Mofulumira yokoka

Tchulani mfundo yokoka mathamangitsidwe nthawi zambiri limodzi ndi zitsanzo komanso zatsopano za mabuku, imene zinthu zosiyanasiyana malinga ndi kulemera (makamaka, cholembera ndi ndalama) inatha ku kutalika chomwecho. Zikuonekeratu mwamtheradi kuti zinthu kugwa pansi pa intervals osiyana nthawi (cholembera kotero ambiri akhoza kugwa). Choncho, ufulu kugwa kwa matupi kosamugonjera ulamuliro imodzi yokha yeniyeni. Komabe, n'zodziŵika yokha tsopano, nthawi ina kale, ankafunika kuchita zinthu zatsopano kuti atsimikizire zimenezi. Akatswiri ndikoyenera kukhulupirira kuti mu kugwa kwa matupi kuyendetsa mphamvu imagwira m'gulu lawo ndipo monga Motero, mlingo wa gulu choimirira. Pambuyo zatsopano osachepera wotchuka ndi machubu galasi ili mkati ndalama ndi cholembera (chiyeletso cha zimenezo). mpweya anali amawapopa kuchokera machubu, pambuyo imene anali mwamphamvu plugged. Kodi anadabwa ofufuza, ndipo pamene cholembera ndi ndalama, ngakhale zolemera mwachionekere osiyana kugwa pa liwiro.

Zimenezi zinali maziko osati kwa chilengedwe cha mfundo mathamangitsidwe yokoka (USP), komanso amati ufulu kugwa (ie kugwa thupi, amene si anakhudzidwa ndi mphamvu iliyonse lotsutsa) n'chotheka mu zingalowe m'malo a. Mu mlengalenga, yemwe ndi gwero la kukana, onse matupi kusuntha ndi mathamangitsidwe.

Kotero lingaliro la mathamangitsidwe yokoka, kupeza tanthauzo zotsatirazi:

• matupi kugwa enawo mchikakamizo cha mphamvu za anyamata a Dziko Lapansi.

Mfundo imeneyi anali kupereka pa lemba la Greek zilembo ga (PVCs).

Pamaziko a zatsopano izi, zinadziwika kuti USP ndendende khalidwe la Earth, popeza tikudziwa kuti dziko ndi mphamvu kuti amakopeka pamwamba pa matupi onse. Panali Koma funso lina: mmene kuyeza mtengo komanso zimene wofanana.

Yankho ku funso loyamba mmalo msanga: Asayansi ndi udindo wapadera kujambula lokhazikika kwa thupi pamene kugwa mu zingalowe m'malo mwa malo pa intervals osiyana nthawi. Kunapezeka chinthu chidwi: matupi onse mu malo anapatsidwa a Dziko Lapansi kugwa ndi mathamangitsidwe yemweyo, amene Komabe, osiyanasiyana malingana ndi malo enieni padzikoli. Kutalika kwa thupi anayamba kusuntha, zilibe kanthu: zingakhale 10, 100 kapena 200 meters.

Tinapeza: mathamangitsidwe ufulu kugwa Padziko Lapansi pafupifupi 9,8 N / kg. Ndipotu chomwecho, phindu angakhale mu osiyanasiyana kuchokera 9,78 N / kg kuti 9,83 N / kg. Kusiyana kumeneku (ngakhale ang'ono mu maso a layman) limafotokoza mmene mawonekedwe a Dziko Lapansi (zomwe siziri chimodzimodzi ozungulira, koma flattened mizati), komanso tsiku kasinthasintha wa Earth dzuwa. Childs, phindu avareji udindo anatengedwa - 9,8 N / kg pa ambirimbiri - anamaliza 10 N / kg.

ga = 9,8 N / kg

Against maziko a deta limasonyeza kuti mathamangitsidwe chifukwa yokoka pa maplaneti ena ndi osiyana kwake pa Dziko Lapansi. Asayansi anazindikira kuti tingasonyezere ndi chilinganizo zotsatirazi:

ga = G × M dziko / (R dziko) (2)

Mawu osavuta: G (ndi Mphamvu zonse (6,67 • 10 (-11) m2 / S2 ∙ kg)) ndi kuchulukitsa ndi M - misa dziko lapansili, akufufuta R - dzikoli utali wozungulira lofanana mbali zonse. Mwachitsanzo, tingapeze mathamangitsidwe yokoka pa Moon. Podziwa kuti misa ndi wofanana 7.3477 * 10 (22) makilogalamu ndi amene utali wozungulira - 1737,10 Km, ife tikupeza kuti USP = 1,62 N / kg. Monga taonera, mathamangitsidwe mu mapulaneti awiri ndi wosiyana kwambiri ndi mzake. Makamaka mu dziko ndi pafupifupi nthawi 6 kwambiri! Mwachidule, mwezi atamukoka zinthu zimene padziko, ndi mphamvu ya nthawi zosakwana 6 kuposa Dziko Lapansi. Ndicho chifukwa chombo pa mwezi, yomwe timaona pa TV, monga kukhala kosavuta. Ndipotu, kuonda (osati misa!). Chifukwa ndi zotsatira zosangalatsa ngati kudumpha mamita angapo, kumverera kwa zouluka ndi patsogolo yaitali.
