Wokugqwayiza amandla

On the izinkundla mbumbulu wesayense imvamisa emangalisayo okhela mpikiswano ebalulekile ngalokho iyona wokugqwayiza amandla, futhi yiziphi izinhlobo zako ebonakalayo. Naphezu yobudala okutholakele zayo zihlaba - mkhuba uye wachazwa njengomuntu ekuseni njengoba 1833 - abanye abantu ngezinye izikhathi kwengqondo iziphetho. Ngokwesibonelo, kusukela iningi amandla wokugqwayiza elihlobene ne izenzakalo izilwandle nasemkhathini, kwi-inthanethi ungathola isimangalo ukuthi ingalimaza ka amandla ngamanzi osebeni lwemifula we Nenkabazwe kwenzeka ohlangothini lwesokudla, futhi Southern isinyathelo scouring amanzi ogxile ngebhange ngakwesokunxele. Abanye baye bame kwelokuthi lokhu mkhuba udala amandla wokugqwayiza. Kubaphikisi babo ukuchaza konke okunye: kusukela ukujikeleza eqinile planethi ihamba kancane ngokushesha (inertia ngaphansi) kuka isisindo amanzi futhi ngenxa yalesi umehluko kuyinto esikhundleni. Nakuba ezinye izinqubo ezenzeka olwandle, ngempela, "icala" we wokugqwayiza amandla. Ubunzima ekunqumeni ke kwibanga namanye amathonya. ukubonakaliswa wokugqwayiza njengoba amandla adonsela phansi ukuxhumana ezingaba khona.

Ake uchaze ukuthi uhlobo amandla, futhi kungani kuyinto leso sithakazelo. Njengoba iplanethi yethu kungaba kubhekwe uhlelo non-inertial (hambisa futhi Phendula), khona-ke iyiphi inqubo, kubukwe maqondana ke, kufanele acabangele inertia. Ngokuvamile esetshenziselwa echaza lokhu ikakhulukazi pendulum obuphelele okukhulu kuka-50 m kanye isisindo amashumi amakhilogramu. Ngaphezu kwalokho, isibukeli kuqhathaniswa umile emi phezu indiza phansi lapho senhliziyo pendulum uzungeza circumferentially. Uma ukubaluleka ijubane ukujikeleza planethi kungaba ephakeme kunaleyo kwenkathi oscillation we-pendulum, indiza yayo esinikelweko uzobe dengwane bebheke Nenkabazwe, ujikeleze okuphambene, ohlangothini amahora intuthuko. Ngakolunye uhlangothi, okwandisa kwesikhathi ingaphezu kwe Ukujikeleza izinga umhlaba kuyoholela Ushintsho kokuqondisa yezokuvakasha ngokwewashi. Lokhu kwenzeka ngenxa yokuthi ukujikeleza iplanethi ohlelweni kudala ukusheshisa ukujikeleza we-pendulum, a vector okuyinto usekhuluma indiza ugingqe.

Ukuchaza, ungasebenzisa isibonelo impilo. Ngokuqinisekile, ngamunye njengoba ingane egibele carousel, okuyinto ujikelezisa ngayo umuntu othile Isivinini emincane enkulu eyisicaba. Cabanga ngamaphuzu amabili disc, omunye eduze eksisi central (A) kanti eyesibili - onqenqemeni eduze engaba (B). Uma umuntu isezingeni endaweni A, enquma ukuthuthela endaweni B-ke, Uma unganakile, elilungile kakhulu ukunyakaza endleleni umugqa oA kuzo zonke izifundo-B empeleni engaba disk. Kodwa nge isinyathelo ngasinye umuntu iphuzu B kugudlukela, njengoba disc is ukuphotha. Ngenxa yalokho, uma siqhubeka iqhubeka ezihlelelwe lomugqa engaba, ukuthi uma lo engaba iphuzu B, sasingasadingeki. kungaba ubangelwa ukuchema. Uma abantu ngeke ulungise indlela yabo ngokuhambisana nesimo langempela B ke trajectory uyodala umugqa lwalugobile, kwakusondela igagasi, phezulu lapho sibhekiswe isiqondiso ukuzungeza. Nokho, kukhona indlela ukusuka A to B emgceni locondzile: kuyadingeka ukwandisa ukuthi lingakanani ijubane lokuya, etshela umzimba (umuntu) ukusheshisa. Nge ibanga okwandisa A-B ukulondoloza ukunyakaza rectilinear oludingekayo kuwo wonke okwandisa kokushaya kwenhliziyo. Umehluko sichazwe amandla centrifugal kuleyo isiqondiso eqondana yokugcina nge engaba ku selilonke ligijima.

Ngakho, siqhubekele into ujikelezisa ine umphumela wokugqwayiza amandla. Ifomula ke elandelayo:

F = 2 * v * m * cosFi,

lapho m - mass umzimba ezihambayo; v - ijubane lokuya; cosFi - Inani okuyinto uyakucabangela igebe eliphakathi ohlangothini ukunyakaza futhi eksisi ujikeleza.

Noma, Vector ukumelwa:

F = - m * a,

lapho - ukusheshisa wokugqwayiza. "-" kuphakama uphawu ngoba amandla kusuka emzimbeni ezihambayo kolunye uhlangothi.
