Wake wayibuka indiza ihamba endaweni yokuma kwendiza? Uma kungenjalo, zinike isikhathi sokuvakashela isikhumulo sezindiza edolobheni lakini. Bheka ukunyakaza kwendiza njengoba isuka noma ihlala. Lapho isuka, indiza iqala ukuhamba iqonde endaweni yokuphumula, bese ishesha ize ihambe ekugcineni. Ngokuphambene nalokho, lapho ifika, ukunyakaza kwendiza, okwakushesha kakhulu ekuqaleni, kuyehla kancane kancane. Ukunyakaza kwendiza endaweni yokuma kwendiza kuyisibonelo salokhu. ukunyakaza okuqondile okusheshisiwe ngokulinganayo Ngasohlangothini oluvundlile. Wake wasibona isithelo esiwile esiqwini saso sawela phansi? Ukunyakaza kwesithelo noma into ewela phansi isuka ekuphakameni okuthile kuyisibonelo sokunyakaza okuqondile okusheshiswa ngokulinganayo ohlangothini oluqondile, futhi lokhu kuxoxwa ngakho ngokuningiliziwe ku ukunyakaza kokuwa kwamahhalaUnganikeza izibonelo zokunyakaza okuqondile okusheshiswa ngokulinganayo empilweni yansuku zonke?
Ifiziksi Yesikole Samabanga Aphezulu
Izihloko zefiziksi mayelana nezenzakalo zemvelo njll. ezihlobene nefiziksi.
Ukunyakaza okuqondile okufanayo
Wake wagibela noma wagibela isithuthuthu noma imoto? Ngethemba ukuthi akunjalo 🙂 hehe… uhlala ehlathini 😀 Uma isithuthuthu noma imoto eshayelwayo ihamba ngendlela eqondile futhi ijubane layo lingaguquki, isibonelo amakhilomitha angu-60 ngehora khona-ke isithuthuthu noma imoto ihamba ngendlela eqondile ngesivinini esingaguquki (i-GLB). Imikhumbi ehamba ngesikebhe noma izindiza nazo ngezinye izikhathi zenza i-GLB. Kulula ukubona izinto zihamba ngendlela eqondile empilweni yansuku zonke kodwa kunzima ukubona izinto zenza i-GLB. Ungasho isibonelo se-GLB oye wayibona noma wayicabanga?
Ukwengezwa kwevektha
Ukwengezwa kwevektha kungenziwa ngemidwebo (kusetshenziswa izithombe) nangokuhlaziya (kusetshenziswa izibalo).
Ukwengezwa kwevektha yezithombe
Ukwengezwa kwevektha yezithombe kungukwengezwa kwevektha okwenziwa ngokudweba amavektha azongezwa kanye nevektha ephumelayo, bese ubukhulu bevektha ephumelayo butholakala ngokulinganisa kusetshenziswa irula.
Ukunyakaza okujikelezayo
Impilo yethu namuhla isibe lula futhi ikhululekile ngokuba khona kwezimoto ezinamasondo, imishini yesimanje efana namajeneretha, imishini yokugaya, amafeni, imishini yokugunda utshani, imishini yokufafaza izimbali njalo njalo. Izimoto ezinamasondo ezifana namabhayisikili, izithuthuthu, izimoto nezindiza azikwazi ukuhamba uma zingenawo amasondo noma uma amasondo engajikelezi. Izindiza ezinophephela emhlane noma izindiza nazo azikwazi ukundiza uma ama-propeller azo engajikelezi. Imikhumbi ayikwazi ukuhamba uma amajeneretha noma ama-propeller azo engajikelezi. Ebusuku, indlu iba mnyama kakhulu futhi akukho ukuzijabulisa uma ijeneretha noma isitshalo sikagesi singasebenzi. Izinto eziningi zenza ukunyakaza okujikelezayo nsuku zonke. Ngisho noma singaqapheli, umhlaba esiphila kuwo, inyanga esikhanyisa ebusuku, amasathelayithi okwenziwa njengamasathelayithi okuxhumana adlulisela amaza kagesi kumabonakude, umsakazo, omakhalekhukhwini, kanye nokusakazwa kwe-inthanethi, ayajikeleza futhi ahlala ejikeleza, okubizwa nangokuthi ahamba ngendilinga ngaso sonke isikhathi.
Ukunyakaza okuqondile
Izinto Zokunyakaza Okuqondile
Ukunyakaza kuyinto esiyiqaphela njalo empilweni yansuku zonke. Igatsha lefiziksi elifunda ukunyakaza libizwa ngokuthi ama-mechanics. Igatsha lama-mechanics elixoxa ngendlela into ehamba ngayo, ngaphandle kokucabangela imbangela yokunyakaza, libizwa ngokuthi amandla e-kinetic. i-kinematicsNgokuphambene nalokho, igatsha lemishini elifunda izimbangela zokunyakaza kwezinto futhi lichaze ukuthi kungani izinto zihamba njengoba zenza yi-dynamics. Kulesi sihloko, yonke into ehambayo ibhekwa njengokungathi iyinhlayiya noma iphuzu (.). Izinto ezihambayo zibhekwa njengamaphuzu ukuze kube lula ukuhlaziya kwethu. Cabanga uma iphuzu lihamba emgqeni oqondile, khona-ke umkhondo walo uzokwakha umugqa oqondile.
Ukunyakaza kwamahhala kokuwa
Izinto Zokunyakaza Kwamahhala Zokuwa
Esikhathini esedlule, ukunyakaza kwezinto eziwayo Ukuwa phansi kuyisihloko esithakazelisayo kakhulu kwifilosofi yemvelo. Isazi sefilosofi u-Aristotle wake wathi izinto ezinobunzima obukhulu ziwela ngokushesha kunezinto ezilula. Umbono ka-Aristotle wathonya imibono yabantu abaphila ngaphambi kukaGalileo, ababekholelwa ukuthi izinto ezinobunzima obukhulu ziwela ngokushesha kunezinto ezilula nokuthi izinga lokuwa kwento lilingana nobunzima bayo. Mhlawumbe ngaphambi kokufunda lesi sihloko, nawe wacabanga into efanayo.
Ukunyakaza kwe-parabolic
Ukunyakaza kwe-parabolic noma ukunyakaza okuqoshwe phansi uhlobo lokunyakaza lapho into inikezwa khona ijubane lokuqala bese ukunyakaza kwento kuthonywa ngokuphelele amandla adonsela phansi. Ukunyakaza okuqoshwe phansi phansi kuwukunyakaza okunezinhlangothi ezimbili, inhlanganisela yokunyakaza eziqondisweni ezivundlile neziqondile, ngokungafani ukunyakaza okuqondile noma ukunyakaza kokuwa kwamahhala okuwukunyakaza okunobukhulu obubodwa.
UGalileo wachaza ukuthi ukunyakaza okufana nokwe-parabolic kungaqondwa ngokucabangela izingxenye eziqondile nezivundlile zokunyakaza ngokwehlukana. Ukusheshisa kwamandla adonsela phansi kusebenza kuphela ohlangothini oluqondile; akwenzi ohlangothini oluqondile. Ngakho-ke, ingxenye evundlile yokunyakaza okubonakalayo ibhekwa kanje: ukunyakaza okuqondile okufanayo futhi ingxenye eqondile yokunyakaza okufana nokwe-parabolic ibhekwa njengokunyakaza kokuwa okukhululekile.
Umthetho kaNewton wamandla adonsela phansi
Umthetho kaNewton Wezinto Ezidonsela Phansi
Kungani izithelo ziwela noma ziqhubekela ebusweni bomhlaba ngemva kokukhululwa esiqwini sazo? Imithetho kaNewton ithi uma isithelo sinyakaza, kumele kube namandla asebenzayo kuso. Amandla abangela ukuba into iwele ngokukhululeka ebusweni boMhlaba abizwa ngokuthi amandla adonsela phansi oMhlaba.
Inkinga yezinto eziwayo ezihilela amandla adonsela phansi, oyifundayo manje, yaqala ukucatshangelwa futhi yafundwa ngusosayensi waseBrithani ongasekho u-Isaac Newton. Ukukhathazeka kukaNewton kuvela eGrisi lasendulo. Kunezinkinga ezimbili eziyisisekelo amaGreki ayezihlola kudala ngaphambi kokuba uNewton azalwe.
Ubukhulu namayunithi
Ubuningi kanye nezinto zokwakha
Ubuningi obuphathekayo Inani yinoma yini engalinganiswa ngokuqondile noma ngokungaqondile, futhi imiphumela yokulinganisa ivezwa ngezinombolo namayunithi. Ukuphakama nobunzima kuyizibonelo zobuningi obuphathekayo obungalinganiswa ngqo. Isibonelo sobuningi obuphathekayo obungalinganiswa ngokungaqondile yivolumu. Uma ufuna ukuthola umthamo webhavu lokugeza endlini yakho yokugezela, qala ulinganise ubude, ububanzi, kanye nokuphakama kwebhavu usebenzisa i-tape measure noma i-ruler. Bese, phinda ubude, ububanzi, kanye nokuphakama ukuze uthole umthamo webhavu lokugeza.
