Amandla alondolozayo akulona igama lamandla, njengokudonsa phansi, ukungqubuzana, njll. Amandla alondolozayo achaza uhlobo lwamandla. Uma umsebenzi ophelele owenziwe amandla entweni, ngesikhathi into isuka endaweni yayo yokuqala kuze kube yilapho into ibuyela endaweni yayo yokuqala, ulingana no-zero, khona-ke amandla angamandla alondolozayo. Amandla abizwa ngokuthi alondolozayo uma umsebenzi owenziwe amandla entweni ungaxhomekile endleleni into eyithathayo kodwa kuphela ekushintsheni kwezikhundla zayo zokuqala nezokugcina.
Kungani umoya uzwakala upholile?
Kungani umoya upholile? Wake wabuza into efana nale.
Uma uzizwa ushisa kakhulu 😀 bese ngokuzumayo umoya opholile uvunguza, umzimba wakho uzizwa uqabulekile. Ngokuvamile, umoya uzizwa upholile. Mhlawumbe wake wazizwa umoya oshisayo? 😉 Umoya ungazizwa ushisa noma ubanda, kodwa umoya uvame ukuba pholile noma ubanda. Kungani umoya uzizwa upholile?
Umoya umoya ohamba ngenxa yokwehluka komfutho womoya . Umoya ungabangelwa nokuzungeza koMhlaba, kodwa lokhu akuxoxwa ngakho kulesi sihloko. Umoya uvame ukuhamba usuka ezindaweni ezinomfutho womoya ophezulu uye ezindaweni ezinomfutho womoya ophansi. Umfutho womoya uhlobene nobuningi bomoya noma isisindo sawo . Endaweni efanayo yokuphakama, umoya onomfutho ophezulu noma isisindo ucindezela kakhulu. Ngokuphambene nalokho, umoya onomfutho ophansi noma isisindo ucindezela kancane.
Ukushaja kukagesi
Izinto Zokushaja Zikagesi
Sicela ubheke enye yezinto ezikuzungezile. Uma ubhubhisa into, isibonelo idwala, idwala lizohlukana libe yizicucu eziningana ezincane. Uma idwala liphinda lichotshozwa, idwala lizophenduka libe yizicucu ezincane kakhulu. Kuthiwani uma izicucu zamadwala ziphinda zichotshozwa? Yiqiniso, izicucu zamadwala zichotshozwa futhi ziguqulwe zibe yizicucu ezincane kakhulu. Ingabe amatshe angahlukaniswa abe yizicucu ezincane kakhulu aze angabi namkhawulo? Iqiniso libonisa ukuthi noma iyiphi into uma ihlukaniswe yaba yizicucu ezincane izofika endaweni lapho ingxenye encane kakhulu yento ingeke ihlukaniswe ibe yizicucu ezincane. Ingxenye encane kakhulu yento engenakuhlukaniswa ibizwa ngokuthi i-athomu. Ngakho-ke i-athomu yingxenye encane kakhulu yazo zonke izinto endaweni yonke.
Imithetho kaNewton
Imithetho kaNewton yokunyakaza inezintathu, okungukuthi umthetho wokuqala kaNewton, umthetho wesibili kaNewton kanye nomthetho wesithathu kaNewton.
Umthetho Wokuqala KaNewton
UMthetho Wokuqala KaNewton uthi yonke into ephumule izohlala iphumule noma yonke into ehamba emgqeni oqondile ngesivinini esingaguquki izoqhubeka nokuhamba emgqeni oqondile ngesivinini esingaguquki uma amandla aphelele asebenza entweni engu-zero.
Amandla okungqubuzana
Ukungqubuzana kungamandla avimbela ukunyakaza kwento. La mandla asebenza phakathi kwezindawo ezixhumene. Kulesi sihloko, ukungqubuzana okufundwe kuhlobene namandla asebenza phakathi kwezindawo ezimbili eziqinile ezixhumene, njengokungqubuzana phakathi kwesisekelo sebhloko nephansi, ukungqubuzana phakathi kwesisekelo sesicathulo nephansi, noma ukungqubuzana phakathi kwesondo lemoto nomgwaqo.
Umfutho kanye Nomfutho
Umfutho oqondile
Umfutho oqondile noma ovame ukufushaniswa njengomfutho uchazwa njengomkhiqizo wobukhulu kanye nesivinini.
p = mv
Incazelo: p = umfutho, m = isisindo (ikhilogram), v = ijubane (imitha/isekhondi)
I-Momentum iyinani le-vector ngakho ngaphandle kokuba nobukhulu, i-momentum nayo inesiqondiso. Isiqondiso se-momentum sifana nesiqondiso sejubane lento noma isiqondiso sokunyakaza kwayo.
Umthetho wokulondolozwa kwamandla emishini
Ithiyori yamandla okusebenza-kinetic ithi umsebenzi ophelele, noma umzamo owenziwa amandla e-net entweni, ulingana noshintsho emandleni e-kinetic ento. Uma amandla e-net enza umsebenzi omuhle (amandla e-net asendleleni efanayo nokufuduka), khona-ke amandla e-kinetic ento ayanda. Ngokuphambene nalokho, uma amandla e-net enza umsebenzi ongemuhle (amandla e-net asendleleni ephambene nokufuduka), khona-ke amandla e-kinetic ento ayancipha.
Umzamo namandla
Uma ucindezela incwadi etafuleni ize ihambe, usuke wenza umsebenzi encwadini. Uma into iwela ebusweni bomhlaba ngoba idonswa ngamandla adonsela phansi, khona-ke amandla adonsela phansi ayasebenza entweni. Ngokuphambene nalokho, uma ucindezela into ngamandla akho onke uze ujuluke kodwa into ingahambi, khona-ke awukasebenzi entweni. Empilweni yansuku zonke, abanye abantu bathi usebenzile noma usebenze kanzima ukuze ucindezele into, kodwa ngokusho kwefiziksi , awukasebenzi entweni ngoba into ayihambi.
Ukunyakaza okujikelezayo okufanayo
Empilweni yethu yansuku zonke, sivame ukuhlangana nezinto ezihamba ngokujikeleza. Isibonelo esisodwa sento ehamba ngokujikeleza yisandla sesibili, isandla semizuzu, kanye nesandla sehora ewashini le-analog. Isandla sesibili sihlala sihamba nge-engeli engu-360 ° ngemizuzwana engu-60 (umzuzu owodwa) noma i-engeli engu-6 ° ngomzuzwana owodwa. Isandla semizuzu sihlala sihamba nge-engeli engu-360 ° ngemizuzu engu-60 (ihora elilodwa) noma i-engeli engu-6 ° ngomzuzu owodwa. Isandla sehora sihlala sihamba nge-engeli engu-360 ° emahoreni angu-24 (usuku olulodwa). Uma into ihamba ngokujikeleza njalo, njengesandla sesibili, isandla semizuzu, noma isandla sehora, kuthiwa lezi zinto zenza ukunyakaza okufanayo okujikelezayo . Ungasho isibonelo sokunyakaza okuvamile okujikelezayo okubonile noma okucabange ngakho?
Umthetho kaHooke
Uma welula ibhande lerabha noma ithayi lerabha kuze kufike endaweni ethile, lizonwebeka. Ngemva kokukhulula ukucindezeleka, irabha izobuyela ebude bayo bokuqala. Ngokufanayo, uma welula isipilingi, sizonwebeka. Ngemva kokuyikhulula, izobuyela ebude bayo bokuqala. Isipilingi noma irabha izonwebeka uma yeluliwe futhi izobuyela ebude bayo bokuqala ngemva kokukhululwa kokucindezeleka ngoba iyanwebeka. Ukunwebeka yikhono lento lokubuyela esimweni sayo sokuqala lapho amandla asetshenziswa kuyo esuswa.
