Amandla emvelo

A ubungakanani ebonakalayo leyo ubonakalise umlinganiselo apho kuchaphazela umzimba okanye ukwenye intsimi emzimbeni, ebizwa amandla. Ngokutsho yesibini umthetho Newton, ukukhawulezisa ukuba ufumana umzimba umlinganiselo ngqo nomkhosi esebenza kuyo. Ngako oko, ukuze utshintshe isantya umzimba, kuyimfuneko ukuba nempembelelo ngamandla. Ngoko ke, lokwenene ingxelo ukuba amandla emvelo umthombo wabo bonke intshukumo.

isalathisi Inertial

Le amandla emvelo izixa kumda wesangqa, oko kukuthi, baye wukulu kunye nolwalathiso. Nemikhosi ezimbini ingaqatshelwa enye kuphela xa iimodyuli, kunye nezalathiso zabo ziyafana.

Ukuba umzimba lo ayichaphazeleki yimikhosi, kwakunye kwimeko apho isixa zejometri zemikhosi osebenza umzimba banikwa (eli xabiso idla ngokuba nomphumela ayo yonke imikhosi), ilingana zero, umzimba nokuba uhlala kwi ukuphumla okanye uqhubekela kwicala elinye izinga rhoqo (ngamanye amazwi, ukugudla). Eli binzana lisebenza iinkqubo reference inertial. Ubukho kweenkqubo ezinjalo Aristotle umthetho wokuqala Newton. Kwindalo, ezi nkqubo musa, kodwa ke lula imodeli zezibalo. Noko ke, ngokufuthi xa usombulula imisebenzi yeprekthikhali ireferensi nkqubo enxulumene Umhlaba, oko kuthathwa njenge inertial.

Umhlaba - inertial kunye nenkqubo reference non-inertial

Ngokukodwa, ngexesha umsebenzi wokwakha, ukubalwa ukuhamba kwezithuthi kunye ukuqubha zothutho kwingcinga yokuba Umhlaba - inkqubo reference inertial, akukho yaneleyo kunye nezisombululo eziyimfuneko ezisebenzayo kwiingxaki okuchaneka ukuchaza amandla.

Kwindalo, kukho kwakhona imisebenzi ukuba asivumeli ingcamango enjalo. Ngokukodwa, oku kusebenza kwiiprojekthi isithuba. E ukuqala kulo irula ngokungqongqo ngenxa ukujikeleza koMhlaba bumse intshukumo ibonakala kuphela ecaleni nkqo, kodwa kwicala tyaba ngokuchasene njengokujikeleza Yomhlaba. Kule intshukumo wabonakalisa nkqubo non-inertial of reference ezinxulumene iplanethi yethu.

Ngokomzimba, rocket yona ayichaphazeleki yimikhosi, kuyithumela. Noko ke, ukuba bachaze isindululo rocket iluncedo ukuba usebenzise amandla inertia. Le mikhosi azikho emzimbeni, kodwa ingcamango zabo zangaphambili ivumela ukuba ukuqalisa inkqubo inertial non-inertial. Ngamanye amazwi, xa kubalwa isikhokelo rocket bakholelwa ukuba inkqubo reference "Umhlaba" na inertial, kodwa isebenza kwi rocket amandla abathile kwicala tye. Le mandla kuthiwa amandla iseti yolungiselelo. Kwindalo, isiphumo sayo kubonakala xa kufikwa imizimba ezihambayo nomphakamo elithile ngokuphathelele umhlaba wethu ukuze ixesha elide okanye ngesantya esiphezulu. Ngoko, ke ithathele ingqalelo echaza hayi kuphela kwisindululo imijukujelwa kunye Hewana, kodwa xa kubalwa intshukumo iqokobhe zokudubula, moya, njl

Uhlobo Uthethathethwano

Yonke imikhosi bubunjani imvelaphi yayo ngokwemvelo iintengiselwano ezine ezisisiseko (umoya, omxhuzulane, ungenamandla kwaye womelele). Le macrocosm na isiphumo oqaphelekayo kuphela imikhosi omxhuzulane kunye kagesi. unxibelelwano buthathaka kwaye womelele kuchaphazela iinkqubo ezenzeka ngaphakathi eziba atomic amasuntswana eathom.

Owona mzekelo uqhelekileyo intsebenziswano omxhuzulane na amandla yomtsalane. Yeyona force apho Umhlaba usebenza kwibhunga ezingqongileyo.

imikhosi umoya, ngaphandle mizekelo ezicacileyo iquka zonke elastic ezinxulumene ngokunxibelelana uxinzelelo apho izidumbu omnye phezu komnye. Ngako oko, amandla zendalo ezifana ubunzima (force ngawo umzimba usebenza kwi ukunqunyanyiswa okanye inkxaso), zohlobo electromagnetic.
