MOMENT

MOMENT (lot. momentum — quvvai tahrika, takon, ibtidoi harakat, az moveo — harakat mediham), mafhumi matematikiest, ki dar mekhanika va nazariyai ehtimoliyat maqomi muhim dorad. Agar sistemai nuqtahoi materialii massaashon t., mj, ,..(p»# > 0) dar khati rost joy girifta boshad va abssissaho nisbat ba yagon nuqtai sarhisob O muvofiqan ba Kh|, kh2, … barobar boshand, jami momenti tartibi k-umi in sistema nisbat ba nuqtai o menomand. Mombasai tartibi yakum dar mekhanika Mombasai statiki, Mombasai tartibi duyum momenti inersiya nomida meshavad. Agar dar ifodai Mombasa hamai abssissaho bo qimathoi mutlaqashon girifta shavand, Mombasai mutlaq hosil meshavad. Nuqtai abssissaash (2*^) (Um*) markazi massahoi sistemai dodashuda nom dorad. Mombasai nisbat ba markaz hisob kardashudaro Mombasai markazi menomand. Baroi har guna sistema Mombasai markazii tartibi yakum ba safr barobar ast.

Dar nazariyai ehtimoliyat ba sifati abssissaho qimathoi gunoguni imkonpaziri buzurgii tasodufi va ba sifati massa ehtimoliyathoi muvofiqi az qimathoro qabul mekunand. Mombasai tartibi yakum, ki dar in holat hamesha abssissai markazi massa meboshad (zero massai purra ba 1 barobar ast), intizoriyati materikii in buzurgii tasodufi va Mombasai markazii tartabi duyum disversiyai on nomida meshavad.
