<prompt> Bheka isigaba esingezansi bese uphendula umbuzo emva kwalokho ngolimi olufanayo nesigaba: Ukudlula: Kuyaziwa ukuthi amabhuku akhe amanothi athi uNewton wayebhekana ngasekupheleni kwawo-1660 nomqondo wokuthi amandla adonsela phansi omhlaba anwebeka, ngokulingana kwesikwele, kuya eNyangeni; kodwa-ke kwamthatha amashumi amabili eminyaka ukuthuthukisa inkolelo-mbono ephelele. Umbuzo wawungekhona ukuthi amandla adonsela phansi ayekhona yini, kodwa wawungukuthi ingabe ayekude kakhulu neZwe kangangokuthi ayengase futhi abe amandla abambelela iNyanga emzileni wayo. UNewton wabonisa ukuthi uma amandla encipha njengesikwele esiphambene sebanga, umuntu angakwazi ngempela ukubala isikhathi sokujikeleza kwenyanga, futhi athole ukuvumelana okuhle. Waqagela ukuthi amandla afanayo ayebangela ukunyakaza kweminye imijikelezo, ngakho wayiqamba ngokuthi amandla adonsela phansi endaweni yonke. Umbuzo: Uyini umqondo kaNewton wokudonsela phansi komhlaba?  <response>: uma amandla encipha njengesikwele esiphambene sebanga, umuntu angakwazi ngempela ukubala isikhathi sokujikeleza kwenyanga
