<prompt> Bheka isigaba esingezansi bese uphendula umbuzo emva kwalokho ngolimi olufanayo nesigaba: Isethulo: Umqondo wokulingana kokuziphendukela kwemvelo uhlobene eduze nenye ingxenye ye - physics evamile yokulinganisela. Emfundisweni ka-Einstein, kuvela ukuthi akunakwenzeka ukuthola incazelo ejwayelekile yemfanelo ebonakala ilula njengenani eliphelele lesimiso noma amandla. Isizathu esiyinhloko siwukuthi insimu yamandla adonsela phansi - njenganoma iyiphi insimu engokwenyama - kufanele inikezwe amandla athile, kodwa ukuthi empeleni akunakwenzeka ukuthola lawo mandla. Noma kunjalo, kunamathuba okuchaza isisindo esiphelele sesistimu, kungaba ngokusebenzisa umbukeli okude kakhulu i-ADM mass noma ukufanelana okufanele i-Komar mass. Uma umuntu engabandakanyi esimisweni sesisindo esiphelele amandla athuthwa aya endaweni engenamkhawulo ngamagagasi adonsela phansi, umphumela uba yisisindo sikaBondi endaweni engenamkhawulo. Njengoba nje kuyi - physics yakudala, kungaboniswa ukuthi lezi zinhlayiya ziyi - positive. Izincazelo ezihambisanayo zomhlaba wonke zikhona nge-momentum ne-angular momentum. Kuye kwaba nemizamo eminingana yokuchaza ubukhulu obucishe bube bendawo, njengobukhulu besistimu ehlukanisiwe eyenziwe kusetshenziswa kuphela ubukhulu obuchazwe esifundeni esiphelele sendawo equkethe leso simiso. Ithemba liwukuthi bazothola ubuningi obuwusizo ezitatimendeni ezijwayelekile mayelana nezinhlelo ezihlukanisiwe, njengokwakheka okunembe kakhudlwana kokuqagela kwe-hoop. Umbuzo: Iyiphi enye incazelo yobukhulu obucishe bube bendawo?  <response>: isisindo sohlelo oluhlukanisiwe olwenziwe kusetshenziswa kuphela ubuningi obuchazwe esifundeni esiphelele sesikhala esiqukethe lolo hlelo
