Translational zoyenda

Kodi gulu mwapang'onopang'ono? Sukulu buku bwino Anatipeza ife pa funso limeneli: patsogolo zoyenda za thupi (Note, abwino chinthu - "thupi olimba mwamtheradi" - Att, wopanda mtundu uliwonse kotheka kuti opunduka) - ndi gulu limene mzere aliyense molunjika kukopedwa amakhalabe kufanana yokha pa gulu lonse mu thupi (Att).

Yankho zikuoneka kuti zochuluka. Tanthauzo wapatsidwa, ndipo pa cholinga mokomera kinematics zoyenda translational. Poyamba, ili ndi vuto la zosavuta yunifolomu rectilinear zoyenda, ndiye - (! Ndipo mosamalitsa liniya) zovuta ndiponso wosangalatsa chifukwa kufunsira maganizo ravnoperemennoe kayendedwe, chitsanzo omveka amene ali kugwa ufulu wa matupi. Mu gawo ili, mwana pokhala yodziwa dongosolo chidwi, ananena motere:

1. Njira anayenda ndi thupi pa intervals motsatizana akukhudzana monga mabwalo a manambala zachilengedwe: 1: 4: 9: 16 ...

ndi

2. Njira anayendayenda thupi pa intervals motsatizana ofanana nthawi, ndi chilamulira chikhalidwe monga mndandanda wa manambala wosamvetseka: 1: 3: 5, 9 ...

Kuthetsa mavuto zimachitika mwa chofunika zida methodological ndi masamu, njira chidwi reversibility za kayendedwe, imene deta onse komaliza ndi koyamba ndi mosemphanitsa (kayendedwe monga kumachitika zosiyana, ndi kuwerengetsa a). Mphamvu ya osiyanitsidwa wa yomweyo mathamangidwe vekitala ya ndondomeko pa mfundo zonse kunjira yolunjika kusintha malangizo ake zikutsatiridwa yekha malangizo a mathamangitsidwe vekitala, chibadwa kugwirizana ndi vekitala chotsatira cha mphamvu zonse ntchito kwa thupi.

The "Mphamvu za liniya zoyenda" komanso kinematics, ndi zolemba akusonyeza kuti kayendedwe ka thupi ndi mosamalitsa mwapang'onopang'ono, popanda kutembenuka olamulira aliyense ndi mavuto anali. Ndi chifukwa cha zinthu izi chisanadze mwachindunji akhoza adatayidwira mu kukula kwa thupi ntchito, kuganizira m'malo abwino chinthu - zakuthupi mfundo (MT) ndi spatially coincident ndi pakati yokoka (CG) za thupi. Komabe, MT malo poyamba analowa mu "Kinematics" chifukwa nthawi imene kukula kwa thupi kunyalanyaza poyerekeza ndi kutalika njira.

malamulo Conservation zinachitikira zoyenda rectilinear Komanso ankaona m'mikhalidwe pamene ife umboni ku kasinthasintha zotheka kwa thupi mwa kuika gulu lake mwapang'onopang'ono (tikanatha kuonedwa reciprocal kusintha kwa kayendedwe rotational mu mphamvu mphamvu za kayendedwe ya kutsogolo ndi chigamulocho)

Mwachidule, nkhani mu sayansi sukulu patsogolo kayendedwe (pang'onong'ono zinali choncho wapadera wa zoyenda kudutsa mzere wolunjika!) Amatipatsa chakudya ndithu kwa lingaliro ndi kafukufuku ongolankhula. Inu simungakhoze kunena za gawo experimental za Maphunziro kuti Maphunziro a gulu pang'onopang'ono. Mkhalidwe khwekhwe experimental imangokhala kwina m'makalasi kwambiri.

Ngakhale nkhani yapadera ya kutsogolo zoyenda amaphunzira makamaka chiphunzitso. N'zoona kuti si chidole, makina Atwood wolemera ndipo mwamsanga sangathenso ophunzira Nditchimo, pokhala kalekale anaika penapake kumbali kutali a sayansi nduna. Chionetsero mayunitsi monga kutsetsereka pamodzi waya anatambasula katundu palimodzi tanthauzo, chifukwa kutsanzira ya kudzidalira ngati zoyenda rectilinear, amene si lofanana ndi chisonyezo translational zinachitikira ambiri. Kodi ndiye akhoza amalangiza? Kufufuza Only kafukufuku kwenikweni ozungulira kupitirira zasayansi sayansi ntchito nzeru chilengedwe!

Lotengeka ndi buku chitsanzo cha Ferris gudumu ( "Mdyerekezi Wheel"), m'mphepete ndi amene masipoko kuchita gulu rotational, ndi kuonerera misasa ikuyenda likunena (! Ngakhale bwalo) otsimikizira kuti vutoli kayendedwe Att (ndi pafupifupi - thupi lenileni) kungakhale osati zolungama, komanso kukhala njira iliyonse yokhota kumapeto (mu izi kufanizitsa mlandu chikugwirizana ndi njira yodutsamo za kayendedwe rotational wa MT).

Lingaliro la kupeza milandu kagulu kofufuza pa malo osewerera (mu mode experimental osati ongolankhula mtsutso) "chagona chapafupi pomwepo" ndi "Ferris wheel". Popeza kuti malo osewerera pa, tidzatha kufufuza ngati zotsalira ikufanana yokha mwachindunji (yoyerekeza ndi nthambi iliyonse kapena woonda lath) cha thupi zoyenda pa mitundu yonse ya alili, roundabouts ndi simulators. Zikuonekeratu kuti padzakhala mwapang'onopang'ono ngati ufulu kugwa kwa thupi zopanda moyo, anang'amba pang'ono "kukwera chimango".

Kuonetsetsa kuti translational koyera kayendedwe nthawi zambiri amapezeka mu chikhalidwe monga chitsanzo chapadera - patsogolo liniya zoyenda, ife kuyatsa mtima akhoza chitani zinthu ongolankhula ya m'buku la kusukulu.
