Mitemo inokosha yemunhu

Chinyorwa Nezve Mitemo yeZviverengero Zvakakosha

Nhamba dzakakosha inhamba dzinowanikwa kuburikidza nekuyera kunosanganisira nhamba dzakakosha (dzinoverengwa pachishandiswa chekuyera) uye nhamba imwe chete inofungidzirwa.

Ngatitii tinoyera kureba kwechinhu tichishandisa ruler (Muganho wekururama kweruler i1 mm kana 0,1 cm) totaura mhedzisiro yacho nenhamba nhatu dzakakosha, semuenzaniso 4,55 cm. Kana kureba kwechinhu kuchiyerwa uchishandisa vernier caliper (Muganho wekururama kwevernier caliper i0,1 mm kana 0,01 cm) uye mhedzisiro yacho inotaurwa nenhamba ina dzakakosha, semuenzaniso 4,485 cm uye kana ikayerwa ne micrometer screw gauge (Muganho wekururama kwe micrometer screw gauge i0,01 mm kana 0,001 cm) uye mhedzisiro yacho inotaurwa nenhamba shanu dzakakosha, semuenzaniso 3,4845 cm. Izvi zvinoratidza kuti huwandu hwenhamba dzakakosha dzakataurwa semhedzisiro yekuyera hunoratidza kururama kwekuyera. Nhamba dzakakosha dzinogona kutaurwa, ndiko kwakanyatsojeka kwekuyera. Ehe, kuyera kureba kwechinhu ne micrometer screw gauge kwakarurama kupfuura ne vernier caliper neruler.

Mitemo yaKepler

Zvinyorwa zveMutemo zvaKepler

Unoyeuka here nguva yako yekutanga uchikwira mota (kwete pawaiva mucheche)? Pawaiva mumotokari inofamba, waiona sekunge miti kana zvivakwa zviri kufamba. Panguva iyoyo, waigona kunge waifunga kuti miti kana zvivakwa zviri kufamba, iwe nemotokari muchiri. Muchokwadi, iwe nemotokari maiva muchifamba, miti kana zvivakwa zvichiri kufamba. Isu tinonyatsoona kufamba uku kana kufamba kwenhema zuva rega rega. Mangwanani ega ega zuva "rinobuda" kumabvazuva, robva raenda kumadokero ro "doka" kumadokero masikati. Saizvozvowo, husiku, unowanzoona mwedzi uchifamba kubva kumabvazuva kuenda kumadokero. Wakambofunga here kana kufungidzira kuti zuva nemwedzi zvinofamba-famba pasi, pasi richiri kufamba?

Kufamba kwakatwasuka kwakafanana

Wakamboona ndege ichifamba panhandare yendege here? Kana zvisiri, tora nguva yekuenda kunhandare yendege muguta rako. Tarisa kufamba kwendege payava kuda kusimuka kana kuti yava kuda kumhara. Payava kuda kusimuka, ndege inotanga kufamba yakananga kubva panzvimbo yakamira uye kufamba kwayo kunokurumidza kusvika yabhururuka. Kusiyana neizvi, painomhara, kufamba kwendege, uko kwaitanga kwaimhanya zvikuru, kunononoka zvishoma nezvishoma. Kufamba kwendege panhandare yendege muenzaniso wekufamba kwakanangana nenzira yakatwasuka. Wakamboona muchero wakadonha kubva pahunde yawo ndokuwira pasi here? Kufamba kwemuchero kana chimwe chinhu chichidonha kubva pakakwirira kuenda pasi muenzaniso wekufamba kwakanangana nenzira yakatwasuka uye izvi zvinokurukurwa zvakadzama mu free fall . Unogona kupa mienzaniso yekufamba kwakanangana nenzira yakatwasuka muhupenyu hwezuva nezuva here?

Kufamba kwakafanana kwakatwasuka

Wakambotasva kana kutasva mudhudhudhu kana mota here? Ndinovimba kwete 🙂 hehe… kugara musango 😀 Kana mudhudhudhu kana mota iri kufambiswa ichifamba yakatwasuka uye kumhanya kwayo kuri kwakafanana, semuenzaniso 60 km/h saka mudhudhudhu kana mota iri kufamba yakatwasuka nekumhanya kwakafanana (GLB). Ngarava dzinofamba nechikepe kana ndege dzimwe nguva dzinoitawo GLB. Zviri nyore kuona zvinhu zvichifamba mumutsara wakatwasuka muhupenyu hwezuva nezuva asi zvakaoma kuona zvinhu zvichifamba GLB. Ungataura here muenzaniso weGLB wawakaona kana kufungidzira?

Kuwedzera kweVector

Kuwedzera mavector kunogona kuitwa nemifananidzo (kushandisa mifananidzo) uye nekuongorora (kushandisa kuverenga).

Kuwedzera kwemifananidzo yevector

Kuwedzera kwemifananidzo (graphical vector addition) kunosanganisira kuwedzera kwemifananidzo (vector addition) kunoitwa nekudhirowa mavectors anofanirwa kuwedzerwa pamwe nevector inobuda, ipapo saizi yevector inobuda inowanikwa nekuyera uchishandisa ruler.

Kufamba kwedenderedzwa

Hupenyu hwedu nhasi hwava nyore uye hwakasununguka nekuvapo kwemotokari dzine mavhiri, michina yemazuva ano yakaita semajenareta, michina yekugaya, mafeni, michina yekugeda uswa, michina yekupfapfaidza maruva nezvimwewo. Motokari dzine mavhiri dzakadai semabhasikoro, midhudhudhu, mota nendege hazvigone kufamba kana dzisina mavhiri kana mavhiri asingatenderere. Maherikoputa kana ndege hazvigone kubhururuka kana mapropeller adzo asingatenderere. Ngarava hadzigone kufamba nechikepe kana majenareta adzo asingatenderere. Husiku, imba inova rima uye hapana varaidzo kana jenareta kana gwenya risingashande. Zvinhu zvakawanda zvinoita kufamba kwedenderedzwa zuva rega rega. Kunyangwe tisingazvizivi, nyika yatinogara pairi, mwedzi unotivhenekera husiku, masatelaiti ekugadzira akadai semasatellite ekutaurirana anotumira mafungu emagetsi eterevhizheni, redhiyo, nharembozha, uye nhepfenyuro dzeinternet, anogara achitenderera, zvichinzi achifamba mudenderedzwa nguva dzese.

Kufamba kwakatwasuka

Zvinhu Zvakarurama Zvinofamba

Kufamba chinhu chatinogara tichiona muhupenyu hwezuva nezuva. Bazi refizikisi rinoongorora kufamba rinonzi mechanics. Bazi remakanika rinokurukura kuti chinhu chinofamba sei, pasina kufunga nezvechikonzero chekufamba, rinonzi kinematics . Kusiyana neizvi, bazi remakanika rinokurukura zvinokonzera kufamba uye rinotsanangura kuti nei zvinhu zvichifamba sezvazvinoita rinonzi dynamics. Munyaya iyi, chinhu chega chega chinofamba chinoonekwa sekunge chiri chidimbu kana poindi (.). Zvinhu zvinofamba zvinoonekwa semapoindi kuti zvive nyore kuongorora kwedu. Fungidzira kana poindi ichifamba mumutsara wakatwasuka, ipapo nzira yayo ichaumba mutsetse wakatwasuka.

Kufamba kwemahara kwekudonha

Zvinhu zveMafashamo eMatsutso Emahara

Munguva dzekare, kufamba kwezvinhu zvichidonha pasi kwaive nyaya inonakidza zvikuru muuzivi hwechisikigo. Muzivi Aristotle akamboti zvinhu zvine huremu hwakakura zvinodonha nekukurumidza kupfuura zvinhu zvakareruka. Mafungiro aAristotle akapesvedzera maonero evanhu vakararama Galileo asati asvika, avo vaitenda kuti zvinhu zvine huremu hwakakura zvinodonha nekukurumidza kupfuura zvinhu zvakareruka uye kuti kumhanya kwechinhu kunoenderana nehuremu hwacho. Pamwe usati wadzidza nyaya iyi, waifungawo zvakafanana.

Kufamba kweparabolic

Kufamba kweparabolic kana kufamba kweprojectile rudzi rwekufamba uko chinhu chinotanga chapihwa velocity yekutanga uye kufamba kwacho kunokanganiswa zvachose nesimba regiravhiti. Kufamba kweprojectile kufamba kwemativi maviri, musanganiswa wekufamba kwakatwasuka nekwakatwasuka, kusiyana nekufamba kwakatwasuka kana kuwa kwakasununguka, izvo zviri kufamba kwemativi rimwe chete.

Galileo akatsanangura kuti kufamba kweparabolic kunogona kunzwisiswa nekutarisa zvikamu zvekufamba zvakamira uye zvakatwasuka zvakasiyana. Kukurumidza kwegiravhiti kunoshanda chete munzira yakatwasuka, kwete munzira yakatwasuka. Nokudaro, chikamu chakatwasuka chekufamba kweprojectile chinoonekwa sekufamba kwakafanana kwemutsara , uye chikamu chakatwasuka chekufamba kweparabolic chinoonekwa sekuwa kwakasununguka.

Mutemo waNewton wesimba rinokwevera pasi

Mutemo waNewton weZvinhu Zvinokwevera Simba Pasi

Sei muchero uchidonha kana kufamba uchienda pamusoro peNyika mushure mekunge wabviswa pahunde yawo? Mitemo yaNewton inoti kana muchero uchifamba, panofanira kunge paine simba rinoushanda. Simba rinoita kuti chinhu chiwire zvakasununguka pamusoro peNyika rinonzi simba regiravhiti rePasi.

Dambudziko rezvinhu zvinodonha zvine chekuita negiravhiti, rauri kudzidza izvozvi, rakatanga kufungwa nezvaro uye rakadzidzwa nemusayendisiti wekuBritain mushakabvu Isaac Newton. Zvinetso zvaNewton zvinotangira kuGreece yekare. Pane matambudziko maviri makuru ayo maGiriki akanga achiferefeta kare kare Newton asati aberekwa.
