Pendulum Physical - ngaphezu kwakho konke ukunemba

Iyehla iyenyuka - omunye lwezinhlobo ezivame kakhulu ukunyakaza lokukhanda. Isibonelo osobala kakhulu kunyakaza okuyinto wenza pendulum ngokomzimba. Kuyinto umzimba kanzima fixed kuchungechunge ngesinye isikhathi. Ukuphambukisa pendulum kusukela yakhoibrium yayo isikhundla futhi ukukhulula khona, sivumela ukuba iwe, kodwa ukuwa akwenziwa ngokukhululekile futhi kwi trajectory alinganayo obuphelele imicu.

Kube kungabonwa inqubo zokuguqula amandla ezingaba ku energy kinetic, noHezekeli. Inkosi uRehobowamu yalahla pendulum ngokomzimba, simcela ukuba amandla ezingaba khona. Khona-ke, lapho ikhishwe, iqala ukuhambisa, futhi lapho ubuyela yakhoibrium yayo iphuzu kuyoba ngesivinini esiphezulu. Phakathi ukunyakaza phansi kwenzeka ukuguqulela ingxenye engaba amandla ku energy kinetic. Ngokulandelayo, ezihambayo by inertia, umzimba liphuma njalonjalo, kuze kube esikhathini esithile ukunyakaza sithule. Lapha, i-energy kinetic is iguqulwe emuva ku-ezingaba khona.

Khona-pendulum uqala ukunyakaza kolunye uhlangothi, futhi konke siphindiwe. Ngakho, siyabona ukuthi i-pendulum ngokomzimba oscillates ngenxa wenze ukushintshela kwamandla abengase asetshenziselwe okuthile ku energy kinetic bese emuva. Isikhathi esichithwa zonke senhliziyo, okungukuthi, ke, phakathi kwesikhathi lapho umzimba ngombana wasuka yingasiphi trajectory of ukunyakaza kwabo, bayobuyela khona futhi libizwa oscillation isikhathi. Ukusuka kunazozonke pendulum kusukela iphuzu yakhoibrium libizwa oscillations kwawo namandla awo.

Ukutadisha nokudludliza, ososayensi bathole ukuthi inkathi a pendulum ngokomzimba, ngalo oscillates, akuyona okuhlobene kunobukhulu bendawo pendulum kuphela kunqunywa obuphelele wentambo ukubaluleka ukusheshisa gravity. Okuvela kunyakaza kungenzeka futhi esimweni lapho umthwalo igibele entwasahlobo. Kulokhu, ukwedlulela amandla ezingaba isiphethu onomfutho energy kinetic ukunyakaza umthwalo, noHezekeli.

Iyehla iyenyuka okwenza pendulum ngokomzimba noma umthwalo entwasahlobo, uma kungekho umphumela amabutho ezengeziwe, ngokuthi khulula noma kwangasese. Uma kubo kukhona nethonya zangaphandle, ukuthi iyehla iyenyuka zokuphumula ezinjalo zibizwa ngokuthi ngaphakathi. Isikhathi eside ukuchayeka ezengeziwe zangaphandle amandla gqwa pendulum uqala oscillate nge ukuvama kwale nethonya amandla. Nge umthelela kungabangela lo mkhuba resonance.

Sebenza nge-pendulum Kuyathakazelisa kakhulu futhi kungasiza ekuxazululeni izinkinga eziningi. Engingakusho nje kokukhumbula Foucault pendulum, okuyinto zaphumelela ukufaka ngesinyelela efakazela ukuthi Umhlaba uzungeza. Kule experiment zazilandelwa ngoba pendulum ukunyakaza. Sasebenzisa umthwalo okwesikhashana on a wire 67 budze. Ngokuya ngalolu hlelo, a pendulum eziqhutshwa kuphela amandla Luhambo Zomhlaba futhi isimo esishubile wire. Lapho oscillations e indiza mpo kumele kwenzeke.

Esitezi kwaba indunduma yesihlabathi kanye pendulum nge ekupheleni lwayo olucijile lapho Ukuhanjiswa zangishiya kuso. Kwatholakala ukuthi ukunyakaza Kwenziwa hhayi kuphela indiza mpo, kodwa kukhona ingxenye ovundlile. Ngamunye ukuphambuka pendulum ezinyakazayo kwaba mayelana ezintathu amamilimitha angu ehoreni odlule trajectory indiza lapho oscillations pendulum zenzeka, yaphenduka degrees nanye.

Singakhumbula nokusetshenziswa iwashi okuthiwa i-pendulum esekelwe isikhathi njalo oscillations yayo. Le nkathi incike ubude pendulum. Ukunemba la mawashi ongafinyelela value eside. Ngo-1954 unjiniyela Soviet Fedchenko zadalwa pendulum amawashi, ngokunemba okukhulu 0,0003 nge nsuku zonke.

Yilokho mayelana nendlela ungakwazi ukuchaza lokho a pendulum ngokomzimba, impahla yayo kanye nemingcele, kungenzeka ukusebenzisa kwayo kwezesayensi nobuchwepheshe.
