<prompt> Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu: Passage: Panheyo ye mechanics yekare pane pfungwa yokuti kufamba kwemuviri kunogona kurondedzerwa sekubatanidzwa kwekufamba kwakasununguka kana kuti inertial, uye kutsauka kubva mukufamba kwakasununguka uku. Kutsauka kwakadaro kunokonzerwa nemasimba okunze anoshanda pane chimwe chinhu maererano nomutemo wechipiri waNewton, uyo unotaura kuti simba rinoshanda pane chimwe chinhu rakaenzana nehuremu hwokusaita basa hwechinhu ichocho hwakapetwa nokumhanyisa kwacho. Kufamba kweinertial kunodiwa kwakabatana nejometri yenzvimbo nenguva: mumatanho akajairika enongedzo yemakemikari echinyakare, zvinhu zviri kufamba zvakasununguka zvinofamba mumitsetse yakatwasuka nekumhanya kusingaperi. Mukutaura kwemazuva ano, nzira dzazvo ndidzo geodesics, mitsetse yenyika yakarurama munzvimbo yakakomberedzwa. Zvakare, mumwe angafungidzira kuti kufamba kweinertial, kana kwazivikanwa nekucherechedza kufamba chaiko kwemiviri uye kugadzira mvumo yemasimba ekunze akadai semagetsi emagetsi kana kukakavara, inogona kushandiswa kutsanangura geometry yenzvimbo, pamwe nekuronga nguva. Zvisinei, pane kusanzwisisika apo simba rinokwevera zvinhu pasi rinotanga kushanda. Maererano nemutemo waNewton wegiravhiti, uye yakazvimiririra yakasimbiswa nemiedzo yakadai seiya yaEötvös nevatevedzeri vayo ona Eötvös kuyedza, kune hukuru hwekudonha wakasununguka inozivikanwawo seyakashata equivalency musimboti, kana kuenzana kwepasirese kweinertial uye passive-gravitational mass: nzira yemuviri wekuyedza mukudonha wakasununguka inoenderana chete nenzvimbo yayo uye nekumhanyisa kwekutanga, asi kwete pane chero chinhu chayo. Mufananidzo uri kurudyi unoratidza zvakaitwa naEinstein paaishandisa elevator: munhu anenge ari mukamuri duku rakavharwa, haakwanisi kuziva kuti kamuri racho riri munzvimbo ine simba rinokwevera zvinhu pasi here kana kuti riri muchadenga pane chitundumuseremusere chiri kukurumidza kusvika panzvimbo ine simba rinokwevera zvinhu pasi. Izvi zvinoratidza kuti... Mubvunzo: chii chinoita kuti objest idonhe?  <response>: simba rinokweva
