General Planar motion tso cai rau ib txhij rotational thiab translational tsab ntawv tsa suab hauv 2-D dav hlau . Cov tsab ntawv tsa suab ntawm lub cev nruj tej zaum yuav piav raws li ib qho yooj yim superposition ntawm lub cev txhais lus thiab kev sib hloov raws li qhia hauv daim duab hauv qab no.
Tsis tas li ntawd, lub ntsiab lus ntawm kev txav txav yog dab tsi?
Plane Motion . tus tsab ntawv tsa suab ntawm lub cev nruj xws li tias tag nrho nws cov ntsiab lus txav mus rau qhov sib npaug rau qee qhov ruaj dav hlau . Xws li tsab ntawv tsa suab yog tsim los ntawm translational tsab ntawv tsa suab ua ke nrog ib tug arbitrarily xaiv ncej nyob ib ncig ntawm uas rotational tsab ntawv tsa suab tshwm sim.
Qhov thib ob, lub dav hlau dav dav yog dab tsi? dav dav dav Cov lus tsa suab tshwm sim thaum lub cev tsis muaj zog tau txais kev txhais lus thiab kev sib hloov ib txhij. Koj tuaj yeem txheeb xyuas qhov teeb meem zoo li no los ntawm kev siv qhov kev tshuaj ntsuam xyuas qhov tseeb lossis kev txheeb xyuas qhov txheeb ze.
Tib neeg kuj nug tias, lub cev planar yog dab tsi?
Ntawm no yog ib phau ntawv sau rau ntawm kev npaj dynamics ntawm nruj cev . Thaum peb hais kev npaj dynamics, peb tab tom xa mus rau dynamics ntawm cev uas tsuas tuaj yeem tig txog ib qho axis (perpendicular rau "dav hlau"). Kinetic zog ntawm ib tug nruj lub cev (derivation tuaj). Angular momentum ntawm ib tug nruj lub cev (derivation tuaj).
Dab tsi yog kev taw qhia dav dav hauv kev ua si nawv?
Cov lus tsa suab yog ib qho kev sib txuas ntawm linear thiab rotary kev tawm suab . Cov lus tsa suab yog hom ntau tshaj plaws kev ua si hauv kev ua si nawv thiab kev tawm dag zog lub cev. Hauv qhov no, lub cev txav mus rau hauv linear tsab ntawv tsa suab raws li qhov tshwm sim ntawm rotary kev tawm suab ntawm tus kheej ntu ntawm extremities. Caij tsheb kauj vab yog lwm qhov piv txwv ntawm kev taw qhia dav dav.

Dab tsi yog qhov orbital motion ntawm lub galaxy?
Yog lawm, Lub Hnub - qhov tseeb, peb lub hnub ci tag nrho - orbits nyob ib ncig ntawm qhov chaw ntawm Milky Way Galaxy. Peb tab tom txav ntawm qhov nrawm nrawm ntawm 828,000 km / teev. Tab sis txawm tias tus nqi siab ntawd, nws tseem yuav siv sij hawm peb txog 230 lab xyoo los ua ib qho kev ua tiav nyob ib ncig ntawm Milky Way! Milky Way yog lub kauv galaxy
Vertical motion nyob rau hauv physics yog dab tsi?
Vertical Motion. Vertical motion yog hu ua qhov txav ntawm qhov khoom tawm tsam qhov rub tawm. Nws yog cov lus tsa suab uas yog perpendicular rau qhov ncaj los yog tiaj tus. Qhov ceev ntawm lub kheej kheej nyob rau hauv lub upward motion yog sib npaug rau qhov ceev ntawm lub downward motion
Ib qho piv txwv ntawm Brownian motion yog dab tsi?
Brownian Motion Piv Txwv Feem ntau cov piv txwv ntawm Brownian motion yog thauj cov txheej txheem uas cuam tshuam los ntawm cov dej ntws loj, tseem muaj cov pedesis. Piv txwv li: Kev txav ntawm paj paj noob qoob rau ntawm cov dej tseem. Kev txav ntawm plua plav motes hauv chav tsev (txawm hais tias feem ntau cuam tshuam los ntawm huab cua tam sim no)
Ib qho piv txwv ntawm Newton's Second Law of Motion yog dab tsi?
4. Newton's 2nd Law ? Txoj cai thib ob ntawm kev txav mus los hais tias kev nrawm yog tsim thaum lub zog tsis sib npaug ua rau ntawm ib qho khoom (ntau). Piv txwv ntawm Newton's 2nd Law? Yog tias koj siv tib lub zog los thawb lub tsheb thiab thawb lub tsheb, lub tsheb yuav muaj kev nrawm dua li lub tsheb thauj khoom, vim tias lub tsheb muaj qhov hnyav dua
Planar txaj yog dab tsi?
Cov feem ntau piav qhia yog tabular cross-bedding thiab trough cross-beddding. Tabular cross-bedding, los yog planar txaj muaj cov ntoo khaub lig-bedded units uas dav dav kab rov tav txheeb ze rau cov txheej tuab thiab uas muaj qhov tseem ceeb ntawm cov npoo npoo
