Yintoni na iziko ubunzima?

Igama elithi "iziko mass" lisetyenziswa nje kuphela ukukhanda, kwaye ekubaleni intshukumo ye imizimba yasezulwini, kodwa kubomi bemihla ngemihla. Nje abantu abasoloko ucinge ngoko ke imithetho yendalo wabonakaliswa kwimeko ethile. Umzekelo, emkhenkceni inani ngababini bethatha usebenzisa iziko ubunzima, xa ukujija, bebambene ngezandla.

Eku sunguleni, phambi kokuvulwa umthetho Newton womxhuzulane, kwaye babecinga ukuba umhlaba nazo zonke iiplanethi zenkqubo enye ixhomekeke kwenkwenkwezi central - ilanga. Oko kukuthi, indawo kwindawo iziko ingqamana kwiziko ebonakalayo lokubonakala kwenkwenkwezi. Isondlo, sasingakwazi kunokwenzeka. Kodwa ke Newton wabonisa ukuba izinto azikhethe ninomdla omnye komnye - hayi nje ilanga kube nefuthe kwi emhlabeni, kodwa ichaphazela inkwenkwezi lokugqibela. Ekubeni ifomula iqulethe nje isikweri mgama, kodwa ubunzima, impefumlelwano zemikhosi ezingalungeleleneyo. Isiphumo kukuba kumbindi ubunzima inkqubo ngoomatshini "Ilanga-Umhlaba" ayikho embindini lokubonakala kwenkwenkwezi, kwaye lisisiqalo ngokunxulumene kwiziko emzimbeni. Ngoko ke yodwa le ngongoma njengoko uMhlaba kunye ilanga ngokwayo.

Iziko of mass kuqala ukuba iqalise, ngoko krelekrele ukuqinisekisa ubukho kwenkqubo lokubonakala kwenkwenkwezi Sirius neqabane avulekile. Okwenzeka intshukumo iinkwenkwezi, ngeenkwenkwezi wabona intshukumo yakhe ngumtshangatshangiso-like engaqhelekanga. Ndafumanisa ukuba Sirius - yinkwenkwezi kabini. Bona benza emhlabeni iziko ubunzima, nto leyo ebangela ukwehla kubonwa.

Eli liziko ubunzima izimele ngokupheleleyo uhlobo lonxibelelwano ziquka mhlaba otsalayo, intambo, ngentonga. Bonisa iibhola ezimbini ezinobunzima M1 kunye m2, ezidibene enye ubude ngalinye ebuntsimbi ukukhanya intonga L. Le yinxalenye isantya singaneli kunabela M1 ibhola, ukuba kudlule kunye m2. Ukuba ngoku bayeke eli qela iibhola emoyeni kwi-engile, i yeflaythi kuphela xa uqala kubonakala abathathela: nangona i "somersault" iibhola, ukutshintsha indawo yabo, abanye kwincopho eqhelekileyo kwi intonga into ihamba ngendlela ekumele - phezu indlela ezizekelisayo. Eli ke liziko mass. Yena akukho mfuneko ise-ziko. Umzekelo, kwi umzekelo iinkwenkwezi kubhaliwe ise-ungalanjathiswa. Xa usenza izibalo kukholelwa ukuba ubunzima lilonke zonke izinto buzinze kwindawo elinikiweyo, oko kukhatshwa ezo zithwala zemikhosi yangaphandle. Ukuba ingxelo nayiphi na inkqubo omzimba amandla, ngokungqinelana ngokupheleleyo kunye nemithetho zolondolozo kwamandla ukubetha ixabiso layo kwiziko ubunzima iya kuba zero. Ukuba ingqalelo yodwa kwiimpembelelo yangaphandle inkqubo, isindululo iziko yayo yobunzima kwenzeka ngesantya esingaguqukiyo rate. Ngako oko, kule meko singakwazi ukuthetha malunga nenkqubo reference inertial.

ingqiqo iziko mass iza kusebenza kwakhona Xa uziyilela izithuthi. Kuyimfuneko ukuba ukuthatha ingqalelo nje izidumbu ezimbini, kwaye inani elikhulu nayo yonke kwakhokelela zifana. Iimpazamo ekubalweni yokunqongophala kwe uzinzo wenqanawa: Xa enye, oko kuya ngokugqithiseleyo antywiliselwa emanzini, esichengeni ukuze ukutshona amaza kakhulu Minor; yaye omnye kakhulu eziphakamileyo ngaphezu komphakamo wolwandle, ukudala ingozi yazibandakanya kwicala layo. Hi ndlela leyi, yiyo lonto into yonke kwibhodi kufuneka endaweni, ngaphandle izibalo: eyona inkulu ezantsi.

Iziko of mass isetyenziswa kuphela malunga imizimba yasezulwini kunye neendlela ukuyila, kodwa ekufundweni "ukuziphatha" amasuntswana sekuba. Ngokomzekelo, abaninzi kubo sizalelwe ngababini (electron-i). Kunye njengokujikeleza original kwaye ngokuxhomekeke kwimithetho yomtsalane / isizathu, ukuba kuthathwa njenge nkqubo kunye iziko oqhelekileyo mass.

Ukuze iinkqubo elula ukubala isikhundla ingongoma kumbindi ubunzima Kulula kakhulu. Kuba oku kuyimfuneko ayilungise imveliso ye ubunzima umzimba esiyua radius nganye, kwaye ixabiso ufumene wahlulwe ubunzima iyonke.
