Ukuhlaziywa kobukhulu ku-physics kungasetshenziswa ukuhlola ukunemba kokutholwa kwe-equation. Ekuhlaziyweni kobukhulu, kuphela amanani angokoqobo anezilinganiso ezifanayo angangezwa, asuswe, noma alinganiswe. Uma amanani angokoqobo anezilinganiso ezifanayo noma ezahlukene ephindaphindwa, ahlukaniswe, noma akhushulwe abe amandla, ubukhulu balawo manani nabo buphindaphindwa, buhlukaniswe, noma bukhushulwe bube amandla.
Ubuningi obuyisisekelo 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.
Qaphela : Kunezinhlobo eziningana zomzimba, yize zinezilinganiso namayunithi afanayo, azifani. Isibonelo, i-torque nomsebenzi. Ifomula ye-torque = amandla (kg m/s 2 ) x ingalo yamandla (amamitha) ngakho iyunithi yamazwe ngamazwe yi-Kg m 2 /s 2. Iyunithi ye-torque ifana neyunithi yomsebenzi noma yamandla, kodwa i-torque ayifaki amandla.
