Amaqiniso ethakazelisayo physics. Physics zonke izinto ezisizungezile: amaqiniso athakazelisayo

Yini isayensi amumethe amaqiniso ezithakazelisayo? Physics! Ibanga 7 - yisikhathi lapho abafundi baqale ukufunda yona. Ukuze sina nodaba akuzange kubonakale akujabulisi, sinikeza ukuqala isifundo fun amaqiniso.

Kungani rainbow imibala eziyisikhombisa

Amaqiniso ethakazelisayo physics ingathinta ngisho uthingo! Inombolo imibala kulo kuchazwe Isaak Nyuton. Lo mkhuba uthingo, ethanda kakhulu u-Aristotle, futhi Persian isazi essence kwasivulela emuva 13-14 leminyaka. Noma kunjalo, siholwa incazelo rainbow, lapho uNewton benza e "yokukhanya" lakhe 1704. Yasho umbala usebenzisa nezibhebhe ingilazi.

Uma sihlole rainbow, ungabona kanjani imibala ageleze kahle zibe omunye komunye, ukwakha lenqwaba imibala. Futhi Newton ekucaleni esabiwe emihlanu kuphela eziyisisekelo: onsomi, oluhlaza okwesibhakabhaka, oluhlaza, ophuzi, obomvu. Kodwa usosayensi kwadingeka abanothando ukubhula, futhi ngenxa yalokho wayefuna ukuletha inani imibala sibalo ezingaqondakali "isikhombisa". Wanezela ukuthi incazelo rainbow namanje ezimbili imibala - orange blue. Ngakho ngithola uthingo eziyisikhombisa elinombala onjengomlilo.

ewuketshezi

Physics - elisizungezile. Amaqiniso ethakazelisayo kungase kusimangaze, ngisho nalapho kuziwa ezifana nezinto ezijwayelekile njengoba amanzi avamile. Sonke ejwayele ecabanga ukuthi uketshezi akanayo umumo, elikushoyo ngisho incwadi yesikole physics! Nokho, akuyona. Yemvelo ewuketshezi - ibhola.

Ukuphakama Eiffel Tower

Uyini ukuphakama ngqo i-Eiffel Tower? Futhi kuncike sezulu! Iqiniso lokuthi ukuphakama umbhoshongo kuyahlukana ngokuya kakhulu ngendlela 12 amasentimitha. Lokhu kuvela yokuthi ilanga lishisa, solar isakhiwo evuthayo, futhi izinga lokushisa imishayo bengase bazikhandlele 40 degrees Celsius. Futhi njengoba yaziwa, izinto kungenziwa landiswa ngaphansi lokushisa eliphezulu.

ososayensi ozinikele

Amaqiniso ethakazelisayo izazi sesayensi yemvelo abakwazi kuphela fun, kodwa futhi ukhulume ukuzinikezela kwabo nokuzinikela umsebenzi wakhe ozithandayo. Phakathi nesifundo we kagesi arc physics Vasily Petrov isuswe ungqimba phezulu isikhumba kalula ukuzizwa imisinga ababuthakathaka.

Futhi Isaak Nyuton yethulwa kuleli amehlo ayo probe ukuqonda ubunjalo umbono. Ososayensi bakholelwa ukuthi sibona ngoba ingcindezi ukukhanya kuyi-retina.

ubishi

Amaqiniso ethakazelisayo physics kungasiza ukuqonda izakhiwo ezinjalo izinto bezijabulisa sifana nodaka olubishayo. Ziyakwazi uketshezi non-Newton. Umuntu noma isilwane angeke ugxumele esihlabathini esimanzi esiwukuphila ngokuphelele ngenxa viscosity high, kodwa futhi ukuphuma kunzima kakhulu. Ukuze uthole nonyawo lwakho aphume esihlabathini esimanzi esiwukuphila, kudingeka senze umzamo ufana ngokuvuswa imoto.

Kuyinto engenakwenzeka minza, kodwa ingozi ekuphileni amanzi emzimbeni, ilanga, amagagasi. Lapho injected kancane kancane ogibeni lwaleli kudingeka amanga emuva bese ulinda usizo.

isivinini hypersonic

Uyazi, sasinjani kudivayisi ngowokuqala ukuphula isithiyo umsindo? isiswebhu Ordinary sikamalusi. Chofoza izinkomo okwesabisayo akulutho like cotton ekunqobeni ijubane umsindo! It ahlangabezana ichopho uhamba isiswebhu ngokukhulu ukushesha kangangokuba kwakha wave shock emoyeni. Kwenzeka okufanayo nge indiza endiza ngesivinini leSupersonic.

ikhasi lesikhwama sasekhaya sphere

Amaqiniso ethakazelisayo physics kanye nesimo izimbobo black kukhona kangangokuthi ngezinye izikhathi akunakwenzeka ukuba nokuyicabanga nokufaka theory izibalo. Kuyaziwa ukuthi zokukhanya zenziwa yizo izinhlayiyana eziningi zokukhanya. Falling ngaphansi kwethonya adonsela phansi ukwakha ukuhlelwa kwesikhala sezinhlamvu izinhlayiyana eziningi zokukhanya arc, endaweni lapho baqala orbit. Ososayensi bakholelwa ukuthi uma ufaka umuntu e sphere ikhasi lesikhwama sasekhaya, uyabona emuva sakhe.

scotch

Cishe akunakwenzeka ukuthi unwound itheyiphu esikhaleni nje, kodwa abacwaningi lab bakhe benza. Futhi sithole ukuthi kukhona ngemisebe ayabonakala futhi-X ray ngesikhathi unwinding. amandla-X-ray kangangokuthi ngisho ikuvumela ukuba awuthathe izithombe zomzimba! Futhi yingakho lokhu okwenzekayo - imfihlakalo. A nomphumela ofanayo kungabonakala nasemkhakheni ukubhujiswa izibopho quin ku crystal. Kodwa into - akukho isakhiwo crystal ku ngethephu enamathelayo asipheli. Ngakho ososayensi kukhuphukele nomunye incazelo. Kufanele ungesabi sokuphumula tape ekhaya - emoyeni, kwenzeka kungekho ngemisebe.

Ukuhlolwa abantu

Ngo 1746, isazi sesayensi yemvelo French futhi, kanyekanye, Jean-Antuan Nolle umpristi uphenyo ubunjalo kagesi. Usosayensi wanquma ukuthola ukuthi yini ijubane i kagesi. Yilokho nje ukuthi kwenziwa kanjani emzini wezindela ...

Zemvelo ababemenyelwe uzizamele izindela 200 wajoyina ngezinkemba zensimbi ucingo khulula battery ku ayengebona we ayesanda kuklanywa Leyden izimbiza (zinjalo capacitors lokuqala). Zonke izindela basabela isiteleka ngesikhathi esifanayo, futhi lokhu kuye kwenza kwaba sobala ukuthi izinga ukugeleza kuphezulu kakhulu.

Losers elihlakaniphile

Amaqiniso ethakazelisayo nokuphila zesayensi Ungahambisa amathemba engamanga KOKUCIJILE OKUBHEKE PHEZULU. legend uhamba phakathi abafundi budedengu ukuthi Einstein odumile kwaba Achiever Okuyınqo, wayengayazi Tibalo kanye nebudlelwane lobukhona zonke flunked uhlolo lokugcina. Futhi akukho lutho, waba kuzisebenzi zomhlaba usosayensi odumile. Thina khawuleza ukudanisa: U-Albert Einstein waqala ukubonisa emangalisayo ikhono zezibalo esemncane futhi wayenolwazi, eyedlula kude uhlelo lwezifundo.

Mhlawumbe amahemuhemu zokungasebenzi kahle kwenziwe usosayensi esaphakama ngoba akazange ngokushesha wangena Ephakeme Polytechnic School of Zurich. Albert lolungenamaphutsa lidlule Luhlolo-physics kanye ne-mathematics, kodwa kwezinye eyala inani elidingekayo lamaphuzu kungukuthi kukora. Ukudonsa ku ulwazi oludingekile yezihloko, usosayensi esizayo ngempumelelo kudlule izivivinyo ngonyaka ozayo. Wayeneminyaka engu-17 ubudala.

Izinyoni On A Wire

Uke waphawula yini ukuthi izinyoni ngithande ukuhlala phezu izintambo? Kodwa kungani abafi ka ukushaqeka? Into wukuthi umzimba - hhayi umqhubi ezinhle kakhulu. Bird isidladla ukudala uxhumano okufanayo, ngokusebenzisa yiwo ogelezela a wamanje encane. Ugesi ukhetha wire okuyinto umqhubi kangcono. Kodwa kubalulekile ukuba uthinte inyoni ngaphezulu isici, ezifana ukwesekwa lusekelwe njengoba ugesi odlula esiswini sakhe, okwaholela ekufeni.

Kubhaklazeka ngokumelene izimoto

Amaqiniso ethakazelisayo physics angase akhumbule ngisho ngesikhathi ebuka idolobha izinhlanga, "Formula 1". Ezemidlalo izimoto lihamba ngesivinini phakathi underside imoto kanye ebusweni umgwaqo kudala ingcindezi ephansi, obekungadala ngokwanele ukukhulisa cover mgodi emoyeni. Yilokho okwenzeka komunye izinhlanga edolobheni. cover mgodi sibhekene umshini ezilandelayo, kwaqubuka umlilo, uhlanga sanqamuka. Kusukela ngaleso sikhathi, ukuze ugweme izingozi nesembozo mgodi basuke eziphothene kuya usebe.

amandla enuzi ngokuhlakaza Yemvelo

Omunye amagatsha ebaluleke kakhulu isayensi - Ikhalenda Elibukwa Kuqala. Amaqiniso ethakazelisayo Ulapha. Uthi bewazi nje ukuthi sekuyiminyaka eyizigidi eziyizinkulungwane ezingu emibili eyedlule, eziqhutshwa wangempela endaweni Oklo? Ukusabela eyalwiwa eminyakeni 100,000 phambi core uranium akuyona isiphelile.

Kuvele Eqinisweni ezithakazelisayo ukuthi ophendulayo wakwenza umqondo - e vein ye -uranium-ore yawela emanzini, okuyinto wadlala indima umengameli sezinzwa. Nge esebenzayo amanzi chain reaction ngesikhathi ngamathumba kude, futhi ukusabela iba buthakathaka.
