Physical pendulum - n'elu niile ziri ezi

Fluctuations - otu n'ime ndị kasị ahụkarị ụdị n'ibu ngagharị. Ndị kasị pụta ìhè ihe atụ bụ vibrations nke rụrụ anụ ahụ pendulum. Ọ bụ ike ahụ ofu na a na eri na otu isi. Izere ihe pendulum si ya ịha ọnọdụ na-atọhapụ ya, anyị na-ekwe ka ya na-ada, ma ọdịda na-adịghị mere unu kpamkpam na on a trajectory nke hà n'ogologo uzo.

E nwere ike hụrụ usoro nke n'ịtụgharị nwere ume kinetic ike na Anglịkan. Na-ajụ ahụ pendulum, anyị na-arịọ ya ka o nwere ume. Mgbe ahụ, mgbe ọ na-tọhapụrụ, ọ na-amalite ime, na mgbe na-alaghachi ya ịha ebe ga-ọsọ kacha. N'oge n'ala ije emee n'ịtụgharị akụkụ nke nwere ume kinetic ike. Ọzọ, na-akpụ akpụ site na inertia, ahụ adahade elu elu, ruo mgbe ụfọdụ ebe ije-akwụsị. Ebe a, na kinetic ume converted azụ n'ime nwere.

Mgbe ahụ pendulum amalite ime na ndị na-abụghị direction, na ihe nile na-ugboro ugboro. N'ihi ya, anyị na-ahụ na anụ ahụ pendulum oscillates ruru ka ntughari nke nwere ume kinetic ike na mgbe azụ. The oge nọrọ na niile swings, ie, mgbe ahụ, n'oge nke ahu site wezụgara si ọ bụla mgbe nke trajectory nke ha ije, ga-alaghachi n'ebe ọzọ a na-akpọ oscillation oge. Onye kasị ukwuu ndiiche nke pendulum si ịha ebe a na-akpọ njupụta oscillations.

Im vibrations, ọkà mmụta sayensị achọpụtala na oge nke a na-ahụ pendulum, nke na ọ oscillates, bụghị yiri ka uka nke pendulum bụ naanị kpebisiri ike site na eri ogologo na uru nke osooso nke ike ndọda. The omume nke vibrations na o kwere omume na ikpe ebe ibu na-n'ịnyịnya na a spring. Na nke a, ntughari nke nwere ike nke a abịakọrọ spring n'ime kinetic ike nke ibu ije na Anglịkan.

Fluctuations nke na-eme anụ ahụ pendulum ma ọ bụ ibu na mmiri, mgbe e nweghị mmetụta nke ndị ọzọ na-agha, na-akpọ free ma ọ bụ onwe. Ọ bụrụ na ha na e ọ bụla mpụga mmetụta, na ndị dị otú fluctuations na-akpọ internally. Ruo ogologo oge n'ebe ọzọ mpụga oge ike pendulum amalite oscillate na ugboro nke a ike mmetụta. Dị otú ahụ na mmetụta nwere ike ime ka onu nke resonance.

Work na pendulum bụ nnọọ akpali ma na-nwere ike inye aka na idozi ọtụtụ nsogbu. Ịpụta ihe ọ na-echeta Foucault pendulum, nke ịga nke ọma n'ime-egosi na Earth-agbagharị. Na ihe a na-soro maka pendulum ije. Anyị na-eji ibu kwụsịtụrụ na a waya 67 mita ogologo. Dị ka atụmatụ, a pendulum ejikwara naanị ike nke mma nke Earth na-erughị ala nke waya. Adịru oscillations na a vetikal ụgbọelu ga-erukwa.

N'ala bụ a ikpo ájá na pendulum na nkọ ya mgbe na-akpụ akpụ ekpe ha akara na ya. Ọ hụrụ na ije a rụrụ bụghị nanị na vetikal ụgbọelu, ma e nwekwara a kwụ akụrụngwa. Onye ọ bụla pendulum ngagharị ndiiche bụ banyere atọ millimeters si aga trajectory hour ụgbọelu nke na pendulum oscillations ime, ọ ghọọ iri na otu degrees.

Anyị nwere ike icheta na-eji na pendulum elekere dabeere na a mgbe nile na oge nke ya oscillations. Oge a na-adabere na ogologo nke pendulum. Nke ziri ezi na nke a clocks nwere ike iru a bukwanu uru. Na 1954 na Soviet engineer Fedchenko e kere pendulum clocks, na nkenke nke bụ 0,0003 na kwa ụbọchị.

Nke ahụ bụ banyere otú i nwere ike na-akọwa ihe a na-ahụ pendulum, ya Njirimara na kwa, ekwe omume nke ya iji na sayensị na nkà na ụzụ.
