Mphamvu yosunga zinthu mwadongosolo si dzina la mphamvu, monga mphamvu yokoka, kukangana, ndi zina zotero. Mphamvu yosunga zinthu mwadongosolo imafotokoza mtundu wa mphamvu. Ngati ntchito yonse yochitidwa ndi mphamvu pa chinthu, panthawi yomwe chinthucho chikuchoka pamalo ake oyambirira mpaka chinthucho chibwerere pamalo ake oyambirira, ndi yofanana ndi zero, ndiye kuti mphamvuyo ndi mphamvu yosunga zinthu mwadongosolo. Mphamvu imatchedwa yosunga zinthu mwadongosolo ngati ntchito yochitidwa ndi mphamvu pa chinthu sichidalira njira yomwe chinthucho chimatenga koma kungodalira kusintha kwa malo ake oyamba ndi omaliza.
N’chifukwa chiyani mphepo imamveka bwino?
N’chifukwa chiyani mphepo imamveka bwino? Kodi munayamba mwafunsapo funso ngati ili?
Ngati mukumva kutentha kwambiri 😀 ndipo mwadzidzidzi mphepo yamphamvu ikuwomba, thupi lanu limamva kutsitsimuka. Nthawi zambiri, mphepo imamva kuzizira. Mwina munamvapo mphepo yamphamvu yomwe imamva kutentha? 😉 Mpweya ukhoza kumva kutentha kapena kuzizira, koma mphepo nthawi zambiri imakhala yozizira kapena yozizira. N’chifukwa chiyani mphepo imamva kuzizira?
Mphepo ndi mpweya womwe umayenda chifukwa cha kusiyana kwa kuthamanga kwa mpweya . Mphepo imathanso kuchitika chifukwa cha kuzungulira kwa Dziko Lapansi, koma izi sizikufotokozedwa m'nkhaniyi. Mphepo nthawi zambiri imayenda kuchokera kumadera omwe mpweya uli ndi kuthamanga kwamphamvu kupita kumadera omwe mpweya uli ndi kuthamanga kwamphamvu kochepa. Kuthamanga kwa mpweya kumakhudzana ndi kuchuluka kwa mpweya kapena kulemera kwake . Pamtunda womwewo, mpweya wokhala ndi kuthamanga kwakukulu kapena kulemera kwake umakhala ndi kuthamanga kwakukulu. Mosiyana ndi zimenezi, mpweya wokhala ndi kuthamanga kochepa kapena kulemera kwake umakhala ndi kuthamanga kochepa.

Zamagetsi Zolipiritsa
Chonde yang'anani chimodzi mwa zinthu zomwe zikukuzungulirani. Ngati muwononga chinthu, mwachitsanzo mwala, mwalawo udzagawanika m'zidutswa zingapo zazing'ono. Ngati mwalawo waphwanyidwanso, mwalawo udzasanduka zidutswa zazing'ono kwambiri. Nanga bwanji ngati zidutswa za miyalazo zaphwanyidwanso? Inde, zidutswa za miyalazo zaphwanyidwa ndi kusanduka zidutswa zazing'ono kwambiri. Kodi miyala ingagawidwe m'zidutswa zazing'ono kwambiri mpaka itakhala yopanda malire? Zoona zake zikusonyeza kuti chinthu chilichonse chomwe chingagawidwe m'zidutswa zazing'ono chidzafika pamalo pomwe gawo laling'ono kwambiri la chinthucho silingagawidwe m'zidutswa zazing'ono. Gawo laling'ono kwambiri la chinthu chomwe sichingagawidwenso limatchedwa atomu. Chifukwa chake atomu ndi gawo laling'ono kwambiri la chinthu chilichonse m'chilengedwe chonse.
Malamulo a Newton
Malamulo a Newton oyendetsera zinthu ali ndi atatu, omwe ndi lamulo loyamba la Newton, lamulo lachiwiri la Newton ndi lamulo lachitatu la Newton.
Lamulo Loyamba la Newton
Lamulo Loyamba la Newton limati chinthu chilichonse chomwe chili pampando chidzakhalabe pampando kapena chinthu chilichonse chomwe chikuyenda molunjika pa liwiro losasintha chidzapitiriza kuyenda molunjika pa liwiro losasintha ngati mphamvu yonse yomwe ikugwira ntchito pa chinthucho ndi zero.
Mphamvu yokangana
Kukangana ndi mphamvu yomwe imaletsa kuyenda kwa chinthu. Mphamvu imeneyi imagwira ntchito pakati pa malo olumikizana. Munkhaniyi, kukangana komwe kwaphunziridwa kukukhudzana ndi mphamvu yomwe imagwira ntchito pakati pa malo awiri olimba omwe alumikizana, monga kukangana pakati pa maziko a chipika ndi pansi, kukangana pakati pa pansi pa nsapato ndi pansi, kapena kukangana pakati pa gudumu la galimoto ndi msewu.
Mphamvu ndi Chikhumbo
Mphamvu yolunjika
Momentum yolunjika kapena yofupikitsidwa nthawi zambiri ngati momentum imatanthauzidwa ngati zotsatira za kulemera ndi liwiro.
p = mv
Kufotokozera: p = mphamvu, m = kulemera (kilo), v = liwiro (mita/sekondi)
Momentum ndi kuchuluka kwa vector kotero kupatula kukhala ndi kukula, momentum ilinso ndi komwe ikupita. Kulunjika kwa momentum kuli kofanana ndi komwe ikupita liwiro la chinthu kapena komwe ikupita.
Lamulo losunga mphamvu zamakanika
Chiphunzitso cha mphamvu ya ntchito-kinetic chimati ntchito yonse, kapena khama lochitidwa ndi mphamvu ya net force pa chinthu, ndi lofanana ndi kusintha kwa mphamvu ya kinetic ya chinthucho. Ngati mphamvu ya net force ikugwira ntchito yabwino (mphamvu ya net force ili mbali imodzi ndi kusamuka), ndiye kuti mphamvu ya kinetic ya chinthucho imawonjezeka. Mosiyana ndi zimenezi, ngati mphamvu ya net force ikugwira ntchito yoipa (mphamvu ya net force ili mbali yosiyana ndi kusamuka), ndiye kuti mphamvu ya kinetic ya chinthucho imachepa.
Khama ndi mphamvu
Ngati mutakankhira buku patebulo mpaka litasuntha, mukugwira ntchito pa bukulo. Ngati chinthu chagwera padziko lapansi chifukwa chakuti chakokedwa ndi mphamvu yokoka, ndiye kuti mphamvu yokoka imagwira ntchito pa chinthucho. Mosiyana ndi zimenezi, ngati mutakankhira chinthu ndi mphamvu zanu zonse mpaka mutanyowa ndi thukuta koma chinthucho sichisuntha, ndiye kuti simunagwire ntchito pa chinthucho. M'moyo watsiku ndi tsiku, anthu ena amanena kuti mwagwira ntchito kapena mwagwira ntchito molimbika kuti mukankhire chinthucho, koma malinga ndi sayansi , simunagwire ntchito pa chinthucho chifukwa chinthucho sichimasuntha.
Kuyenda kozungulira kofanana
M'miyoyo yathu ya tsiku ndi tsiku, nthawi zambiri timakumana ndi zinthu zomwe zimayenda mozungulira. Chitsanzo chimodzi cha chinthu chomwe chimayenda mozungulira ndi dzanja lachiwiri, dzanja la mphindi, ndi dzanja la ola pa wotchi ya analog. Dzanja lachiwiri nthawi zonse limayenda ngodya ya 360 ° mu masekondi 60 (mphindi imodzi) kapena ngodya ya 6 ° mu sekondi imodzi. Dzanja la mphindi nthawi zonse limayenda ngodya ya 360 ° mu mphindi 60 (ola limodzi) kapena ngodya ya 6 ° mu mphindi imodzi. Dzanja la ola nthawi zonse limayenda ngodya ya 360 ° mu maola 24 (tsiku limodzi). Ngati chinthu chimayenda mozungulira nthawi zonse, monga dzanja lachiwiri, dzanja la mphindi, kapena dzanja la ola, ndiye kuti zinthuzi zimanenedwa kuti zikuchita kuyenda kozungulira kofanana . Kodi mungatchule chitsanzo cha kuyenda kozungulira komwe mwawona kapena kuganiza?
Lamulo la Hooke
Ngati mutambasula lamba wa rabara kapena tayala la rabara kufika pamalo enaake, lidzatambasuka. Mukatulutsa mphamvu, rabala idzabwerera kutalika kwake koyambirira. Mofananamo, mukatulutsa kasupe, idzatambasuka. Mukatulutsa, idzabwerera kutalika kwake koyambirira. Kasupe kapena rabala idzatambasuka ikatambasuka ndipo idzabwerera kutalika kwake koyambirira mphamvu ikatulutsidwa chifukwa ndi yotanuka. Kutanuka ndi kuthekera kwa chinthu kubwerera ku mawonekedwe ake oyambirira pamene mphamvu yomwe imagwiritsidwa ntchito pa icho yachotsedwa.
