Wake wayibona indiza ihamba endaweni yokugijima? Uma kungenjalo, zinike isikhathi sokuya esikhumulweni sezindiza edolobheni lakini. Qaphela ukunyakaza kwendiza lapho isizosuka noma isizofika. Lapho isizosuka, indiza iqala ukuhamba iqonde isuka esimweni sokuma bese ukunyakaza kwayo kushesha kuze kube yilapho indiza ekugcineni indiza. Ngokuphambene nalokho, lapho ifika, ukunyakaza kwendiza, okwakushesha kakhulu ekuqaleni, kuyehla kancane kancane. Ukunyakaza kwendiza endaweni yokugijima kuyisibonelo sokunyakaza okuqondile okushesha ngokulinganayo ohlangothini oluvundlile. Wake wayibona isithelo esiwile esiqwini saso sawela phansi? Ukunyakaza kwesithelo noma into ewela phansi isuka ekuphakameni okuthile kuyisibonelo sokunyakaza okuqondile okusheshisiwe ngokulinganayo ohlangothini oluqondile futhi lokhu kuxoxwa ngakho ngokuningiliziwe ekwindla yamahhala . Unganikeza izibonelo zokunyakaza okuqondile okusheshisiwe okufanayo 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 esiyiqaphelayo njalo empilweni yansuku zonke. Igatsha le-physics elifunda ukunyakaza libizwa ngokuthi ama-mechanics. Igatsha lama-mechanics elixoxa ngendlela into ehamba ngayo, ngaphandle kokucabangela imbangela yokunyakaza, libizwa ngokuthi i-kinematics . Ngokuphambene nalokho, igatsha lama-mechanics elixoxa ngezimbangela zokunyakaza futhi lichaze ukuthi kungani izinto zihamba njengoba zenza libizwa ngokuthi ama-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
Ezikhathini zasendulo, ukunyakaza kwezinto eziwela phansi kwakuyisihloko 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 ijubane lokuwa kwento lihambisana nobunzima bayo. Mhlawumbe ngaphambi kokufunda lesi sihloko, nawe wacabanga into efanayo.
Ukunyakaza kwe-parabolic
Ukunyakaza kwe-parabolic noma ukunyakaza kwe-projectile uhlobo lokunyakaza lapho into inikezwa khona ijubane lokuqala bese ukunyakaza kwayo kuthonywa ngokuphelele amandla adonsela phansi. Ukunyakaza kwe-projectile kuwukunyakaza okunezinhlangothi ezimbili, inhlanganisela yokunyakaza okuvundlile nokuqondile, ngokungafani nokunyakaza okuqondile noma ukuwa okukhululekile, okuwukunyakaza okunezinhlangothi eyodwa.
UGalileo wachaza ukuthi ukunyakaza kwe-parabolic kungaqondwa ngokucabangela izingxenye eziqondile nezivundlile zokunyakaza ngokwehlukana. Ukusheshisa kwamandla adonsela phansi kusebenza kuphela ohlangothini oluqondile, hhayi ohlangothini oluvundlile. Ngakho-ke, ingxenye evundlile yokunyakaza kwe-projectile ibhekwa njengokunyakaza okuqondile okufanayo , kanti ingxenye evundlile yokunyakaza kwe-parabolic ibhekwa njengokuwa okukhululekile.
Umthetho kaNewton wamandla adonsela phansi
Umthetho kaNewton Wezinto Ezidonsela Phansi
Kungani isithelo siwela noma sihamba siye ebusweni boMhlaba ngemva kokususwa esiqwini saso? Imithetho kaNewton ithi uma isithelo sihamba, 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
Inani elibonakalayo yinoma yini engalinganiswa ngokuqondile noma ngokungaqondile, futhi imiphumela ivezwa ngezinombolo namayunithi. Ukuphakama nobunzima kuyizibonelo zobuningi obubonakalayo obungalinganiswa ngqo. Isibonelo sobuningi obubonakalayo 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.
