Amandla iseti yolungiselelo

Kwi iiforam pseudo-obunzululwazi rhoqo emangalisayo kwanokubuyisela ingxoxo enzulu malunga yintoni na amandla iseti yolungiselelo, yaye ziziphi obubonakala ezibonakalayo. Nangona ezifunyaniswe zawo ihloniphekile ubudala - nto ke iye yachazwa kwangethuba 1833 - abanye abantu ngamanye amaxesha bedidekile izigqibo. Ngokomzekelo, ekubeni inkoliso amandla iseti yolungiselelo ezinxulumene izenzakalo elwandle kunye nomoya, kwi-intanethi uyakwazi ukufumana ibango ukuba ukujongelwa lomlambo ze kumntla ikhweyitha kwenzeka kwicala lasekunene, kwisenzo Southern wokukhuhla amanzi ikakhulu phezu kodonga lasekhohlo. Bambi bathi lo meko kudala amandla iseti yolungiselelo. elinye iqela uchaze yonke into, ukusuka njengokujikeleza komhlaba eqinileyo umhlaba luba ngokukhawuleza kancinci (inertia ngaphantsi) ngaphezu ubunzima ngamanzi ngenxa yale umahluko walo endaweni. Nangona ezinye iinkqubo ezenzekayo elwandle, ngokwenene, "unetyala" yomkhosi iseti yolungiselelo. Ubunzima kulo isigqibo ngayo kwezahlukeneyo nezinye iimpembelelo. nokubonakaliswa iseti yolungiselelo njengoko amandla omxhuzulane yentsebenziswano isakhono.

Makhe ukuchaza ukuba uhlobo ngamandla, yaye kutheni inzuzo enjalo. Ekubeni iplanethi yethu ukuba ingqalelo inkqubo non-inertial (sihamba kunye Jikeleza), ngoko nayiphi na inkqubo, zingajongwa phaya ngokuphathelele kuyo, kufuneka ithathele ingqalelo inertia. kusetyenziswa Ngokuqhelekileyo echaza le ubude ethile pendulum mkhulu kwe-50 m kunye ubunzima kwamashumi kilograms. Ngaphezu koko, ukuqwalasela emileyo ngokwentelekiso emi moya kumgangatho apho kukutshintshatshintsha pendulum ujikeleza circumferentially. Ukuba ixabiso isantya ojikeleza ngaso ngenxa yomhlaba kwakuza kuba ngaphezu ngexesha oscillation ngayo kuqala, moya yayo eziqingqiweyo ziya bedinga kwicala kumntla ikhweyitha, kokutshintsha kwenye, kwicala iiyure inkqubela. Kwelinye icala, ukwandisa ixesha ingaphezulu ngokujikeleza rate umhlaba baya kwenza utshintsho bejonge ngku zokuhamba. Oku kwenzeka ngenxa yokuba ukujikeleza umhlaba kwinkqubo uyila ukukhawulezisa ojikelezayo we kuqala, eya kumda wesangqa leyo ngokutshintsha-moya onenombolo.

Ukuze achaze, ungasebenzisa umzekelo lobomi. Ngokuqinisekileyo, ngamnye umntwana ekhwele okuvezwa, nto leyo a ejikelezayo kunye ethile Velocity emboxo diski enkulu. Khawucinge iingongoma ezimbini phezu disc, omnye kufuphi esqwini central (A) kunye yesibini - emphethweni kufuphi radius (B). Ukuba umntu lowo ngaxa A, egqiba ukuya kwindawo B, ngoko, xa uqala, eyona ngokupheleleyo indlela isindululo yi umgca othe ngqo A-B ngenene radius disk. Kodwa inyathelo ngalinye umntu point B ishenxiselwe, njengoko disc ujikeleza. Ngenxa yoko, xa siqhubeka bahambe kuhlelwa umgca-radius, ukuze xa kwirediyasi kwindawo B, oko akusayi kuba ngenxa icala. Ukuba abantu baya alungise indlela yabo ngokungqinelana nemeko sezibhaliwe B, ngoko isikhokelo iya kunika umgca egosogoso, iliza, encotsheni apho sibhekiswe indlela ujikelezo. Noko ke, kukho indlela yokuba ukusuka A B kumgca othe ngqo; kuyimfuneko ukuba ukunyusa isantya intshukumo, niyixelele umzimba (umntu) unikezelo. Nge Umgama ukwandisa A-B ukugcina intshukumo rectilinear kuyimfuneko kuzo zonke ukwandisa izinga ukubetha. Umahluko sichazwa amandla centrifugal kuloo kwicala ihambelana latter embindini phezu achazwe apha olujikelezayo.

Ngoko ke, ihamba phezu into ejikelezayo onesiphumo yomkhosi iseti yolungiselelo. Ifomula kulandela:

F = 2 * v * m * cosFi,

apho m - ubunzima umzimba ihamba; v - Isantya intshukumo; cosFi - ixabiso oluthathela ingqalelo engile ephakathi ngakwicala intshukumo kunye ezimanyeneyo ujikelezo.

Okanye, bamelwe kumda wesangqa:

F = - m * a,

apho - yokunyusa iseti yolungiselelo. "-" uphawu kuvela kuba amandla ukusuka emzimbeni ihamba kwicala elahlukileyo.
