Uniform motsi da kuma ta siffofin

Daga cikin iri-iri ƙungiyoyi, irin wannan karatu sashe na kimiyyar lissafi, a matsayin kinematics, akwai irin wanda jiki ga kowane siddan zaba daidai jinkiri na lokaci ya wuce daidai tsawon segments na hanyar. Yana - uniform motsi. An misali ne da motsi na da wani skater a tsakiyar nesa jirgin kasa, ko a kan wani lebur mike.

Rubuce, jiki zai iya matsawa tare da wani hanya, ciki har da mai lankwasa. A wannan yanayin, akwai manufar hanyar - don haka da nesa tafiya ta jiki tare da madaidaiciya. Path - a scalar yawa, kuma ba za a gauraye da motsi. A karshen lokaci suturta tazara tsakanin farawa kuma da karshe hanya wadda ne a curvilinear motsi da gangan ba tare da daidaita yanayin. Travel - vector yawa da ciwon lamba darajar daidaita da tsayin daga cikin vector.

Tambaya taso - a wasu lokuta muna magana ne game da uniform motsi? Yana za a yi la'akari da uniform motsi, kamar wani carousel a cikin da'irar da wannan gudun? A'a, domin a irin wannan tashin gudu vector ta sauya shugabanci kowane biyu.

Wani misali - da mota da aka tafiya a mike layin a cikin wannan gudun. Irin wannan motsi, za a dauke shi a uniform, yayin da mota ba zai mirgine up da kuma injin gwada sauri shi ne guda lambar. Babu shakka, uniform motsi ko da yaushe yakan faru a cikin wani madaidaiciya line, da gudu vector aka bai canja ba. A hanya da kuma motsi a cikin wannan hali zai zama iri ɗaya.

Uniform motsi - motsi a cikin wani madaidaiciya line yanayin at akai gudun, cikinsa da tsawon na hanyar traversed jinkiri ga wani yau da kullum lokaci jinkiri ne m. A musamman idan akwai uniform motsi za a iya dauke a matsayin jihar da hutawa, a lokacin da gudun da kuma nesa tafiya ne daidai da sifili.

Speed ne ingantaccen halayyar uniform motsi. Babu shakka, daban-daban abubuwa ne daya da kuma guda hanyar a wani lokaci dabam (tafiya a ƙasa da kuma mota). Halayen rufe gaba ɗaya dabba ba a kanta jiki ga tsawon lokacin da hanya da aka wuce, da ake kira da gudun motsi.

Saboda haka, dabara ta kwatanta uniform motsi, shi ne kamar haka:

V = S / t; inda V - gudu (a vector yawa).

S - ko motsi hanya.

t - lokaci.

Sanin gudun, wanda shi ne m, za mu iya lissafta da hanyar traversed da jiki ga kowane sabani lokaci.

Wani lokacin kuskure gauraye a ko'ina da kuma gaba ɗaya ya kara motsi. Wannan shi ne wani mabanbanta ra'ayi. Gaba ɗaya kara motsi - daya embodiment m motsi (.. Watau cewa a wadda gudun ba m), wanda yana da wani muhimmanci alama - gudun a irin wannan wani motsi dabam domin wannan jinkiri a kan wannan darajar. Wannan darajar ne daidaita da zumunta gudu bambancin da tsawon lokaci a lokacin da gudun canji ne ake kira hanzari. Wannan lambar nuna adadin da wanda gudun ne ta ƙara ko rage da naúrar na lokaci na iya zama manyan (sai ka ce cewa jiki ne hanzari samun ko rasa gudun) ko negligible lokacin da abu accelerates ko slows saukar more smoothly.

Hanzari, kazalika da gudu ne vector jiki yawa. Hanzari vector a cikin shugabanci ko da yaushe ya zo daidai da gudu vector. Wani misali na gaba ɗaya kara motsi shi ne yanayin da free fall na magana, cikinsa da fadowa gudun (gudun janye abu duniya ta surface) dabam a naúrar na lokaci ta wani daraja kira da hanzari na free fall.

Uniform motsi iya rubuce a kyan gani, kamar yadda na musamman hali na gaba ɗaya kara. Babu shakka, tun gudun a cikin irin wannan tashin ba ya canja, cikin hanzari, ko deceleration ba ya faruwa, sabili da haka, cikin hanzari darajar a lokacin da uniform motsi ne ko da yaushe daidaita da sifili.
