Chii tichimhanya muviri

Zvechivhurumukira ... Pfungwa rinowanzoshandiswa wefizikisi. Chii chinorehwa iri? Kana mukakumbira mubvunzo uyu kune nyore unogaramo, kazhinji, tichava kuwana mhinduro kuti tichimhanya muviri - zviri mumwe zvazvinoita (kusunda kana nokurohwa) akaratidza pamusoro muviri, saka kuti anokwanisa kuenda mune imwe kupiwa mirayiridzo. On wose, zvikuru zvakarurama tsananguro.

tichimhanya muviri - kutsunga nako isu kokutanga kuchikoro: Chidzidzo wefizikisi akatiratidza sei kumonera pasi diki rori uye akatarisana chesimbi bhora akadaro pamusoro pechiso zvokunamata. Ipapo isu akafunga kuti kuva nezvahunoita nesimba uye nguva yacho chaiko chaiyo. Kubva zvakawanika izvi uye vafunga, uye makore akawanda apfuura Ndakazvarwa pfungwa muviri sezvo zvechadenga kupomba sangano, kubatsirwa zvakananga pamusoro nokukurumidza uye guru chinhu.

Izwi iri zvesayenzi nezveshoko wokuFrance Rene Dekart. Zvino pakutanga XVII remakore. Masayendisiti tsanangura tichimhanya muviri kwete chete se "uwandu motokari." Mumashoko Descartes pachake, kana mumwe kutamira muviri collides nomumwe, nayo anorasikirwa zvakawanda kwayo simba sezvo anopa mumwe chinhu. zvinogona pamuviri, zvichienderana wefizikisi, hazvirevi kunyangarika, asi kungoti achichinjwa chinhu chimwe.

The chikuru hunhu ine kupomba muviri chiri dzidziso. Mune mamwe manzwi, ndiko vector uwandu. It anotevera kubva mashoko aya uye kuti muviri wose kufamba, ane chaicho tichimhanya.

Formula nokufumura mumwe chinhu kune umwe: p = mv, apo vs. - velocity muviri (vector uwandu), M - guru muviri.

Zvisinei, kuti tichimhanya muviri - kwete chete kwazvo kuti anosarudza kufamba. Nei vamwe muviri, kusiyana nevamwe, usaora naye kwenguva refu?

Mhinduro yomubvunzo uyu kwave chidzoke chimwe pfungwa - zvechivhurumukira iyo anosarudza mari uye nguva yokuwana yacho. Kunoita kuti kuziva kuti tichimhanya muviri mumwe kwenguva. zvairatidza anomiririra zvibereko inofambiswa (simba chaiyo) kwenguva ya chikumbiro chacho (nguva).

Chimwe chezvinhu zvikuru zvinoumba ari IT anochengeta nayo kuchinja, akagovera namahwindo hurongwa. Nemamwe mashoko, pasina zvimwe zvinofurira zviri zvinhu zviviri, pakati tichimhanya muviri icharamba akatsiga chero chaunoda. kuchengetedza kunogona kutorwa kufungwa mumamiriro ezvinhu umo kwokunze kukanganisa chinhu chiripo, asi ayo zvakamubaya Vector ndiyo 0. Uyewo, tichimhanya hakuzochinji panyaya apo matambudziko mauto aya, kana zvishoma anoita pamusoro muviri nguva pfupi zvikuru nguva (zvakadai apo bara).

Ndiwo mutemo uyu kuchengetedza makore anopfuura zana, iri haunted nokuda vavambi, vave kunetseka kusikwa chazezesa "isingaperi inofamba", sezvo ndiye iri hwaro pfungwa dzakadai ndege propulsion.

With Panyaya pokushandisa ruzivo pamusoro Chiitiko, sezvo tichimhanya muviri, kushandiswa kukura zvombo, zvombo uye zvitsva, kana kwete nokusingaperi, zvigadziriswe.
