<prompt> Bheka isigaba esingezansi bese uphendula umbuzo emva kwalokho ngolimi olufanayo nesigaba: Ukudlula: Esisekelweni semishini yama-classical umqondo wokuthi ukunyakaza komzimba kungachazwa njengokuhlanganiswa kokunyakaza kwamahhala noma i-inertial, nokuphambuka kulokhu kuhamba kwamahhala. Ukuphambuka okunjalo kubangelwa amandla angaphandle asebenza emzimbeni ngokuvumelana nomthetho wesibili kaNewton, othi amandla asebenzayo emzimbeni alingana nobuningi balowo mzimba obungenamandla obuphindwe ngesivinini salowo mzimba. Izinhlelo ezithandwayo ze-inertia zihlobene nokwakheka kwendawo nesikhathi: ezinhlelweni ezijwayelekile zokubhekisela zemishini yama-classical, izinto ezihamba ngokukhululeka zihamba emigqeni eqondile ngejubane elingaguquki. Ngokukhuluma kwanamuhla, izindlela zabo ziyi-geodesics, imigqa yomhlaba eqondile esikhaleni sesikhathi esigobile. Ngakolunye uhlangothi, umuntu angalindela ukuthi ukunyakaza kwe-inertia, uma sekukhonjwe ngokubheka ukunyakaza kwangempela kwemizimba nokwenza izibonelelo zamandla angaphandle njenge-electromagnetism noma ukungqubuzana, kungasetshenziswa ukuchaza i-geometry yesikhala, kanye nesikhathi sokuxhumanisa. Nokho, kunokungaqondakali lapho amandla adonsela phansi esebenza. Ngokusho komthetho kaNewton wokudonsela phansi, futhi ngokuzimela kuqinisekiswe ngokuhlolwa okufana nokuka-Eötvös nabalandeli bakhe bheka ukuhlolwa kuka-Eötvös, kukhona ubukhona bokuwa kwamahhala okwaziwa nangokuthi isimiso sokulingana esibuthakathaka, noma ukulingana kwendawo yonke kwe-inertial ne-passive-gravitational mass: umzila womzimba wokuhlola ekuweni kwamahhala uncike kuphela esimweni sawo nesivinini sokuqala, kepha hhayi kunoma yiziphi izakhiwo zawo ezibonakalayo. Inguqulo elula yalokhu ifakwe ekuhlolweni kwe-elevator ka-Einstein, okuboniswe emfanekisweni ongakwesokudla: kumbonisi osegumbini elincane elivaliwe, akunakwenzeka ukunquma, ngokwenza imephu yomzila wemizimba efana nebhola eliwile, ukuthi ngabe igumbi liphumule emkhakheni wamandla adonsela phansi, noma esikhaleni samahhala esikhaleni se-rocket esisheshisa ngesilinganiso esilingana nesomkhakha wamandla adonsela phansi. Njengoba kunikezwe ubukhulu bokwehla kwamahhala, akukho mehluko obonakalayo phakathi kokunyakaza okungenamsebenzi nokunyakaza ngaphansi kwethonya lamandla adonsela phansi. Lokhu kusikisela ukuthi... Umbuzo: yini eyenza i-objest iwele ngokukhululekile?  <response>: amandla adonsayo
