Zvokuimba kufamba - zvose nezvazvo

Zvaizoratidza sokuti shoko rokuti "zvokuimba kufamba" anotaura pacharo. Nyaya yaiva imwe nguva, uye pashure penguva yakati akasangana mumwe - waiva sangano. Zvisinei, havasi vose nyore. Munguva izwi, kumusoro, nhema zvakadzama zvinoreva.

Kutamira kubva anongedze pfungwa haisi nguva imwe, uye imwe nguva. Uye kwete kamwe kubva pfungwa A kukuratidza B, uye vamwe pemitsara. kufamba muviri mutsetse akadana trajectory uye kureba - vachipfuura. Tsanangura maitiro muviri wayo trajectory kazhinji chaizvo basa rakaoma. Asi kana tikashandisa mufananidzo muviri muchadenga achibatsirwa Coordonatele uye nguva, ichava mutemo inofamba.

Zvino mubvunzo unotevera iri - zvakanaka sei akaita zvokuimba kufamba? Kana apo vose vari kutamira chete pfungwa chinhu, zvichava mberi. Zvisinei, kana, ake muviri kubvongodzwa pfungwa dziri pamusoro denderedzwa, sangano iri rotational. Pano isu watova hunhu zvokuimba inofamba, uye kwete mumwe.

Basa wefizikisi harisi chete rondedzero nedanho kufamba, asiwo achifanotaura kupi muviri yaizova pane imwe nguva. Zvisinei, kushandisa mutemo uyu inofamba uye ayo unhu, tinofanira kuwana pokutangira zvakanyeverwa kubhadhara vose vachaitwa. Kamwe kwakanyorwa kunotsanangurwa, isu achapedzisa hurongwa panotaurwa umo munogona kutsanangura chero zvokuimba kufamba.

Kuchinjwa kunoitika pamusoro kutanga pfungwa rinoronga hurongwa kana, mune mamwe mazwi, bhuku puranga. Point chakangomuka anogona kusarudzwa pamadiro, uye change achitandadza nezvezvinotaurwa rondedzero inofamba anogona kutsausa vamwe. Nokudaro, hatina takatsunga kuti zvokuimba inofamba ihama. Aya zviri relativity yakanga akagadzira pedyo Galileo.

Kuti kutsanangura quantitatively yose nedanho kubvongodzwa, inoramba achiri kupinda chinhu chakadai nokukurumidza. Pasi payo translational inofamba ndiyo nhamba akakwana kufamba uye nguva yakawandisa kufamba ichi. In Kana apo mwero haachinji mirayiridzo uye kukosha kwayo, sangano iri kunyange uye kururamiswa. Kana zvinodiwa izvi zvikasaitwa - sangano achava gogonera.

Zvichireva kukurumidza - vanokoshesawo hama, uye kuvimba nenhungamiro wayo, i.e., Izvi vector uwandu. Kana chitima kunoita hama kuti pose paNyika nokukurumidza V1 uye zvirimo nenzira nechitima uri mufambi ane velocity V2, ipapo panyaya nyika mufambi kuchaita vari kumhanya V1 + V2. Asi kana iye ichatsedukira pamusoro inofamba iri chitima, ipapo noruremekedzo pasi, iye kuchaita ichimhanya V1 - V2.

Kupedza tsanangudzo sangano nerwodzi chikwata inofanira kushandiswa kuuya unhu. Time kunoyerwa seconds, kure akafamba - mu metres, zvakanaka, nokukurumidza, ukuwo, mune mamita muzana wechipiri.

Above takakurukura pfungwa zvokuimba kufamba kubva pfungwa nemaonero wefizikisi. Zvisinei, pfungwa iyi inowanikwa dzimwe sayenzi. Saka, shoko rokuti "zvokuimba kufamba kwevanhu," anoshanda ari socio-upfumi nhamba. Chimwe zita iri izwi - yokutama. Inosanganisira kwevanhu kuburikidza munharaunda wacho (nyika, zvokuvhoterwa, maruwa), uye sangano kwakadaro chokuita neshanduko dzokugara.

Mashoko ane pfungwa dzakadaro anonzi, sezvo zvokuimba inofamba, uye rondedzero zvachiri. The ehupfumi inofamba - trajectory, kumhanya, daro - uye kupa pfungwa mukuru relativity inofamba. Uyewo akataura kuti kushandisa zvakafanana pfungwa dzimwe sayenzi.
