SISTEMAI SARHISOB

SISTEMAI SARHISOB dar mekhanika, majmui sistemai koordinataho ,va soathoi vobasta ba jismest, ki nisbat ba on harakat yo muvozinati yagon jism ë nuqtahoi materiali omukhta meshavad. Har guna harakati jism nisbi meboshad va binobar on harakati onhoro nisbat ba yagon jismi digar (jismi sarhisob) yo sistamai jismho boyad muayyan kard.

Harakati matematikii jism (ë nuqtai materiali) nnsbat ba Sistemai sarhisobi muntakhab tavassuti muodilahoe ifoda meshavad, ki vobastagii tagyiryobii koordinataho va vaqti guzashtaro dar in Sistemai sarhisob ifoda menamoyad.

Masalan dar koordivatahoi dekarti kh, u, z harakati nuqta bo yorii muodilaho ba istiloh muodilahoi harakat muayyan khohad shud (nigared niz Kinematika). Intikhobi Sistemai sarhisob ba maqsadi tadqiqot vobasta ast. Dar mavridi tadqiqothoi kinematiki hamai sistemahoi sarhisob barobarhuquqand.

Dar halli masalahoi dinamiki sistemai sarhisobi inersiali istifoda meshavad, ki dar on muodilai differensialii harakat shakli nisbatan sodda dorad.
