Pendulum hawlgala - Ilodanimada inayan gariirka

Ka mid ah qaybta "weligeed ah" si "isbedbedelka" dugsiga barnaamijka Physics waa laga yaabaa in ugu nostalgic - waayo isaga mar walba soo xusuusto murugo diiran qaar ka mid ah. Waa lagama yaabo in xitaa qof, dib mawduuca ma arko, in marka hore, sax-tock, tik- si ... pendulum - "halista ah" ee qaybta ka golaha wasiirada ee physics. Si kastaba ha ahaatee, pendulum shaybaarka "sax", laakiin views ay Dr Makumbe classic u muuqdaan kuwo mar walba in la yidhaahdo, ruxid, daa'imiska ah tick-tock, tik- si ... "Ha hoos ka fekeraan ilbiriqsi." Hawsha oo ka mid ah aaladaha qabyo-raadinta - si ay u muujiyaan in ay tahay - isbedbedelka.

Waxaan fahamsanahay dunida, oo aan arko sida badan waxaa loola jeedaa nagu wareegsan waa talaabo sahlan oo aan xumayn. Is beddel - this pendulum Foucault, iyo saacadaha, iyo korontada, raadiyaha, TV, dhawaaqa ka soo guddoomiyaha iyo mobilka jecel - dad oo dhan nidaamka oscillatory. Waa hagaag, ka dibna, aynu dib ugu yeeran wixii la baray in dugsiga - Ilodanimada inayan ee vibrations, habka, garaafyo. Sayidka, vibrations ah ... waa maxay?

Wax kasta oo naga wareegsan yahay "dhibic wax", taas oo, sabab qaar ka mid ah, ma weli fadhiisan. In fowdo ah, ku vibrations dhaqdhaqaaqa kala duwan loo yaqaan habka by kaas oo hal dhibic wax, waxaa mararka qaarkood loo yaqaan nidaamka had iyo jeer soo laabtay booska hoganaya ay marka duwan ka marar badan. magnitude ee kubad ugu badan ka taaganyahay nuqdad waa Ilodanimada oscillation ah. Qalabka ayaa ugu fiican si ay u muujiyaan ka vibrations farsamo, dabcan, waa pendulum wanaagsan - Georgia (ball, disc ama ul), ganaax by dun. weli hagaajin - oo halkan waa gobolka ee hoganaya. Qaado load ilaa dhankiisa daa waxa aad aragto? Taasi waa xaq, waxa ay bilaabi doonaan in ay "sax-tock": ku soo laabtay booska hoganaya ah, kubad dhinaca ka soo horjeeda, ka dibna mar kale ku soo laabtay booska hoganaya ah. Haddii pendulum waa waxba si looga hortago, ka dibna uu baaxaa mar kale kubad oo dhanka ... oo si joogto ah ilaa, ay sabab u tahay ciidamada frictional, weli ma aysan joogsan.

Waxa kaliya sidaas waxay u noqotay in wax kasta oo haysta mass, size iyo sifooyinka kale, waa in ka kooban dhowr ah sifooyinka in la si gaar ah ku tilmaami karaa "dhibic wax" si ay dabeecad ka dhexgalka la deegaanka ahaa la saadaalin karo, oo macquul ah oo la fahmi karo. sifooyinka Kuwaasi waa pendulum Ilodanimada oscillation iyo muddo. xuduudaheedu kale caadi ahaan loo isticmaalo - u taagayo ee asalka ah, inay yihiin qayb muhiim ah iyaga (wajiga) ama natiijada xisaabaha dheeraad ah (inta jeer) ee.

Tallaabada xigta waa barashada dunida xiiso of vibrations - tijaabo fudud si loo ogaado ku soo koobin of our walax - pendulum ah. qalab pendulum waa u fududahay in ay meel - kubada dun, dhibic ka joojinta. Sida loo helo Ilodanimada inayan reer oscillations of pendulum ah? Haa, si fudud, si ay u waayo-aragnimo this, sida ay iyagu yidhaahdaan, iyo jikada samayn karin. Wax walba waa u fududahay (xad). dhibaatada asalka ah: waxaa jira pendulum ka saqafka ganaax - disc biraha on dunta ah. Waxaan ku mashquulsan yihiin qiimaha leexashooyinkaasi disc laga qabto, hoganaya ah. Marka pendulum taagan dhigaysa note ah dhibic dheelitirka derbiga dul jooga, ama on set gadaashiis screen warqad ah. Riix disc ah. pendulum wuxuu bilaabi doonaa baayici karo, iyo hooskii disc ah "sawiri" doonaa dhabbihii shaashadda. Guuritaanka usha (aad qalin karto) shaashadda, waxaan ka heli dhibic ee la soo dhaafay, marka hooska oscillations ee barta xad dhaaf ah oo ku dhow naga index, oo ka dhigaysa ku ganaya. Masaafada ka taaganyahay nuqdad in ay sumaddii iyo Ilodanimada inayan reer oscillations doonistii pendulum ah. Run, waa ay fududahay? Oo kuwa shakiya lahaa.

Dabcan, waxaa suurtagal ah in ay "casriyeeyo" tijaabo la dawanno electronic iyo dareemayaal photo foorida ama isticmaal laser ah meter meel fog, si loo qiyaaso ilaa qaar ka mid ah tirooyinka soo jiidasho leh ka dib markii ay hal dhibic ka tobanle, laakiin waxba beddeli karo nuxurka - qiyaasay weecasho ugu badan ee pendulum ka booska hoganaya ah, ie, Ilodanimada inayan cabbiro. Shaqada in aan waayo-aragnimo in ay si fudud u ogaan a "qarsoon" ee pendulum ah - oscillation u Ilodanimada ku xiran tahay oo kaliya on shuruudaha hore, ie, dhab ahaantii xoogga Suu ugu horeeyay, taas oo jebisay hoganaya ama tamarta nidaamka oscillating gaadhsiiyo hore markii pendulum waxaa dhacday by xagal gaar ah laga qabto, hoganaya ay.
