Kuti vanodzidza kinematics? Pfungwa nokukura uye basa

Kuti vanodzidza kinematics? With mubvunzo uyu anenge pakarepo nezvakaonekwa vadzidzi giredhi rechinomwe, chete kubva pakudzidza wefizikisi. Nhasi isu kutaura chokwadi kuti kudzidza kinematics izvo pfungwa mairi zvinokosha. Funga nyaya uye zvinokosha ichi bazi wefizikisi, tichatema kunzwisisa chii payakavakirwa rinogona kushandiswa uye kana kunofanira kuitwa.

Chii kudzidza Vanamakanika, kinematics, simba?

Chokutanga, ngatiite, saka kutaura, kuti demarcation mutsetse pakati izvi pfungwa nhatu. Mechanics mumwe mumuviri partitions. Pairi unogona kutaura kuti iye anga achidzidza hurongwa pokuenda zvitunha mitemo. Asi tsanangudzo dzakadaro muverengi angawana uye zvino, kana totaura simba pamusoro kinematics.

Saka chii musiyano?

Ngatiedzei kutanga kubata chokwadi kuti vanodzidza kinematics uye kuti sayenzi iyi. Kutaura zvazviri, kinematics kumbobvira akazvimirira. Hakuna mumwe kunze Vanamakanika chikamu. All vatatu: kinematics, simba uye statics. zvikamu zvose izvi zvitatu zvakafanana zvemaziso Mapato, kureva kudzidza kukurukurirana yemiviri uye kunyanya avo kufamba. Zvisinei, mumwe nomumwe wavo ane chaizvo unhu.

The subtleties pamusoro zvikamu izvi

Kinematics zvimwe ndiyo chikamu inonakidza zvikuru ouzivi matambudziko. Zvakasiyana-siyana combinatorial dambudziko here yakakura kwakaita kuti urongwa kwavo - zvose anova rapakona pairi kuvakira zvinobatsira kinematics. Panzira, kunyange kuvhura miedzo kugadzirira bvunzo mugiredhi rechi9, takanga pakarepo kukwanisa vanogumburwa mienzaniso iri nyore. Achiti kuti kudzidza kinematics, tinogona kutaura kuti anoona zvinoitwa inofamba miviri pasina kufungisisa mauto mukukurukurirana.

Zvishoma kuoma zvakadaro pamwe chikamu makanika, simba rinomutsa. Rinotaurawo anofunga inofamba yemiviri uye tsamba tsika kuoneka. Izvi Somuenzaniso, kumhanya, kure, nguva. Asi pane uye dzinoverengeka rechitatu-party mazwi. Pano mitemo inofamba nyore usaswedera kure, zvakakodzera kufunga zvokuimba gadziriro, kufungisisa mauto ndikaita imwe muviri. Asi ongororo vane kunofambira mberi zvakanyatsoenzana nemitemo zvemaziso gadziriro. Pane kuonekwa kwete chete muviri uye maoko uye zvimwe zvinhu.

Chii hwaro kinematics?

Saka, takaona kuti kinematics inodzidza inofamba miviri pasina chokuita nemauto kuita pamusoro zvinhu pfungwa. Asi chii chaiita chino, hurongwa, asi mitemo chinokosha? Pfungwa uye tsanangudzo - chokwadi chakanaka, asi chaizvoizvo imwe dzidziso, isu havazokwanisi kushandisa kugadzirisa matambudziko. Pamwero muduku zvikuru, kuti vabudirire zvakanaka mugumisiro kana zvaitika, tichafanira kushandisa Masvomhu. Uye kuita izvi, ngatitangei kukurira tsika kuti kuchange kuripo.

Huru zvakawanda wakashandiswa kinematics matambudziko

Chokutanga, tinofanira kuyeuchidza vaverengi kuti vanogona kuva tsika rinoshamisa. Ngatitange aine ukoshi nyore yatinoti spacing. Chinhu scalar uwandu. Kureva kuva chete imwe ukoshi. mamita matatu, iyo akakungurutsira bhora. 25 metres kuti chikepe mutambi. makiromita gumi vaifamba munhu kuti zuva rose. All ichi - the kusanganiswa netsika yatinoti spacing.

A shoma akasiyana zvakadaro nokumhanya uye kumhanyisa vari kinematics (uye general) vane Dual hunhu. Kudivi rimwe, tinogona kupa nhamba kukosha pakukurumidza. Ngazvive mashanu, gumi, makumi maviri metres muzana wechipiri. Asi nokukurumidza uye mirayiridzo iri. It rinobatana kutungamirirwa kufamba muviri, zviri pachena. Saizvozvowo, ndizvo chete kumhanyisa. Zvisinei, nokukurumidza uye kumhanyisa ringatsaudzirwa kwakasiyana-siyana. Panyaya iyi, muviri zvishoma pasi. Fungidzira kuti motokari iri kutotanga kuenda, pamwe kunhonga ose wechipiri nokukurumidza. The velocity uye kumhanyisa imwe nhungamiro, naro kumhanya muviri kunowedzera ose wechipiri. Asi kana paine deceleration pamusoro Vector tinotungamirirwa kwakasiyana-siyana.

Kinematics - chikamu makanika kuti vanodzidza inofamba miviri. Asi chii chingadzidzwa, kana hatishandisi nguva ino penguva? Hezvinoi - mumwe ukoshi kushandiswa kugadzirisa zvinetso uye tsanangura mitemo wefizikisi muchikamu chino. It, pamwe kure, kumhanya uye kumhanyisa, zvirimo dzimwe Masvomhu, inonyanyoshandiswa kushandiswa kutyaira sarudzo. Ngatimboonai imwe kumbonyanya nyore basa panyaya iyi, kuti pakupedzisira kusimbisa mune tsika kwokutanga munyaya vakagamuchira dzidziso.

Kuti asimbise zvechadenga motokari iri yoga-mita zana pakureba hwakakwana mugwagwa. Zvinozivikanwa kuti ayo kumhanyisa yakaenzana mamita mashanu chete wechipiri akaenzana. Wanai nguva yakadii kuti motokari vanogona kuenda kuti daro, kufungisisa chokwadi chokuti inofamba rinotanga kubva zororo.

Saka, sezvo kinematics - bazi makanika kuti kudzidza mitemo inofamba miviri, tichashandisa runoenzanirana Masvomhu. Kazhinji, zvinoita sokunge _{ichi: S = V O T + (} -) (pa ^ 2) / 2. Asi tinofanira tiite mabasa edu kushandura mhuka. Zvinonzi sangano rinotanga kubva standstill. Saka, pakutanga velocity ndiyo razero. Somugumisiro, zvinobikwa nokukurumidza panguva V _O T ndiyo razero. Sezvo motokari Inowedzera, nokuti nzira yemaitiro yaingowanikwa "+" chiratidzo. Somugumisiro, zvinotora zvinotevera chimiro: S = (pa ^ 2) / 2.

Chinotevera chinhu patinorumbidza yaiungana nguva. Kuti aite izvi, isu muwande mativi mukana wokuti vanhu vanga ichi pamusoro deuce kuti nyorazve panzvimbo. Zvino unofanira kugovera kaviri daro kuti kumhanyisa. Kwokupedzisira Danho yaizova kuratidza yaiungana pamudzi okuti. Zvakanaka, tava kuti nzira nyore. Zvino hunoratidzika: T = sqrt (2S / a). It chete anoramba kuti kuisa nhamba. Somugumisiro tinoona kuti motokari kwapfuura kure wakapiwa kwenguva akaenzana anenge 6.32 seconds.
