Tiyeni tione zimene amayezedwa joules

Physics - sayansi ya m'madera zachilengedwe. Mwina n'chifukwa chake iye analipira kwambiri chidwi mu njira sukulu. Ophunzira nthawi zambiri anakumana ndi funso zimene amayezedwa joules. Ndi kuchitika, kuyambira osiyana zigawo a sayansi zikuphatikizapo mtengo uwu. Komabe, ngati inu kuyesa kumvetsa pang'ono za nkhaniyi, nthawi yomweyo amakhala chirichonse mu malo ake. Kodi mukhoza kukumana zimene amayezedwa joules? Yankho si kwapafupi, koma momveka bwino.

Izo zonse akuyamba ndi chilinganizo A yosavuta = F * S. Kudalira chotero ntchito ulamuliro auŵakhe pambuyo mwezi woyamba wa chikondi ndi sayansi. Ngati inu basi kumvetsa zimene zinali kuchitika, ndiye ife tikhoza kuyamba bwino kudziŵana ndi sayansi. F - Uwerenge mphamvu zonse yogwira ntchito kwa thupi, amene zimakhudza kusintha malo thupi. Iwo amayezedwa Newtons. Chiweruzo chimene mphamvu amayezedwa joules, sizolondola. S - njira imene yapitayi thupi. Mu mayunitsi SI, izo akusonyeza meters. Choncho, 1 J = 1 N * 1 m. Zimenezo zoona, tapeza ntchito ku mfundo thupi la view. Zilibe kanthu ndi amene ndi m'mikhalidwe zimene zonse.

Komanso, monga ulamuliro, mu chitatu kuphunzira kalasi njira matenthedwe. Apa ife timathandiza mfundo zambiri latsopano. Dongosolo ili: Q = cm (T1-t2). Apanso funso n'lakuti zimene amayezedwa joules mukudalira izi. Ndipo mwa njira, tikuona kuti panali zovuta kuzimvetsa variable c. Ndipotu, ndi kutentha enieni zinthu. Dziwani kuti nthawi zambiri nthawi zonse, kuyeza kwa nthawi yaitali. gawo ake: J / (makilogalamu * KUSIYANA Celsius). Motero n'zosavuta kuona kuti m'pofunika kuchulukitsa mtengo uwu ndi kulemera ndi kutentha zina, adzatembenuza joules. Kuti ndi kalata Q. Ndi muyeso iwo. Akuti zoona kutentha - mphamvu. Mwachitsanzo, mu injini kuyaka mkati koyamba allocated Q, kenako atuluka ndi ena Mwachangu mu A = F * S. Against ichi, mfundo akuchokera Olympiad mavuto ena ophunzirawo 7-8.

gawo lina lalikulu, amene ayenera kuonedwa kuti tipeze chimene amayezedwa joules, ndi "Magetsi". Kumene, mu chimango kwambiri padziko lonse lotchedwa pang'ono mosiyana, koma sukuluyi ndi mankhwala abwino akuti zimenezi. Anthu ambiri akudziwa zimene mfundo zachokera nyali incandescent. Kumene akubwera kutentha mphamvu? Inde, magetsi amachita ntchito ina, sipangakhalenso masamu ndi chilinganizo A = Ine Ine T * T. Kodi T - nthawi, I - panopa mwamphamvu, R - kukana. Apa, ntchito Anayezanso mu joules.

Sitingathe kunena za zimango, imene kuchuluka mu funso ntchito ndithu. Nthawi zambiri, mavuto kusukulu n'zomveka kuti chilamulo cha kusamala mphamvu. Kotero mphamvu izi ndi ndendende amayezedwa joules. Tanthauzo lenileni la mawu a chilamulo ndi thupi ali ngati mphamvu zoyenda, njira matenthedwe ndi njira zina thupi. Ndipo ngati Mwachitsanzo, chidutswa cha nkhuni zithunzi pamodzi pamwamba ndi mabasi, sizitanthauza kuti wotaya mphamvu. Iye umangopitirira ntchito kukhululukirana.

Kotero, inu mukudziwa, kuti amayezedwa joules. Monga mmene taonera, khalidwe ili ntchito mu nthambi zosiyanasiyana kwambiri za sayansi. Komabe, ngati inu kumvetsa kwenikweni kuti n'kosavuta.
