Iinyani ezinika umdla malunga physics. Physics abasingqongileyo: anika umdla

Yintoni isayensi zizityebi zibakala umdla na? Physics! Grade 7 - lixesha xa abafundi beqala ukufunda kuyo. Ukuba akazange ibonakala kakhulu mba isicefe kunjalo, simele sinikele ukuqalisa ukufunda fun izibakala.

Kutheni imibala yomnyama ezisixhenxe

iinyani ezinika umdla malunga physics ngayo inokude ichukumise umnyama! Inani imibala kulo echazwe Isaak Nyuton. Lo mkhuba umnyama, banomdla kakhulu Aristotle, kunye umphengululi umongo Persian Wavuleka emva kwinkulungwane 13-14. Sekunjalo, ijikwa inkcazelo yomnyama obakhoyo efini, ukuba Newton wakwenzayo "Optics 'yakhe 1704. Wayifanisa umbala usebenzisa bemilo yeglasi.

Ukuba ujonga ngeliso e umnyama, ungabona indlela imibala flow kakuhle zibe omnye komnye, kusenziwa inani elikhulu imibala. Kwaye Newton ekuqaleni zabelwe ezingundoqo ezintlanu kuphela: ezibomvu, bhlowu, eluhlaza, otyheli, obomvu. Kodwa ke sisazinzulu ukuba amkhanuke yamanani, ngoko ke wayefuna ukuba zazise inani imibala inani eyimfihlakalo "asixhenxe". Wongeza ukuba inkcazo yomnyama kusekho imibala ezimbini --orenji kunye oluhlaza. Ngoko ukufumana umnyama ezisixhenxe elimbala.

ingamanzi

Physics - abasingqongileyo. olunika umdla Basenokothuka kuthi, nokuba xa kuziwa kwizinto eziqhelekileyo ezifana namanzi zesiqhelo. Thina sonke baqhele ukucinga ukuba kulwelo akanayo imilo, ithi nokuba incwadi yesikolo physics! Noko ke, akunjalo. ifomu ulwelo Natural - ibhola.

Ukuphakama Eiffel Tower

Yintoni na ubude ngqo Eiffel Tower? Kwaye oko kuxhomekeke kwimozulu! Isibakala sokuba le indawo ephakamileyo, ende yahluka nge-12 cm. Oku kuvela kwinyaniso yokuba xa imozulu eshushu, isakhiwo solar eshushu, kwaye iqondo ngemiqadi besukelana 40 degrees Celsius. Kwaye njengoko yaziwa, izinto ekwayiyo phantsi lobushushu eliphezulu.

zesayensi abazinikeleyo

iinyani ezinika umdla malunga yemvelo ayikwazi kuphela kuba mnandi, kodwa ukuthetha ngokuzinikezela kwabo nokuzinikela umsebenzi yakhe ayithandayo. Ngexesha ukufunda sombane arc yamachiza Vasily Petrov wazisusa umaleko ongaphezulu wesikhumba zeminwe ukuba kwemisinga buthathaka.

Kwaye Isaak Nyuton yaziswa emehlweni ayo probe ukuqonda uhlobo umbono. Izazinzulu zikholelwa ukuba sibona kuba uxinzelelo ukukhanya kwi retina.

entlabathini

iinyani ezinika umdla malunga physics kunceda ukuqonda iimpawu zezinto yokonwabisa ezinjalo ezifana entlabathini. Yokuba fluid non-Newtonian. Umntu okanye isilwanyana ukuntywila kungena ozika ngenxa ngokupheleleyo ukuya viscosity eziphakamileyo, kodwa uphume kunzima kakhulu. Ukuze ufumane unyawo lwakho ngaphandle ozika, kufuneka wenze umgudu ezinokuthelekiswa kunye ngokuvuswa emotweni.

Akwenzeki ukuba sifele, kodwa ingozi ebomini na emzimbeni, ilanga, tide. Xa lesitofu ozika kufuneka ndilale umva ulinde uncedo.

isantya hypersonic

Uyazi, yayiyintoni na isixhobo kuqala ukuba ndimaphule umqobo isandi? Umbhexeshi umalusi Ordinary ngayo. Nqakraza iinkomo eloyikekayo, akukho nto ifana yomqhaphu ekuqubisaneni isantya isandi! It ungqubeka esithinzini lihamba isabhokhwe ngokukhawuleza ukuba kudala okubulala emoyeni. Into efanayo-moya sibhabhe ngesantya supersonic.

photon sphere

iinyani ezinika umdla malunga yemvelo kunye nohlobo mingxuma abamnyama abanjalo ukuba ngamanye amaxesha kunzima ukucinga nokuba abuphumezayo izibalo theory. Yinto eyaziwayo ukuba ukukhanya luqulathe ziluhlaza. Ewela phantsi kweempembelelo womxhuzulane ukwenza black umngxuma ziluhlaza arc, indawo apho aqalise ukujikeleza. Oosonzululwazi bakholelwa ukuba xa ubeke umntu sphere photon, uyabona umva wakhe.

scotch

Akuthandeki ukuba unwound tape emoyeni, kodwa abaphandi kwilebhu wakhe. Kwaye ke ndafumanisa ukuba kukho imitha abonakale-X-reyi ngexesha imicu. amandla X-ray kangangokuba ikuvumela ukuba uthathe imifanekiso yamalungu omzimba! Kwaye loo nto oku kuyenzeka - ingaziwa. A nomphumela ofanayo ibonakala ekutshatyalalisweni Iimbophelelo yezi kwi njengekristale. Kodwa ke into - akukho isakhiwo crystal kwi enamathelayo ayinayo. Ngoko ke oosonzululwazi baye kunye nenye ingcaciso. Ngaba ukoyika naziphi i tape kwi khaya - emoyeni, akukho radiation kwenzeka.

Ucwaningo abantu

Ngowe-1746, yamachiza waseFrance, ngaxeshanye, Jean-Antuan Nolle umbingeleli kuphandwe uhlobo yangoku yombane. Le Isazinzulu isigqibo ukufumanisa ukuba yintoni na isantya umsinga wombane. Nantso kwenziwa nje njani eMonastri ...

Yemvelo wamenywa ukuba kunjani 200 neemonki kubo ngocingo zentsimbi kunye nokugxothwa ebhetri wretches ze iingqayi abasandula yasungulwa Leyden (ukuba ezi capacitors kuqala). Zonke ithe basabela yogwayimbo ngexesha elinye, kwaye oku kuye wakwenza kwacaca ukuba isantya sokuqukuqela liphezulu kakhulu.

iyivume ngokuhlakanipha

olunika umdla nobomi zesayensi Ungathumela bobuxoki nethemba dunce. legend ehamba phakathi abafundi yokungakhathali ukuba Einstein yodumo luphumelele lenene, wayengazi ukuba imathematika bonke flunked iimviwo zokugqibela. Kwaye akukho nto, waba emhlabeni nzulu esidumileyo. Siza kukhawuleza ukudanisa: Albert Einstein waqala ukubonisa ubuchule elimangalisayo zezibalo njengomntwana yaye ulwazi, kude ngokukhawulezisa ikharityhulam.

Mhlawumbi amarhe zokusebenza kwizisweli sisazinzulu kwavela kuba akazange ngoko nangoko wangena Higher Polytechnic School of Zurich. Albert ngobuciko abapase iimviwo physics nemathematika, kodwa kwezinye iinkalo efunekayo Inani lamanqaku nje amanqaku. Iphakama phezu nolwazi oluyimfuneko kwezi zifundo, lo nzulu elizayo zigqithile ngempumelelo iimviwo kunyaka olandelayo. Wayeneminyaka eli-17 ubudala.

Iintaka On A Wire

Ngaba wakha waphawula ukuba iintaka Ungathanda ukuhlala phezu ngcingo? Kodwa kutheni kufa yokothuka? Eyona nto kukuba umzimba - hayi umqhubi elungileyo kakhulu. Bird paw ukudala uqhagamshelwano parallel, ujikeleze lonke apho current encinane. Umbane ithanda ucingo leyo umqhubi engcono. Kodwa ke kuyimfuneko ukuba bachukumise intaka ngaphezulu i element, ezifana inkxaso inculwe nombane nemikhanzi esiswini sakhe, nisingise ekufeni.

Izivingco nxamnye ezimotweni

iinyani ezinika umdla malunga physics unako ukukhumbula ngoxa ebukele imidyarho isixeko, "Formula 1". iimoto Sports ezihamba kwi ngesantya esiphezulu phakathi elingaphantsi emotweni kunye endleleni kudala umfutho, leyo kuba ngokwaneleyo ukuze uphakamise isiciko emiseleni i emoyeni. Yiloo nto kanye eyenzeka omnye iintlanga umzi. Emiseleni cover senze umatshini ilandelayo, kwavuka umlilo, ugqatso samiswa. Ukususela ngoko, ukuze uphephe iingozi izingxobo emiseleni ofunwa ukuba undi.

reactor yenyukliya Natural

Enye amasebe ezibalulekileyo kwinzululwazi - physics yenyukliya. olunika umdla apha. Ngaba uyazi ukuba kwiminyaka billion emibini eyadlulayo, savula indawo Oklo wokwenene? Indlela abasabela kwenzeka iminyaka 100,000 phambi core uranium lo akakhange azisebenzise.

An into umdla kukuba reactor lendlela ndo - xa umthambo ka uranium ekrwada yeyela emanzini, nto leyo wadlala indima umongameli zemithambo-luvo. Ngamanzi chain reaction esebenzayo ngexesha ithumba kude, kwaye indlela liyafa.
