Ukusetshenziswa Kwamagagasi Omsakazo Kwezobuchwepheshe Amagagasi omsakazo ayingxenye ye-spectrum ye-electromagnetic enama-wavelength amade kanye nama-frequency aphansi kunokukhanya okubonakalayo, ama-X-ray, noma imisebe ye-gamma. Nakuba "engabonakali," amagagasi omsakazo akhona cishe kuzo zonke izici zokuphila kwanamuhla. Kusukela ekusakazweni komsakazo okulula kuya kumanethiwekhi eselula e-5G, kusukela ekuxhumaneni kwesathelayithi kuya... Funda kabanzi

Izibonelo Zezinkinga Emithethweni KaKirchhoff Imithetho kaKirchhoff iyisisekelo esibalulekile ekuhlaziyweni kwesekethe kagesi, ikakhulukazi lapho isekethe ingenakuxazululwa kusetshenziswa uMthetho ka-Ohm kuphela. Empilweni yangempela, isekethe kagesi ivame ukuba namagatsha amaningi, imithombo eminingana ye-voltage, kanye nama-resistor amaningana axhumene. Yilapho imithetho kaKirchhoff isisiza khona ukubala ugesi, i-voltage, kanye... Funda kabanzi

Isisekelo Sefiziksi Sezibalo Zesakhiwo Ukwakha izibalo zesakhiwo akuyona nje indaba "yokudweba amakholomu nemishayo" bese uwalinganisa ukuze azizwe ephephile. Ngemuva kwesinqumo ngasinye sokuklama—kusukela ebukhulu bemishayo, isikhala sekholomu, ubukhulu beslabhu yephansi, kuya emininingwaneni yokuxhuma—kunesisekelo sefiziksi esiyisisekelo esiqinisekisa amandla esakhiwo, ukuzinza, kanye nenduduzo. … Funda kabanzi

Incazelo Yefiziksi Yokuzamazama Komhlaba Ukuzamazama komhlaba kungenye yezinto zemvelo ezixoxwa kakhulu ngenxa yethonya lazo elibalulekile empilweni yabantu. Ngokombono wefiziksi, ukuzamazama komhlaba akugcini nje ngokuba "ukuzamazama komhlaba," kodwa kunalokho kuwumphumela wokukhishwa kwamandla okunwebeka aqongelelwe ngaphakathi kongqimba loMhlaba. Lesi sihloko sixoxa ngokuzamazama komhlaba ngolimi olulula... Funda kabanzi

I-Fenomena Yemvelo Echazwe yi-Fiziksi I-Fiziksi ivame ukubhekwa njengesihloko esigcwele amafomula kanye nezibalo, kodwa empeleni, isondelene kakhulu nokuphila kwansuku zonke. Cishe yonke into yemvelo esiyibukayo—kusukela ekuweni kwemvula kuya ekwakhekeni kothingo lwemvula kuya ekutheni kungani isibhakabhaka sibonakala siluhlaza okwesibhakabhaka—ingaqondwa ngemibono yemvelo. Ngokutadisha i-physics, asigcini nje ngekhanda imibono, kodwa futhi… Funda kabanzi

Imiphumela Yokushisa Kuma-Conductor Kagesi Imiphumela yokushisa ku-conductor kagesi yizinto ezifudumezayo ezenzeka lapho ugesi ugeleza ku-conductor. Empilweni yansuku zonke, lo mphumela ungaba wusizo—isibonelo, kuma-ayina kagesi, kuma-heater amanzi, kuma-soldering iron, nasezitovini zikagesi—kodwa futhi ungaba yingozi uma ungalawulwa, njengezintambo ezincibilikisayo, ama-short circuits, noma imililo ebangelwa ukufakwa kukagesi...

Iphepha Lefiziksi Ngamandla Avuselelekayo Isingeniso Amandla ayinani eliyisisekelo elibonakalayo empilweni yomuntu. Cishe yonke imisebenzi yesimanje—kusukela ekukhanyeni nasekuthuthweni kuya embonini nasekuxhumaneni—incike ekutholakaleni kwamandla ngendlela esebenzisekayo. Sekuyiminyaka engaphezu kwekhulu, izidingo zamandla emhlabeni wonke ziye zahlangatshezwa ngokuyinhloko ngamafutha asetshenziswayo njenge-oyili, amalahle, kanye negesi yemvelo… Funda kabanzi

Izimiso Zokusebenza Kwemoto Kagesi Imoto kagesi iyithuluzi eliguqula amandla kagesi abe amandla omshini ngendlela yokunyakaza okujikelezayo. Lobu buchwepheshe bakha umgogodla wamadivayisi ahlukahlukene esimanje, kusukela kumafeni namaphampu amanzi kuya emishinini yokukhiqiza efektri ngisho nezimoto zikagesi. Ukuqonda izimiso zokusebenza zama-motor kagesi kubalulekile hhayi kuphela kubafundi bobunjiniyela kodwa nakunoma ubani… Funda kabanzi

Izakhiwo ZikaMagnetic Zezinto Ezisetshenziswayo I-magnetism ingenye yezinto ezibonakalayo ezihlobene kakhulu nokuphila kwansuku zonke—kusukela kumakhampasi kanye nama-motor kagesi kuya kuzikhulumi namakhadi okugcina idatha. Ngemuva kwalezi zinhlelo zokusebenza ezisakazekile kukhona umqondo obalulekile obizwa ngokuthi izakhiwo zikamagnetic zezinto, okuyindlela izinto ezisabela ngayo ensimini yamagnetic. Le mpendulo iyahlukahluka ezintweni: ezinye… Funda kabanzi

Ubudlelwano Phakathi Kokucindezela Nokushisa Ukucindezeleka nokushisa kuyizinto ezimbili eziphathelene kakhulu ngokomzimba, ikakhulukazi uma kukhulunywa ngamagesi. Empilweni yansuku zonke, lobu buhlobo bungabonakala emathayini emoto, azizwa "enzima" ngemva kokusetshenziswa isikhathi eside, amathini e-aerosol, okungafanele afudunyezwe, ngisho naseziphekweni zokucindezela, ezisheshisa inqubo yokupheka. Nakuba kubonakala... Funda kabanzi
