Inertia amandla

Xa ucinga yintoni na amandla inertia (SI), ukungaqondani akholisa ukubakho, okukhokelela pseudo yesayensi-ezeza eziphikisanayo. Makhe sijonge kulo mba ngokusebenzisa indlela yenzululwazi umgwebele zonke fomyula axhasayo utshilo.

Amandla inertia ngeenxa zonke kuthi. obubonakala, abantu baqaphela kumaxesha amandulo, kodwa abazange bakwazi ukuchaza. Kakhulu ukuba zifundwa UGalileo, eyaziwa ngoko Isaak Nyuton. Kungenxa ingcaciso elide baba kunokwenzeka hypothesis ngempazamo. Oku kakhulu zendalo, ngokuba nzulu wenza eli cebiso, kunye nolwazi ezingasetyenziswanga imithwalo zenzululwazi kule ntsimi asikho.

Newton ixoxe ukuba impahla zendalo zonke izinto eziphathekayo kukukwazi ube ukwimeko sentshukumo efanayo kumgca ngqo okanye ukuphumla, ukuba kungabikho impembelelo yangaphandle.

Makhe ngokusekelwe kulwazi yangoku "ukwandisa" le vekeleke xona. Nkqu uGalileo Galilei wabonisa ukuba amandla inertia sihlobene ngqo womxhuzulane (umtsalane). A izinto etsala zendalo, isiphumo leyo izicacele - kuba iplanethi kunye inkwenkwezi (ngenxa ubunzima wayo). Yaye ekubeni babe imilo ungqukuva, ngoko uze ube UGalileo. Kodwa Newton okwangoku atyeshelwa ngokupheleleyo.

Ngoku siyazi ukuba indalo yonke into luphokoke ngemigca omxhuzulane ngegalelo lazo. Ngokungangqalanga ozinzisiweyo, nangona ngokwezibalo kwaba ubukho radiation omxhuzulane. Ngenxa yoko, amandla inertia kusoloko kusenzeka ngoncedo womxhuzulane. Newton xa Ingqikelelo sakhe "iipropati yendalo 'yoko akazange acinge.

lovela Okunye ngokufanelekileyo nabanye iinkcazelo - uthe mandla a ubungakanani yomzobo ixabiso elulolwakhe imveliso ubunzima (m) lokususa umzimba kunye lunikezelo wayo (a). Ukukhawuleziswa kumda wesangqa sibhekiswe esahlukileyo, oko kukuthi:

F = m * (- a),

kuyo F, yaye - amaxabiso ezo zithwala amandla, kunye lunikezelo ngenxa; m - ubunzima umzimba ihambe (okanye iMathematical izinto point).

Ingongoma ebalulekileyo: kuba yimpazamo ukucinga ukuba lunikezelo kubangelwa kakhulu amandla, njengoko oko kusenokubonakala ngathi evela ifomula. Kungenxa yoko le nto kwathiwa «-a», kodwa «ibe» - njengoba mfana.

Physics and Mechanics unikele amagama amabini kuba nefuthe efanayo: i iseti yolungiselelo amandla inertia kunye eziphathwayo (i-PSI). Omabini la magama interchangeable. Umahluko kukuba lokuqala ukhetho waziwa kwaye asetyenziswe ngexesha ubucukubhede. Ngamanye amazwi, le ukulingana:

F Kor = F = m * ngamnye (- a Kor) = m * (- a per),

apho F - amandla iseti yolungiselelo; F ngalinye - ethwele amandla inertia; a Kor kunye nganye - engqinelanayo zithwala lunikezelo.

PSI iqulathe amacandelo amathathu: amandla centrifugal of inertia, le translational kunye ejikelezayo SI. Ukuba lokuqala ikholisa ngokulula ukwenza loo nto, ngoko abanye ababini zifuna ingcaciso. amandla inertia Translational umiselwa yokunyusa nkqubo ngokuphathelele inkqubo inertial ngexesha iintlobo motion translational. Ngako oko, kukho icandelo yesithathu unikezelo elivela xa umzimba iyajikeleza. Ngelo xesha, ezi imikhosi ezintathu khona ngokuzimeleyo, ngaphandle kokuba yinxalenye PAN. Bonke bephela zimelwe enye indlela efanayo esisiseko F = m * a, neeyantlukwano kuphela uhlobo lunikezelo nto leyo, kuxhomekeke kuhlobo motion. Ngenxa yoko, ukuba ityala ekhethekileyo ye iseti yolungiselelo amandla ka inertia. Ngamnye kubo inxaxheba ekubaleni ukukhawulezisa ithiyori elililo komzimba eziphathekayo (amanqaku) kwinkqubo reference esisigxina (ayibonakali kusakhelwa kwenkqubo non-inertial).

PSI efunekayo xa kuqwalaselwa isindululo malunga ukwenza intshukumo yomzimba neefomula inkqubo non-inertial kufuneka ithathele ingqalelo kungekuphela nje namanye imikhosi eyaziwayo, kodwa yayo (F Kor okanye F ngamnye).
