Kinetic simba: pfungwa

The kinetic simba - ndiko, kubudikidza tsanangudzo, mutengo akaenzana hafu mukanyiwa of zvinofamba muviri, kane yaiungana pamusoro velocity muviri. Ichi - chimwe chezvinhu zvinokosha mashoko makanika ano. Muchidimbu kuisa, ndiwo simba inofamba, kana kusiyana zvachose simba uye vamwe simba. Asi musimboti haisi vaiona zvizere nesayenzi yemazuva ano.

The kinetic simba (kubva Gr Kinema -. Movement) muviri vachingotya kutadza kufamba ndiko razero. Kazhinji, ukoshi ichi hazvirevi chete chokuita guru uye nokukurumidza. Saka, maererano imwe tsananguro, kinetic simba - ibasa rinoitwa pane imwe nokukurumidza. It unotaurwa joules.

The kinetic simba wegadziriro - ndiyo mari, iyo kufanana mwero nerimwe ayo pfungwa.

Zvinonzi munyaya kufambira mberi, uye kutenderera. nyaya yokutanga watopiwa akatsanangura zvakadzama pamusoro, ndiko - hafu mukanyiwa ane chinhu kane kwayo velocity akaenzana. A muviri kutenderera kinetic simba rinomiririrwa sezvo vakaverenga kinetic masimba nerimwe zvepakutanga vhoriyamu muviri. Kana sezvo kukosha nguva inertia kane pachivara kuti chisina kutsetseka velocity yakakamurwa vaviri.

Kufunga paine hwakasimba kuti riri kufamba uchitenderera akabatana mira ichifamba therethrough. chinhu ichi chinogona kukamurwa diki vhoriyamu okunze, imwe neimwe ine zvayo zvokuvamba guru pachavo. Around munhu wakaiswa akabatana inofamba zvinoita muviri pasi kukurukurwa. Pakazoti nerimwe zvokutanga mavhoriyamu rinotsanangura denderedzwa chaienzanirana nharaunda. Same chisina kutsetseka kumhanya kuti kutenderera. Naizvozvo kinetic simba muviri - ndiyo vakaverenga kinetic masimba ose ayo zvokutanga, kungopembera akabatana bhuku. A Yokudzidza shanduro yemaitiro - hafu zvinobikwa mativi ose chisina kutsetseka velocity uye panguva inertia.

Mune zvimwe zviitiko, kinetic simba - ndiyo mari uye translational uye rotational simba. Somuenzaniso, zvishoma nezvishoma mumatope pasi pasina zvishoma nezvishoma mumatope achitevedza vachida humburumbira mutsetse. Kufambira mberi, izvozvo anoita kufambira mberi, asi panguva iyoyo akanga unotuma kumativi ayo akabatana.

Mumwe zvinoumba ari kinetic nesimba kutenderera - ndiwo Nguva inertia, izvo pamusoro uye kukurukurwa. It kunobva zvachose body mass, uyewo kuparadzirwa kwayo toreva akabatana kuti kutenderera. Chii? Zviri chiyero inertia pamusoro akabatana inofamba uyewo ari mberi sangano iri nechiyero inertia chevanhu vakawanda. Ichi chinhu chakakosha kwazvo ukoshi. Nguva inertia, zvikuru zvakaoma kuunza muviri ari rotational mamiriro. Chisina kutsetseka velocity rinotsanangura pakukurumidza zvinofamba zvikukutu kumativi ayo akabatana. The chikwata ndiyo rad / s. The chisina kutsetseka velocity ndiyo nhamba iri kutenderera yorusvingo kusvikira urefu nguva iyo yorusvingo ichi inopfuura ari kutenderera chinhu.

Theorem pakati kinetic simba inogona akagadzira sezvizvi: basa simba nomuuyo rinoshandisirwa imwe muviri, kwakafanana nokuchinja mune kinetic simba kwomuviri.
