Iyunithi yomsebenzi
Impendulo ithi: Joule.
Iyunithi yokulinganisa yomsebenzi i-joule, okuyiyunithi evamile esetshenziselwa ukukala amandla nomsebenzi owenziwa ku-physics.
Umsebenzi ungachazwa njengamandla adingekayo ukuze uhambise into ethile ngamandla athile kanye nebanga elithile.
Umsebenzi ulinganiswa ngamajoule, okuyiyunithi yokulinganisa ohlelweni lwemethrikhi.
Le yunithi ejwayelekile yamukelwa emhlabeni wonke futhi iqashelwa emikhakheni eminingi yesayensi, efana nemishini, i-physics kanye nobunjiniyela.
Ama-joules angasetshenziswa ukukala amandla futhi adlulisele umlingiswa wokunyakaza othathwa ngumzimba, okudinga amandla athile kanye nebanga elithile.
Iyunithi ye-joule iyithuluzi lokulinganisa elibalulekile ku-physics nakwamanye amasayensi, lisiza ukuqonda ukuthi izinto zihamba kanjani futhi amandla aguqulwa esuka kwesinye isimo aye kwesinye.
