Mun yi nazari kan layi-amplitude na oscillations

Daga cikin batutuwa "na har abada" game da tsarin ilimin makaranta a kan ilmin lissafi, ɓangaren "jinkirin" shine watakila mafi mahimmanci - ana tunawa da shi kullum tare da wasu baƙin ciki. Mai wuya kowacce akalla, tunawa da wannan batu, baya ganin, da farko, kaska-tick, tick ... pendulum-na'urar "mafi tsanani" daga ɗakin lissafi. Gaskiya ne, shafukan dakunan gwaje-gwaje ba "kaskantar" ba, amma ana nuna alakarsu ta zamani ta yadda ake magana da su, suna mai da hankali sosai, har abada suna dinka-don haka, kaska ... "Kada kuyi tunani game da sannu-sannu". Kuma aikin da wadannan na'urori masu kwarewa shine ya nuna a fili abin da yake - haɓakawa.

Mun san duniya kuma mun ga yadda irin wannan aiki mai sauki da kuma rikitarwa a kusa da mu yana nufin. Shakka - wannan Foucault Pendulum, kuma hours, da wutar lantarki, rediyo, TV, sauti daga magana, kuma fi so mobilka - a duk taron oscillatory tsarin. To, da kyau, tuna da abin da aka koya a makaranta - ƙididdigar tsararraki, ƙira, fasali. Saboda haka, jinkirin ... kuma mece ce?

Duk abin da ke kewaye da mu shine "maki", wanda, saboda wani dalili, ba ya zauna har yanzu. A cikin hargitsi, da bambancin motsi vibrations kira da aiwatar da abin da wani abu batu, wani lokacin ake kira da tsarin ko da yaushe ya kõmo zuwa ta ma'auni matsayi a lokacin da shi deviates daga shi sau da dama. A wannan yanayin, girman girman iyaka daga ma'auni ma'auni ana kira amplitude na oscillations. A mafi kyau kayan aiki ya nuna inji vibrations, ba shakka, abu ne mai kyau haihuwa Pendulum - Jojiya (ball, Disc ko sanda), dakatar da wani thread. Gyara shi maras kyau - kuma a nan shi ne yanayin ma'auni. Ɗauki kaya a ajiye kuma saki abin da kuke gani? Daidai ne, zai fara sakonsa "koma-to-do": komawa matsayin daidaitawar, ya ɓace zuwa gefe ɗaya, sa'an nan kuma sake komawa matsayin ma'auni. Idan Pendulum abinda zai hana, sai ya zama m sake deflected zuwa ga gefen ... da haka ci gaba har, saboda da frictional karfi, shi har yanzu ba su daina.

Wannan ya faru cewa duk wani abu da yake da nau'i, girmansa da sauran siffofi na musamman ya ƙunshi sifofin halaye wanda zai iya bayyana wannan "matsala" ta yadda ya dace da halayyar ta hanyar hulɗa da yanayin shi ne abin iya gani, ma'ana da fahimta. Wadannan halaye na labaran sune amplitude na oscillations da lokacin. Sauran amfani da sigogi da aka saba amfani dasu suna samo asali daga ainihin su, sune ɓangaren sashe (lokaci) ko sakamakon ƙarin ƙididdiga (mita).

Mataki na gaba a cikin nazarin duniya mai mahimmanci na oscillations shine gwaji mafi sauƙi don ƙayyade sigogi na abu - abin da ke tattare. Kayan na'ura mai banƙyama ba wani wuri mai sauki, ball, maƙallin dakatarwa ba. Kuma yadda za a sami amplitude na oscillations irin wannan pendulum? Yana da sauki cewa irin wannan kwarewa, kamar yadda suke faɗa, kuma a cikin ɗakin abinci za a iya yi. Duk abu mai sauki (a cikin wasu iyaka). Aikin farko: akwai dakatar da aka dakatar daga rufin - faifai a kan zane. Muna sha'awar yawan bambanci daga cikin faifai daga matsayin ma'auni. Tare da ma'auni mai mahimmanci, mun auna ma'auni ma'auni a kan bangon, ko a kan allon takarda da aka sanya a baya. Jira da diski. Tsarin zai fara oscillate, kuma inuwa daga diski zai "zana" yanayin a allon. Matsar da wand (zaka iya fensir) akan allon, zamu sami ƙarshen maimaitawa, lokacin da inuwa tare da oscillations a matsayi mai mahimmanci rufe kalmarmu, sa'annan mu sanya alamar. Nisan daga ma'auni da ke nuna alamar zai zama amplitude daga cikin oscillations na pendulum. Shin, ba haka ba ne? Kuma wanda zai shakka.

Hakika, yana yiwuwa ya "zamanintar" da gwaji tare da lantarki karrarawa da whistles photo na'urori masu auna sigina ko amfani da Laser nesa mita, don auna har zuwa wasu m Figures bayan da gidan goma batu, amma babu abin da zai canza ta ainihi - a ji shi ne mafi girma da karkacewa daga cikin Pendulum daga ma'auni matsayi, watau, Ana auna amplitude. A cikin gwajin da muka yi, yana da sauki a gano "asiri" na layi - amplitude ya dogara ne kawai a kan yanayin farko, watau. A gaskiya daga karfi na farko girgizar da ya rikitar da jihar ma'auni, ko kuma na farko da makamashi bayar da tsarin oscillatory, a lõkacin da pendulum an karkatar da wasu kusurwa daga matsayin ma'auni.
