Yimiphi imithetho emithathu yokunyakaza eyachazwa uNewton?
Context:Imithetho kaNewton yokuhamba iyimithetho emithathu eyisisekelo yemishini yama-classical echaza ubudlelwano phakathi kokuhamba kwento kanye namandla asebenza kuyo. Le mithetho ingachazwa ngale ndlela elandelayo:  Umzimba uhlala ungaphumuli, noma uhamba ngesivinini esingaguquguquki emgqeni oqondile, ngaphandle uma usetshenziswa amandla. Lapho umzimba uthintwa amandla, isilinganiso sesikhathi sokushintsha komfutho wawo silingana namandla. Uma imizimba emibili isebenzelana, la mandla anobukhulu obufanayo kodwa aqondana ngendlela ephambene. Imithetho emithathu yokunyakaza yaqala ukuvezwa u - Isaac Newton encwadini yakhe ethi Philosophiæ Naturalis Principia Mathematica (Izimiso Zezibalo Zefilosofi Yemvelo), eyanyatheliswa okokuqala ngo - 1687. UNewton wayisebenzisa ukuze aphenye futhi achaze ukunyakaza kwezinto eziningi ezingokwenyama nezinhlelo, okwabeka isisekelo semishini yama-classical. Kusukela ngesikhathi sikaNewton, okuqukethwe ngokomqondo kwe-classical physics kuye kwahlelwa kabusha ngezindlela ezihlukile, ezihilela izindlela ezahlukene zezibalo eziye zanikeza ukuqonda okwakungabonakali ekuhlelweni kwasekuqaleni, kukaNewtonian. Kuye kwatholakala nemingcele yemithetho kaNewton; izimfundiso ezintsha ziyadingeka lapho izinto zihamba ngejubane elikhulu kakhulu (i-special relativity), zinkulu kakhulu (i-general relativity), noma zincane kakhulu (i-quantum mechanics).
1. Izinkomo Umzimba uhlala ungaphumuli, noma uhamba ngesivinini esingaguquguquki emgqeni oqondile, ngaphandle uma usetshenziswa amandla. 2.
