The default jiki makanikai da aka soma a matsayin abu batu, sai dai in ba haka ba a kayyade.

motsi line nuna a sarari - a yanayin motsi. Mene ne wannan? Wannan mas'ala ta "yanayin", kamar yadda aka ayyana ta gargajiya makanikai, ya shafi tarin dukan arziki, consistently shagaltar da wani abu batu a sarari.

Don sanin ko matsayi, wanda ya mamaye sarari a cikin taro batu a wani musamman lokacin, yin amfani da manufar da radius vector ko tsara tsarin. A dabi'u na tsarawa x, y, z bayyana maki na wani mikakke tsari dangi zuwa Game da gatura. Formula canje-canje na wadannan tsarawa (ko da matsayi na radius vector), kuma suna da dabara wanda aka ƙaddara ta hanyar motsi.

Tun da motsi ba kawai a sarari amma kuma a lokaci, da uku bangaren na reference tsarin - domin lokaci-aunawa na'urar (Agogon awon gudu ko). A hade da tsara tsarin da farawa (frame jiki) suka samar da ake so "sa" ya bayyana kudirin na mu kayan batu.

Bari motsi hanya ne wani baka da farkon a wata aya M1 wanda kula x1, Y1 da Z1, da kuma karshen batu a M2 (kula x2, Y2, Z2). A nesa da cewa abu ya wuce ta batu na ta yanayin (baka tsawon | M1M2 |) za a kira da tsawon da madaidaiciya. Wannan shi ne wani scalar darajar.

Idan muka zana daga aya don nuna M1 M2 directed kashi (vector) r, to, shi za a kira da motsi na da wani abu aya. Wannan mas'ala - ba m da ra'ayi na hanyar. The hanyar da dabba ba a kanta maki daidaita kawai a yanayin saukan motsi a cikin wani madaidaiciya line.

A kinematic dokar motsi (ko wani hanya ne na tabbatar da dalilin da ta tsarawa a kowane lokaci) ne a aiki na lokaci da kuma iya ɗaukar kamannin analytical aiki tsara ko radius vector daga m t, denoting lokacin motsi.
