Inani amandla mechanical izidumbu kanye nezinhlelo

Inani okuyinto ilingana isigamu umkhiqizo nenqwaba umzimba kule Isivinini umzimba yisikwele, ubizwa ngokuthi nokwakheka energy kinetic zomzimba noma amandla isinyathelo. Guqula noma simo esishubile of a energy kinetic noma ehamba umzimba isikhathi esithile kuyoba ilingane umsebenzi oye kufezeke esithile kunqunywa amandla ayisukumele umzimba unikezwa. Uma umsebenzi webutho endleleni avaliwe noma yiluphi uhlobo kuyoba ilingane no-zero, umphumela lolu hlobo ibizwa ngokuthi ibe amandla. Umsebenzi we ezinjena kuphoqa ezingaba ngeke kuzoya ngokuthi umzimba ihamba endleleni. Umsebenzi onjalo kunqunywa kokuqala isikhundla umzimba nesiphetho isikhundla salo. Iphuzu imvelaphi noma uziro amandla ezingaba ingakhethwa ezinqumela ngokuphelele. Inani okuyinto ilingana umsebenzi owenziwa ibutho lungaba ezihambayo umzimba kulokhu kuma kuya zero iphuzu, ngokuthi yemvelo ka amandla ezingaba zomzimba noma amandla isimo.

Ukuze izinhlobo ezahlukene amabutho ku physics kukhona amafomula ezihlukahlukene ukubala amandla ezingaba yomzimba noma umile.

Umsebenzi owenziwa amabutho ezingaba, kuyoba ulingana ushintsho bezikhali amandla, okumele zithathwe uphawu obuhlukile.

Uma ufaka i-energy kinetic abangaba yomzimba, uthola inani ibizwa ngokuthi amandla Imininingwane mechanical emzimbeni. Embusweni lapho uhlelo emizimbeni eziningana is alondolozwe, ngoba kumane nje umthetho ukulondolozwa amandla mechanical noma ukuqinisela. uhlelo okulondoloza zemizimba - kuyinto uhlelo zemizimba, okuyinto kuncike isenzo kuphela amabutho ezingaba ukuthi bazimele abekho isikhathi.

Umthetho ukulondolozwa amandla mechanical noma ukuqinisela simi ngale ndlela: "Phakathi nakho konke izinqubo ezenzeka uhlelo zemizimba, amandla alo Imininingwane mechanical ayiguquki njalo." Ngakho, amandla Imininingwane mechanical lonke noma iyiphi inhlangano noma yiluphi uhlelo umzimba alushintshi, uma uhlelo emizimbeni olandelanayo.

Amandla mechanical engasekelwe ohlelweni ukuthi siqukethe n amaphuzu, ngokuqhubekayo uxhumana, kuba isamba fixed amandla ezingaba futhi kinetic kohlelo ukushayela amaphuzu. Uma uhlelo kulawa itholakala emkhakheni zangaphandle, okuyinto igcinwe noma amandla njalo-ke amandla Imininingwane mechanical uhlelo ilingana nenani lezinombolo of the fixed amandla ezingaba futhi kinetic we ukushayela ne Ngaphezu ke amandla ezingaba kohlelo inkambu zangaphandle. Uma ekhona ohlelweni namabutho non-ngoludala, kuyilapho amandla Imininingwane mechanical isistimu ingakwazi zigcinwe, bese siqala wehlise nokwehla salo umsebenzi amabutho non-olandelanayo kulesi simiso.

Uma uhlelo kuyizinhlayiyana ezosebenza amabutho non-olandelanayo kuphela, isamba amandla ezingaba futhi kinetic uyakusindiswa. Kodwa kungase kube interconversion eneji ohlelweni. Neqiniso lokuthi amandla uguqulwe kinetic futhi kinetic - e amandla ezingaba khona.

Umthetho ukulondolozwa noma ukuqinisela wezindleko noma wonke amandla mechanical uhlale invariant, okusho ayishintshi uhlobo lwaso lokubhala, ngisho noma ngabe esizoqala kuso ukubala countdown. Lo is phetho yomthetho homogeneity isikhathi.

Lapho uhlelo uqala usebenza amabutho dissipative, ezifana amandla ngomshikisho ukuthi kwenzeka kancane kancane ukunciphisa noma ukubola amandla mechanical uhlelo evaliwe. Le nqubo ibizwa ngokuthi amandla ukushabalalisa. uhlelo Dissipative - uhlelo lapho amandla zingancishiswa ngokuhamba kwesikhathi. Phakathi ukushabalalisa ka ukuguqulwa okuphelele amandla mechanical uhlelo kwenye. Lena ngokugcwele kuhambisana namandla umthetho jikelele. Ngakho, ngokwemvelo azikho izinhlelo olandelanayo ngokugcwele. Kuyadingeka yiluphi uhlelo zemizimba noma amaphuzu impahla kuzokwenzeka noma ukuthi ukushabalalisa amandla.
