Mphamvu kuthekera

Motere ku lamulo la kusamala mphamvu, thupi aliyense nthawi zonse ali mphamvu. Pamaso pa zoyenda lodziwikiratu ndi liwiro kapena mathamangitsidwe, amene kuchulukitsa ndi kulemera, amapereka mukufuna. Komabe, pamene thupi liri pa mpumulo, izo, ndi zodabwitsa, Angagwiritsidwenso yodziwika monga chopezeka mphamvu.

Choncho, mphamvu kayendedwe kumachitika pamene galimoto, kuthekera - ndi mgwirizano wa matupi angapo. Ngati woyamba kwambiri kapena zochepa kuonekera, ndi zambiri mphamvu kumachitika pakati pa zinthu ziwiri mapulani ndi chosatheka kuzindikirika.

Izo ziri zodziwika bwino kuti Earth amakhudza onse a thupi, amene ali padziko chifukwa munda yokoka. Ndiko kuti, chimakakamiza chinthu chilichonse ndi mphamvu zina. Pamene muyenda chinthu, kusintha kutalika kwake, palinso kusintha mu ntchito mphamvu. Mwachindunji pa nthawi kukweza thupi mathamangitsidwe ndi. Komabe, mfundo zake apamwamba nkhani (ngakhale kwa kugawanika wachiwiri) ndi yosasuntha, iwo ali ndi mphamvu zogonjetsera mavutowo. The chinthu, kuti akadali latsala yokha munda dziko lapansi, ndi omwe thupi anakhumba amachitira.

M'mawu ena, pali nthawi zonse mphamvu ndi kuthekera chifukwa mogwirizana kwa zinthu zingapo apanga dongosolo, mosasamala kanthu za kukula kwa zinthu okha. Pankhaniyi, kusakhulupirika mmodzi wa iwo ukufanizidwa ndi lathuli.

Angathe mphamvu - kufunika potsata misa ndi kutalika kwa chinthu chomwe liukitsidwa. Lonse lakuti - makalata EP. Chilinganizo cha mphamvu ndi kuthekera chiri motere:

EP = mgh,

Kodi mamita - misa, ga - mathamangitsidwe wa ufulu kugwa, H - kutalika.

Zofunika chizindikiro kuganizira mwatsatanetsatane kutalika, monga zimayambitsa vuto kuthetsa ndi kumvetsa kufunika kuchuluka kwa. mfundo ndi yakuti gulu lililonse ofukula za thupi ali chiyambi ndi mapeto ake mfundo. Chifukwa malo olondola a mphamvu angathe mogwirizana kwa matupi ndi kofunika kudziwa kutalika koyamba. Ngati si ananenera, phindu lake ndi ziro, kuti n'chimodzimodzi ndi padziko Lapansi. Zikatero, ngati mfundo yoyambira amadziwika buku, ndi kutalika komaliza, m'pofunika kupeza kusiyana pakati pa iwo. Ndipo chiwerengero chifukwa adzakhala anafuna h.

M'pofunikanso kukumbukira kuti mphamvu ndi kuthekera kwa dongosolo angakhale ndi phindu negative. Tinene kuti kale anaukitsa thupi pamwamba Lapansi Choncho, ali msinkhu, yomwe ife timaitcha chachikulu. Pamene adatchithisira chilinganizo amaonekera izi:

EP = mh (h2-H1).

Mwachionekere, yaitali H1 h2, chotero, mtengo ndi zoipa, ndi kupereka lonse chilinganizo opanda chizindikiro.

Modabwitsa, mphamvu angathe apamwamba, kutali pamwamba inali thupi dziko lapansi. Kumvetsetsa mfundo imeneyi, ife tikuganiza za izo: apamwamba kufunika kulera thupi pamwamba pa dziko lapansi, ntchito bwinobwino wangwiro. The apamwamba kufunika kwa ntchito mphamvu iliyonse, choncho ndi kulankhula, zazikulu mphamvu padera. The mphamvu kuthekera, mwa kulankhula kwina - ndi mwayi mphamvu.

Mofananamo, munthu akhoza kuyesa mphamvu ya zimachitika pamene matupi nkhani anatambasula.

Mu phunziro lino ayenera payokha kukambirana mogwirizana ndi tinthu mlandu munda magetsi. Chonchi dongosolo mudzapezeka kuthekera mphamvu mlandu. Taganizirani mfundo iyi mwatsatanetsatane. Pa mlandu uliwonse pano mu munda magetsi wa chomwecho dzina mphamvu zochita. Kupita particles ndi chifukwa ntchito ndi mphamvu. Popeza kuti mlandu yeniyeni wakumunda mu atomu (yeniyeni, thupi amalenga izo) - ndi dongosolo, ife kupeza mphamvu angathe mlandu ukusuntha mwa munda anapatsidwa. Popeza mtundu uwu wa mphamvu - nkhani yapadera, iye anali kupereka mutu wa electrostatic.
