Tsab ntawv tsa suab tshwm sim thaum ib yam khoom hloov nws txoj hauj lwm nrog lub sij hawm. Thaum ib lub cev npog qhov sib npaug ntawm qhov sib npaug ntawm lub sijhawm, nws txav mus rau qhov sib npaug tsab ntawv tsa suab . Tsis-uniforms Tsab ntawv tsa suab . Thaum lub cev npog qhov tsis sib npaug ntawm qhov sib npaug ntawm lub sijhawm. nws mus nrog tsis-uniform tsab ntawv tsa suab.
Tom qab ntawd, ib tug kuj yuav nug, tsab ntawv tsa suab piav qhia yog dab tsi?
Hauv physics, tsab ntawv tsa suab yog qhov kev hloov ntawm txoj haujlwm ntawm ib qho khoom dhau sijhawm. Tsab ntawv tsa suab yog lej piav qhia nyob rau hauv cov nqe lus ntawm kev hloov chaw, nyob deb, tshaj tawm, acceleration, ceev, thiab lub sij hawm. Yog li, lub sij hawm tsab ntawv tsa suab , feem ntau, qhia txog kev hloov pauv tsis tu ncua ntawm txoj haujlwm lossis kev teeb tsa ntawm lub cev hauv qhov chaw.
Ib yam li ntawd, qhov ceev hauv physics chav kawm 9 yog dab tsi? Ceev ceev : Ceev ceev yog cov ceev ntawm ib yam khoom txav mus rau qhov tseeb. SI unit of ceev kuj yog ' meter ' ib ob. Ceev ceev yog vector kom muaj nuj nqis; nws muaj ob qhov loj thiab kev coj.
Ib tug kuj yuav nug, dab tsi yog hom kev txav?
Nyob rau hauv lub ntiaj teb no ntawm mechanics, muaj plaub theem pib hom kev txav . Cov plaub no yog rotary, oscillating, linear thiab reciprocating. Txhua tus txav hauv me ntsis txawv txoj kev thiab txhua tus hom ntawm tiav siv txawv mechanical txhais tau tias pab peb nkag siab cov kab tsab ntawv tsa suab thiab tsab ntawv tsa suab tswj.
Lub zog txav yog dab tsi?
Hauv physics, a zog yog ib qho kev sib cuam tshuam uas, thaum unopposed, yuav hloov lub tsab ntawv tsa suab ntawm ib yam khoom. A zog tuaj yeem ua rau ib qho khoom nrog huab hwm coj hloov nws qhov nrawm (uas suav nrog pib txav ntawm lub xeev so), piv txwv li, kom nrawm. A zog muaj ob qhov loj thiab kev taw qhia, ua rau nws muaj vector kom muaj nuj nqis.

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
Dab tsi yog tus qauv ntawm qhov projectile motion?
Ib yam khoom uas tso rau hauv qhov projectile yuav muaj lub kaum sab xis pib qhov twg los ntawm 0 txog 90 degrees. Qhov siab tshaj plaws ntawm ib yam khoom, muab lub kaum sab xis pib thiab pib tshaj tawm yog pom nrog: h = v2isin2θi2g h = v i 2 sin 2 ? θ kuv 2g
