Isayensi

Umthetho Wesithathu KaNewton ithi uma into 1 isebenzisa amandla entweni 2 khona-ke into 2 isebenzisa amandla entweni 1. Ubukhulu bamandla amabili buyafana kodwa isiqondiso samandla amabili siphambene. Amandla elilodwa libizwa ngokuthi isenzo, elinye amandla libizwa ngokuthi ukusabela.
Uphawu olungeluhle lubonisa isiqondiso samandla. Isenzo sika-F sihle, kanti ukusabela kuka-F kungabi kuhle. Lokhu kubonisa ukuthi amandla esenzo kanye nokusabela asezindleleni eziphambene.

Umthetho Wesibili KaNewton ithi uma amandla aphumelayo asebenza entweni engekho ziro, into izothola ukusheshisa. Ubukhulu bokusheshisa buhambisana nobukhulu bamandla aphelele futhi buhambisana ngokuphambene nobunzima bento. Isiqondiso sokusheshisa sifana nesiqondiso samandla aphelele.

Umthetho Wokuqala KaNewton ithi yonke into ephumule izohlala iphumule noma ... noma iphumule ... berukunyakaza okuqondile okufanayo izoqhubeka nokuhamba emgqeni oqondile ngesivinini esingaguquki uma amandla aphelele, noma amandla aphumelayo asebenza entweni, elingana no-zero. Isitatimende sezibalo somthetho wokuqala kaNewton:
Cabanga ngento ekuzungezile, njengetafula, idwala, noma yini enye. Itafula eliphumule lizohlala liphumule ngaphandle kokuthi lisuswe noma lifakwe amandla angaphandle, njengokusunduzwa noma ukudonswa. Kunjalo nangezinye izinto eziphumule.
