Ukuhlaziya ubukhulu obungokwenyama ingasetshenziswa ukuhlola ukunemba kokutholwa kwezibalo. Ekuqhubeni ukuhlaziywa kobukhulu, kungangezwa, kususwe, noma kulinganiswe kuphela amanani angokoqobo anezilinganiso ezifanayo. Uma amanani angokoqobo anezilinganiso ezifanayo noma ezahlukene ephindaphindwa, ahlukaniswe, noma akhushulwe abe amandla, ubukhulu balawo manani nawo aphindaphindwa, ahlukaniswe, noma akhushulwe abe amandla.
Inani eliyinhloko kanye nobukhulu
Ubuningi obutholiwe kanye nobukhulu
Isibonelo semibuzo yobukhulu befiziksi
| Ubuningi obuphathekayo | Amafomula obuningi obuphathekayo | Iyini inani eliyinhloko elihlanganisiwe? | Isilinganiso | Iyunithi |
| Indawo yendilinga | I-Pi x isikwele serediyasi (pir r2) | Ubude (2) | [L2] | m2 |
| Indawo yesikwele | I-Panjang x ububanzi | Ubude (2) | [L2] | m2 |
| Indawo yesikwele | Sisi x thina | Ubude (2) | [L2] | m2 |
| Indawo yebhola | 4 x pi x isikwele serediyasi (4 pir2) | Ubude (2) | [L2] | m2 |
| Amandla e-Kinetic | ½ x mass x isikwele sejubane ( ½ mv2) | Isisindo (1), ubude (2), isikhathi (2) | [M][L2]/[T2] | kg m2/s2 |
| Amandla adonsela phansi | Massa x ukusheshisa ngenxa yamandla adonsela phansi x i-ketinggian (mgh) | Isisindo (1), ubude (2), isikhathi (2) | [M][L2]/[T2] | kg m2/s2 |
| Ibhizinisi | I-Gaya x ukufuduka (F s) | Isisindo (1), ubude (2), isikhathi (2) | [M][L2]/[T2] | kg m2/s2 |
Ngokusekelwe ezibonelweni ezingenhla, kungaphethwa ngokuthi nakuba indawo yendilinga, indawo yesikwele, indawo yesikwele, kanye nendawo yesphere kunezindlela ezahlukene zokulinganisa, la manani anobukhulu obufanayo kanye namayunithi afanayo, ngakho-ke abhekwa njengohlobo olufanayo lobuningi obuphathekayo. Lokhu kusebenza nakumandla e-kinetic, amandla adonsela phansi, kanye nomsebenzi.
I-Catatan : Kunezinhlobo eziningana ezibonakalayo, nakuba zinezilinganiso namayunithi afanayo, ezingezona uhlobo olufanayo lobuningi. Isibonelo, i-torque nomsebenzi. Ifomula I-Torque = amandla (kg m/s)2) x ingalo yamandla (amamitha) ngakho-ke iyunithi yamazwe ngamazwe yi-Kg m2/s2Iyunithi ye-torque ifana neyunithi yomsebenzi noma yamandla, kodwa i-torque ayihlanganisi amandla.
I-Soal ubukhulu obungokwenyama.
