Injini yeCarnot ingenye yemiqondo eyisisekelo kakhulu ku-thermodynamics futhi idonsele ukunaka kososayensi kusukela ngekhulu le-19. Yasungulwa ngunjiniyela waseFrance uSadi Carnot, ibhekwa njengemodeli efanelekile yokuqonda ukusebenza kahle okuphezulu okungatholakala yinjini yokushisa. Lesi sihloko sizoxoxa ngokujulile ngesimiso sokusebenza senjini yeCarnot, inkolelo-mbono yayo, kanye nokusetshenziswa kwayo.
Indlela Yokubala Umsebenzi Namandla Izibalo kanye nefiziksi ngokuvamile kungabonakala kusabisa kwabaningi, kodwa uma sesiqonda imiqondo eyisisekelo ngemuva kokubala kanye nokusetshenziswa kwazo okusebenzayo, lezi zinsimu ezimbili zingaba mnandi kakhulu. Imiqondo emibili ebalulekile evame ukuhlotshaniswa nefiziksi umsebenzi kanye namandla. Lesi sihloko sizoxoxa ngendlela yokubala umsebenzi… Funda kabanzi
Umphumela Wamandla Adonsela Phansi Esikhathini Amandla adonsela phansi nesikhathi yimibono emibili eyisisekelo eye yaheha ososayensi nezazi zefilosofi amakhulu eminyaka. Ngendlela yayo elula, amandla adonsela phansi afihla ngemuva kwemfihlakalo yokusebenzisana phakathi kwenqwaba enkulu endaweni yonke, kuyilapho isikhathi sivame ukubhekwa njengokugeleza okuqhubekayo kusukela esikhathini esidlule kuya esikhathini samanje futhi ekugcineni kube… Funda kabanzi
Indlela Yokusebenza Kokukhanya Kwe-Photoelectric Umphumela we-photoelectric uyinto eyenzeka ku-physics ehilela ukukhishwa kwama-electron ebusweni bento lapho ukukhanya noma imisebe ye-electromagnetic ishaya khona. Lo mphumela wabonwa okokuqala ngusosayensi waseJalimane uHeinrich Hertz ngo-1887 futhi kamuva wachazwa ngokuningiliziwe ngu-Albert Einstein ngo-1905, okwagcina kumtholele uMklomelo KaNobel ku-Physics ngo-1905.
Ukusetshenziswa Kwamaza Omsindo Kwezobuchwepheshe Ezweni lobuchwepheshe besimanje, amaza omsindo anezinhlelo zokusebenza ezibanzi kakhulu nezibalulekile. Amaza omsindo, okuyizinto ezishukumisa umoya noma ezinye izindlela, angasetshenziswa ngezinhloso ezahlukahlukene, kusukela ekuxhumaneni kuya kwezokwelapha. Lesi sihloko sizobuyekeza ezinye zezinhlelo zokusebenza eziyinhloko zamaza omsindo kwezobuchwepheshe, okuhlanganisa ukuxhumana ngocingo, i-sonar, i-ultrasound, kanye… Funda kabanzi
Ukungqubuzana Okungaguquki Nokujikijela Okujikijela kungenye yamandla avame kakhulu kodwa avame ukunganakwa empilweni yansuku zonke. Izinhlobo ezimbili eziyinhloko zokungqubuzana esivame ukubhekana nazo ukungqubuzana okungaguquki kanye nokungqubuzana okujikijela. Zombili izinhlobo zokungqubuzana zidlala indima ebalulekile ezicini ezahlukene zokuphila, kusukela ekuhambeni ngezinyawo kuya ekushayeleni… Funda kabanzi
Imibuzo Nezingxoxo Ze-Rotational Dynamics I-Rotational dynamics iyisihloko esibalulekile ku-physics esixoxa ngokunyakaza kwezinto ezijikelezayo. Lesi simo sihlanganisa imiqondo eminingi, njenge-moment of inertia, i-torque, umthetho wesibili kaNewton wokujikeleza, amandla e-rotational kinetic, neminye. Lesi sihloko sizokwethula izinkinga eziningana kanye nezingxoxo mayelana ne-rotational dynamics ukuze kucaciswe ukuqonda kwale miqondo... Funda kabanzi
Ukuchazwa Komthetho KaFaraday Wokusebenzisa Ugesi Kagesi UMichael Faraday wayengomunye wososayensi abanethonya elikhulu emlandweni wesayensi. Ngochungechunge lwezilingo zokudala kanye nomdlandla ongakhathali, wathola imiqondo eyaba yisisekelo sokusetshenziswa kogesi kagesi kwanamuhla. Omunye weminikelo yakhe emikhulu kwaba uMthetho KaFaraday Wokusebenzisa Ugesi Kagesi Kagesi, owachazwa okokuqala ngo-1831. Lo mthetho uchaza… Funda kabanzi
Ama-calorimeter ayithuluzi elibalulekile kumakhemikhali naku-physics, asetshenziselwa ukukala inani lokushisa elihilelekile ezinqubweni zomzimba nezamakhemikhali. Besebenzisa ama-calorimeter, ososayensi banganquma izinguquko zamandla ezihilelekile ekusabeleni kwamakhemikhali, izinguquko zesigaba, kanye nezinye izinqubo. Kulesi sihloko, sizohlola izici ezahlukahlukene zokusebenzisa ama-calorimeter… Funda kabanzi
Ucwaningo Lwecala Lomthetho Ka-Archimedes: Ukwembula Imfihlakalo Yomqhele Wegolide Isingeniso Umthetho ka-Archimedes, owaziwa nangokuthi isimiso sika-Archimedes, ungomunye wemithetho eyisisekelo kakhulu ku-physics nobunjiniyela. Owatholwa yisazi sezibalo nesazi sefiziksi sasendulo samaGreki u-Archimedes cishe ngo-250 BC, uthi noma iyiphi into ecwila noma entanta oketshezini izothola… Funda kabanzi
