aysan ahayn unugyo aasaasi ah, haddana waxay weli yihiin xoog aad muhiim ugu ah aadanaha: Haddii aan la helin cutubyo la soo saaray, cabiridda xoogga, tamarta, cadaadiska, awoodda, xawaaraha ama dardargalintu suurtagal ma noqonayso.

Sida cabbirrada caadiga ah, cutubyada la soo saaray ayaa sidoo kale bixiya awooda lagu sameeyo beddelaad u dhexeeya noocyo kala duwan. Tusaale ahaan, waa wax caadi ah in halbeega cabirka 'Newton' loo isticmaalo in lagu cabbiro baaxadda xoogga, laakiin sidoo kale waxaa jira halbeegga cabbirka 'Dina', oo hoos imanaya xiriirka uu 1 newton u dhigmo 100,000 dynes. Wax la mid ah ayaa ku dhaca cabbirka tamarta, shaqada iyo kulaylka: Joules waxaa loo adeegsadaa dhinaca sayniska, laakiin kalooriyada waxaa loo isticmaalaa nolol maalmeedka. Xiriirku waa mid toosan, inta kaloorigu yahay 4.181 joules.

Liiska soo socdaa wuxuu ka kooban yahay shan iyo toban tusaalooyin oo ah cutubyo la soo saaray, oo tilmaamaya waxa ay u taagan yihiin inay matalaan, iyo isku -darka halbeegyada aasaasiga ah ee qiyaasta iyaga go'aamisa.
