Ukuqonda Izinga Lokushisa Nokushisa

Izinga lokushisa . Umqondo wokushisa empeleni uvela ekuzweni kokushisa nokubanda okubonwa umuzwa wethu wokuthinta. Ngokusekelwe kulokho umuzwa wethu wokuthinta okuzwakalayo, sithi into ishisa kakhulu kunenye into noma into ibanda kakhulu kunenye into. Izinto ezishisayo zinezinga lokushisa eliphakeme kuyilapho izinto ezibandayo zinezinga lokushisa eliphansi. Uma into ibanda kakhulu, izinga lokushisa layo liphansi. Ngokuphambene nalokho, uma into ishisa kakhulu, izinga lokushisa layo liphakeme. Lesi silinganiso sokushisa noma ukubanda kwento sibizwa ngokuthi izinga lokushisa. Esihlokweni se-kinetic theory yamagesi esizofundwa kamuva ebangeni le-11, uzoqonda ngokujulile incazelo yokushisa; kwenzekani kuma-molecule akha into leyo into engayizwa ishisa, ifudumele, ipholile noma ibanda.

Incazelo yamayunithi aphesheya

Uhlelo Lwezinyunithi

Isibonelo, uma ulinganisa ubude bakho bese ububika njengo-100, umphumela awunamsebenzi. Ngokufanayo, uma ulinganisa isisindo somzimba wakho bese ububika njengo-20, umphumela nawo awunamsebenzi futhi awuqondakali kwabanye. Ngaphandle kokubika inombolo noma isibalo esithile, isilinganiso kumele sihambisane neyunithi. Uma uthi ukuphakama kwakho kungama-fathom ama-2, khona-ke u-2 yinombolo yokulinganisa kanti ama-fathom yiwo amayunithi owasebenzisayo. Abantu abajwayele ukusebenzisa ama-fathom bayaqonda lesi silinganiso. Noma, uma ulinganisa ubude betafula olisebenzisa ekilasini bese ububika njengobubanzi obu-5, umphumela uyaqondakala kwabanye abasebenzise ububanzi njengeyunithi.

Izinhlelo ezahlukene zamayunithi

Singaguqula amayunithi kusuka ohlelweni olulodwa lwamayunithi kuya kolunye, njengokusuka ohlelweni lwaseBrithani kuya ohlelweni lwamazwe ngamazwe , noma ngokuphambene nalokho. Isibonelo, uma silinganisa ubude betafula sisebenzisa irula ngamasentimitha (uhlelo lwaseBrithani) futhi sifuna ukuveza ubude ngamamitha (uhlelo lwamazwe ngamazwe), singaguqula isilinganiso kusuka kumasentimitha kuya kumamitha. Lokhu kuguqulwa kungenziwa kusetshenziswa isici sokuguqula.

Ubuningi obutholakalayo buyinani elibonakalayo elitholakala kunani elilodwa noma ngaphezulu eliyisisekelo . Ngaphezu kwamanani ayisisekelo ayisikhombisa, amanye amanani abonakalayo nawo ayinani elitholakalayo.

Ithebula lobuningi, amafomula namayunithiIndawo itholakala ngobuningi obubili bobude: ubude nobubanzi. Umthamo utholakala ngobuningi obuthathu bobude: ubude, ububanzi, nokuphakama. Isivinini sitholakala ngobuningi obubodwa bobude (ibanga) kanye nenani elilodwa lesikhathi. Ukusheshisa kutholakala ngobuningi obubodwa bobude (ibanga) kanye nenani elibodwa lesikhathi. Ubuningi butholakala ngobuningi obubodwa bobunzima kanye nenani elibodwa lobude. Amandla atholakala ngobuningi obubodwa bobunzima, inani elilodwa lobude, kanye nenani elibodwa lesikhathi.

Ubuningi obuyisisekelo buyinani elingokoqobo amayunithi alo anqunywe kusengaphambili futhi angatholakali kwamanye amanani. Ngo-1971, iNgqungquthela Jikelele Yezisindo Nezilinganiso yasungula ubuningi obuyisikhombisa obungokoqobo njengenani eliyisisekelo . Ubuningi obuyisikhombisa (7), kanye namayunithi nobukhulu bawo, buboniswe kuthebula elingezansi.

2 Izibonelo zemibuzo yokulingana komzimba eqinile

I-1. F₁ = 10 N, F₂ = 15 N kanye no-F₄ = 10 N, isebenza kubhulokhi i-ABCD njengoba kuboniswe esithombeni. Ubude bebhulokhi i-ABCD bungamamitha angu-20. Thola u-F₃ ukuze ibhlokhi libe se-static equilibrium. Unganaki ubunzima bebhlokhi.

Izilinganiso noma izibalo ku-physics zisukela kosayizi bezinhlayiya ezincane kakhulu, njengobunzima be-electron, kuya kobukhulu obukhulu kakhulu, njengobunzima bomhlaba. Ukubhala imiphumela yezilinganiso zezinto ezinkulu kakhulu, isibonelo ubunzima bomhlaba bungaba ngu-6,000,000,000,000,000,000,000,000 kg noma imiphumela yezilinganiso zezinhlayiya ezincane kakhulu, isibonelo ubunzima be-electron bungaba ngu-0,000,000,000,000,000,000,000,000,000,000,000,000,000.911 kg idinga isikhala esikhulu futhi ivame ukubhalwa ngokungalungile. Ukuze sinqobe le nkinga, singasebenzisa i-notation yesayensi.
