Pendulum Operating - vibration amplitude

Phakathi "engunaphakade 'ukuze" iyehla iyenyuka "ingxenye esikoleni ohlelweni Physics mhlawumbe nostalgic kakhulu - ngaye njalo wakhumbula nokudabuka afudumele. Akunakwenzeka ukuthi ngisho umuntu ekhumbula isihloko akaboni, okokuqala, tick-tock, tik- ngakho ... pendulum - "ngobuqotho ngokuphelele" unit kusukela iKhabhinethi physics. Nokho, i-laboratory pendulum "ngophawu", kodwa imibono yayo zakudala medieval Kubonakala sengathi njalo ngithi, unyakazisa, akhe angunaphakade umkhaza tock, tik- ngakho ... "Ningacabangi ukuthi imizuzwana phansi." Umsebenzi lezi amadivaysi linesizotha ezibukeka - bakhombise ukuthi kuba - iyehla iyenyuka.

Siyaqonda emhlabeni, futhi sibona ukuthi kusho okukhulu kangakanani elisizungezile isinyathelo elula futhi kube lula. Ukuguquguquka - lokhu pendulum Foucault, namahora, futhi ugesi, umsakazo, i-TV, umsindo emahlaya langadzingeki mobilka ozithandayo - wonke isixuku esingaka oscillatory izinhlelo. Khona-ke, masikhumbule kwalokho okwakufundiswa esikoleni - amplitude vibrations, amafomula, amagrafu. Ngakho, lokhu kunyakaza ... kuyini na?

Konke elisizungezile kuyinto "iphuzu impahla", okuyinto, ngasizathu simbe, lokhu akuzange kunambitheke namanje. Ngo nezinxushunxushu, ukuhlukahluka ukunyakaza kunyakaza ngokuthi inqubo lapho iphuzu impahla, ngezinye izikhathi ibizwa ngokuthi uhlelo ubuyela yakhoibrium yayo isikhundla uma kuphambuka izikhathi eziningi ngaso sonke isikhathi. Ubukhulu kuka esiphezulu kusukela iphuzu yakhoibrium kuyinto amplitude oscillation. Insimbi engcono khombisa kunyakaza mechanical, Yiqiniso, pendulum ezimnandi zakudala - Georgia (ibhola, disc noma induku), okwesikhashana by intambo. Lungisa namanje - futhi lapha isimo zilingana. Thatha load ecaleni kanye ukuyidlulisa yilokho okubonayo? Kunjalo, sizoqala "uphawu-tock" alo: ukubuya kwindawo yakhoibrium, baphambukile kolunye uhlangothi, abese ephinda ebuyela isikhundla zilingana. Uma pendulum into ukuvimbela, wayesebanga kuyinto ukubuyisa futhi baphambukile, kuse ecaleni ... nokunye ngokuqhubekayo kuze, ngenxa ibutho kokukhuhlana, namanje akazange ayeke.

Manje-ke kwenzeka ukuthi iyiphi into kokuba mass, usayizi kanye nezinye izici, kufanele iqukathe iqoqo izici ezingase oyingqayizivele ukuchaza lokhu "iphuzu impahla" ukuze ukuziphatha yayo kusukela nokuxhumana imvelo waba esivikelekile, okunengqondo futhi kuyaqondakala. izici ezinjalo pendulum oscillation amplitude nesikhathi. Okunye imingcele evame ukusetshenziswa - lama-derivatives yolimi lokuqala, bona ziyingxenye ebalulekile wabo (isigaba) noma umphumela izibalo olwengeziwe (imvamisa).

Isinyathelo esilandelayo ukufunda emhlabeni ethakazelisayo kunyakaza - ukuhlola okulula ukucacisa kwemigomo into wethu - pendulum. kudivayisi pendulum kulula ndawo - ntambo ball, iphuzu ukumiswa. Indlela yokuthola amplitude oscillations of a pendulum? Yebo, kulula kakhulu, kulesi simo, njengoba besho, futhi ekhishini ongawenza. Konke Kulula (ngaphakathi kwemingcele ethile). Inkinga yokuqala: kukhona pendulum okwesikhashana ophahleni - disc metal kuchungechunge. Sinesithakazelo ukubaluleka lokuchezuka disc kusukela isikhundla zilingana. Lapho pendulum umile kwenza inothi ibhalansi iphuzu odongeni, noma iqoqo ngemuva kwesikrini ephepheni. Push-disc. I-pendulum uzoqala oscillate, nethunzi disc ngeke "ukudweba" trajectory esikrinini. Ukuhambisa induku (unga ipensela) esikrinini, sithola endaweni yokugcina, lapho emthunzini oscillations ku nephuzu ukuvala lokuqukethwe, futhi kusala uphawu. Ibanga kusukela iphuzu yakhoibrium ukuba uphawu kanye amplitude oscillations intando pendulum. Yiqiniso, kulula? Obani abangathanda sokungabaza.

Yiqiniso, kungenzeka ukuba "nesimanje" ukuhlola kanye nezikhencezo electronic nesithombe kuzwakala izinzwa noma usebenzise laser imitha ibanga, efinyelela ezinye izibalo ezikhangayo emva iphuzu zamadesimali, kodwa lutho Ungashintsha essence yayo - a isilinganiso ukuphambuka kunazozonke pendulum kusukela isikhundla yakhoibrium, okungukuthi, amplitude elinganisiwe. Umsebenzi esinayo okuhlangenwe nakho ukuze uzitholele 'ziyimfihlo' we-pendulum - the oscillation amplitude kuncike kuphela izimo kokuqala, okungukuthi, Eqinisweni amandla ngiyibona kuqala, okuyinto Uphule zilingana noma kokuqala amandla okuxhunywana uhlelo oscillating lapho pendulum is baphambukile ngumuntu engela ezithile kusukela yakhoibrium yayo isikhundla.
