Iphepha Lefiziksi Ngemithetho KaNewton Isingeniso Ifiziksi iyigatsha lesayensi yemvelo elifunda izenzakalo nokuziphatha kwendawo yonke ngokubuka, ukulinganisa, kanye nokwakhiwa kwemithetho esebenzayo ngokuvamile. Esinye sezisekelo eziyinhloko zefiziksi yakudala yiMithetho KaNewton Yokunyakaza. Le mithetho yasungulwa nguSir Isaac Newton ngekhulu le-17 futhi isebenza njengesisekelo sokuqonda… Funda kabanzi
Umthetho Oyisisekelo Wokulingana Kwemishini Ukulingana kwemishini yisimo lapho into ingashintshi khona ukunyakaza kwayo konke: akukho ukusheshisa kokuhumusha (ukuhamba emgqeni oqondile) kanye nokusheshisa kokujikeleza (ukujikeleza). Lo mqondo uyisisekelo esibalulekile ku-physics yobunjiniyela, ikakhulukazi ku-statics, structural mechanics, mechanics, kanye nobunjiniyela bezakhiwo. Ukuqonda ukuthi kungani ibhuloho lingahlala liqinile… Funda kabanzi
Ukusetshenziswa kweFiziksi kwiSayensi ye-Forensic Isayensi ye-forensic iwumkhakha ohlanganisa isayensi nomthetho ukuze wembule amaqiniso ngemuva kwesehlakalo, ikakhulukazi ubugebengu. Phakathi kwamagatsha ahlukahlukene esayensi adlala indima ebalulekile, i-physics iphethe isikhundla esibalulekile ngoba inikeza uhlaka lokulinganisa, ukwenza amamodeli, kanye nokwakha kabusha imicimbi ngobuqotho. Kusukela ekuhlaziyweni kwephethini le-bloodstain kuya ekwakhiweni kabusha… Funda kabanzi
Indlela Yokubala Ukucindezeleka Kwegesi Ukucindezeleka kwegesi kuwumqondo obalulekile ku-physics nakumakhemikhali ovame ukuvela empilweni yansuku zonke—kusukela emathayini ezimoto kanye namasilinda e-LPG kuya kuma-aerosol kanye nezinqubo zelebhu. Ukuqonda ukuthi singabala kanjani ukucindezeleka kwegesi kusisiza ukubikezela ukuziphatha kwegesi njengoba ivolumu yayo ishintsha, njengoba izinga lokushisa layo lishintshashintsha, noma njengoba inani layo likhuphuka. Lesi sihloko… Funda kabanzi
Izisekelo Zefiziksi Zokukhanya Ukukhanya kungenye yezinto zemvelo ezihlobene kakhulu nokuphila komuntu. Sidinga ukukubona, ukusebenzise kwezobuchwepheshe (kusukela kumakhamera kuya kuma-fiber optics), futhi sikufunde ukuze siqonde isakhiwo esiyisisekelo sendawo yonke. Kufiziksi, ukukhanya kubhekwa njengohlobo lwamandla olungasakazeka, lusebenzisane nezinto, futhi lubonise izakhiwo ngezinye izikhathi... Funda kabanzi
Ukuqonda Nokwakha I-Impulse I-Impulse ingumqondo obalulekile ku-physics, ikakhulukazi ocwaningweni lwe-mechanics, olubhekene nokunyakaza kwezinto namandla. Lo mqondo uvame ukuvela lapho kuxoxwa ngokushayisana, njengokushaywa kwebhola, ukushayisana kwemoto, noma umsubathi ebamba ibhola. Nakuba lezi zenzakalo zimfushane, imiphumela yazo ingaba nkulu ngoba ihilela izinguquko ku... Funda kabanzi
Ithiyori Yamandla Avuselelekayo Amandla avuselelekayo angenye yezihloko ezibaluleke kakhulu ezingxoxweni zentuthuko esimeme. Phakathi kokwanda kwesidingo samandla omhlaba wonke, inkinga yesimo sezulu, kanye nezinsizakusebenza zamafutha ezincishisiwe, amandla avuselelekayo aziveza njengendlela engcono kakhulu enobungani nemvelo futhi engase ibe ngcono esikhathini eside. Kodwa-ke, ukuze siqonde ngokugcwele amandla avuselelekayo, sidinga ukubukeza "ithiyori" yawo: … Funda kabanzi
Ukusetshenziswa kweFiziksi kubuchwepheshe bokuxhumana Ubuchwepheshe bokuxhumana bungenye yezimpumelelo ezibaluleke kakhulu zempucuko yanamuhla. Kusukela kumaselula, umsakazo, ithelevishini, kuya ku-inthanethi esheshayo, konke kuvumela abantu ukuthi bashintshisane ngolwazi ngokushesha ngaphandle kwemingcele yebanga. Ngemuva kwalokhu kulula kukhona indima ebalulekile yefiziksi, enikeza isisekelo sesayensi sendlela amasignali akhiqizwa ngayo, adluliselwa ngayo, akhuliswe ngayo, futhi amukelwe ngayo. … Funda kabanzi
Indlela Yokubala Amandla E-Kinetic Amandla ngumqondo obalulekile ku-physics ochaza ikhono lento lokwenza umsebenzi. Empilweni yansuku zonke, sivame ukuhlangana namandla ngezindlela ezahlukene—kusukela emandleni okushisa kuya emandleni kagesi kuya emandleni e-kinetic. Enye yezinhlobo zamandla ezilula ukuzibona amandla e-kinetic, okungamandla into enawo ngenxa yokunyakaza kwayo. Funda kabanzi
I-Fiziksi kwiSayensi Yezemvelo Isayensi yezemvelo ivame ukuqondwa njengomkhakha ohlobene kakhulu ne-biology, i-chemistry, noma inqubomgomo yomphakathi. Kodwa-ke, isisekelo esisodwa esibalulekile sivame ukunganakwa: i-physics. I-Fiziksi akuyona nje inkolelo-mbono yamandla nokunyakaza, kodwa kunalokho iyithuluzi lokuqonda ukuthi amandla ageleza kanjani, ukuthi izinto zihamba kanjani, nokuthi izinhlelo zemvelo zisabela kanjani ekuphazamisekeni. Lapho… Funda kabanzi
