Kusanthula kwa miyeso mu fizikisi kungagwiritsidwe ntchito kuwona kulondola kwa zotumphukira za equation. Mu kusanthula kwa miyeso, kuchuluka kwa thupi kokha komwe kuli ndi miyeso yofanana ndi komwe kungawonjezedwe, kuchotsedwa, kapena kufanana. Ngati kuchuluka kwa thupi komwe kuli ndi miyeso yofanana kapena yosiyana kwachulukitsidwa, kugawidwa, kapena kukwezedwa kukhala mphamvu, miyeso ya kuchuluka kumeneko imachulukitsidwanso, kugawidwa, kapena kukwezedwa kukhala mphamvu.

Kuchulukana
Chimodzi mwa zinthu zofunika kwambiri pa chinthu ndi kuchuluka kwa zinthu, komwe kumatchedwanso kuti kuchuluka kwa zinthu. kuchulukananya. Mawu osangalatsa ndi kuchulukana. Kuchulukana ndi chiŵerengero cha kulemera ndi kuchuluka kwa chinthu. Mwa masamu, zalembedwa:
ρ = m/V
(ρ werengani “rho”) ndi chilembo cha Chigiriki chomwe chimagwiritsidwa ntchito kwambiri pofotokoza kuchuluka kwa anthu, m ndi kulemera ndipo V ndi voliyumu.
Dongosolo la mayunitsi apadziko lonse lapansi kuchulukana ndi ma kilogalamu pa mita imodzi (kg/m2)3). Pa mayunitsi a CGS, omwe ndi masentimita, magalamu, ndi masekondi, gawo la kuchuluka kwa kachulukidwe limafotokozedwa mu magalamu pa sentimita imodzi (gr/cm3).
Chifukwa chiyani zinthu zolimba zimayandama pamwamba pa madzi?
Kodi munayamba mwadzifunsapo kuti, N’chifukwa chiyani zinthu zolimba zimayandama pamwamba pa madzi? Mukayika chitoliro m’madzi ndipo chitolirocho chimayandama. Kumbali ina, ngati muyika singano kapena mwala wosokera m’madzi, singano kapena mwala wosokera umamira, ngakhale kukula kwa singano kapena mwala kuli kochepa kuposa chitolirocho. Ndi zinthu ziti zomwe zimapangitsa chinthu cholimba kuyandama pamwamba pa madzi?
Mphamvu yokoka ya dziko lapansi imagwira ntchito pa chinthu chilichonse chomwe chili pamwamba pa dziko lapansi, motero chinthu chilichonse chokhala ndi kulemera chimakhala ndi mphamvu yokoka. Ngati mphamvu yolemera (w) ya chinthu cholimba ndi yocheperapo kuposa mphamvu yoyandama (F A ) ya madzi, ndiye kuti chinthu cholimba chikamizidwa m'madzi, chinthucho chimakwera mmwamba ndikuyandama pamwamba pa madzi.
N’chifukwa chiyani pamwamba pa phirili pamakhala kuzizira kwambiri?
Kodi munayamba mwadzifunsapo chifukwa chake kumakhala kozizira kwambiri pamwamba pa phiri? Nsonga za mapiri kapena mapiri nthawi zambiri zimakhala zozizira kuposa mpweya m'madera otsika kapena pafupi ndi nyanja. Malo okwera kwambiri pamwamba pa nyanja, mpweya wozizira kwambiri pamenepo. Mpweya pamwamba pa phiri uyenera kukhala wofunda chifukwa uli pafupi ndi dzuwa. N'chifukwa chiyani kumakhala kozizira kwambiri pamwamba pa phiri?
Malinga ndi lamulo la Newton la mphamvu yokoka , kukula kwa mphamvu yokoka ya Dziko Lapansi pamalo kumafanana kwambiri ndi sikweya ya mtunda pakati pa pakati pa Dziko Lapansi ndi malo amenewo. Choncho malo akakhala kutali ndi pakati pa Dziko Lapansi, mphamvu yokoka ya Dziko Lapansi pamalo amenewo imakhala yochepa. Mwa kuyankhula kwina, malo okwera pamwamba pa nyanja, mphamvu yokoka ya Dziko Lapansi imakhala yochepa kwambiri pamalo amenewo. Choncho mphamvu yokoka ya Dziko Lapansi pamalo omwe ali pafupi ndi nyanja kapena m'madera otsika ndi yayikulu kuposa mphamvu yokoka ya Dziko Lapansi pamalo okwera kapena pamwamba pa phiri.
Kulimba mtima
Chitani izi motere.
Ikani cholemera pa dynamometer ndipo lembani kulemera komwe kwasonyezedwa ndi dynamometer. Kenako, ikani kulemerako m'madzi ndikulemba kulemera komwe kwasonyezedwa ndi dynamometer.
Yerekezerani miyeso yanu. Kodi kulemera kwake kumakhala kwakukulu ngati kuli m'madzi kapena ngati sikuli m'madzi? Chifukwa chiyani? Kambiranani zotsatira za kuyesera uku ndi mnzanu.
Mphamvu Yachibadwa
Mphamvu yachibadwa ndi mphamvu yomwe imagwira ntchito pazinthu zomwe zakhudzana, komwe komwe mphamvuyo ikupita ndi mzere wolunjika ku malo olumikizirana. Chizindikiro chake ndi N ndipo dongosolo lapadziko lonse la mayunitsi ndi kg m/s 2 kapena Newton.
Kanikizani N pamalo osalala
N ndi mphamvu yochokera pansi pa mtengo, N' ndi mphamvu yochokera pansi pa mtengo. w ndi mphamvu yokoka yomwe imagwira ntchito pa mtengo kapena kulemera kwa mtengowo. N ndi N' ndi mphamvu zochitira zinthu, pomwe N ndi w si mphamvu zochitira zinthu.
Kalembedwe kachikale
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.
