Linear zog . Linear zog yog kev txav mus los nyob rau hauv ib txoj kab ncaj nraim. Peb lub cev tsim muaj zog uas ua rau angular tsab ntawv tsa suab ntawm peb cov pob qij txha uas tom qab ntawd ua ke ua rau linear zog ntawm peb lub cev. Qhov no yog hu ua general tsab ntawv tsa suab.
Ib yam li ntawd, dab tsi ua rau kev tawm suab?
Linear zog yog qhov tseem ceeb tshaj plaws ntawm txhua tus tsab ntawv tsa suab . Nyob rau txhua hnub, lub zog sab nraud xws li lub ntiajteb txawj nqus thiab kev sib txhuam tuaj yeem ua tau ua rau ib yam khoom los hloov cov kev taw qhia ntawm nws tsab ntawv tsa suab , yog li ntawd nws tsab ntawv tsa suab tsis tuaj yeem piav raws li kab tawm.
Ib sab saum toj no, leej twg nrhiav tau cov lus tsa suab? Galileo Galilei
Hauv qhov no, linear motion txhais li cas?
Linear zog yog tsab ntawv tsa suab raws ib txoj kab ncaj nraim, thiab ua tau yog li no yuav piav txog lej siv tsuas yog ib qho spatial dimension. Cov linear tsab ntawv tsa suab tau ua ob hom: uniform linear zog nrog ceev ceev los yog xoom acceleration; tsis uniform linear zog nrog kev sib hloov ceev los yog tsis xoom acceleration.
Cov piv txwv ntawm linear motion yog dab tsi?
Ib txhia piv txwv ntawm cov lus tsa suab yog ib tug parade ntawm cov tub rog, lub tsheb ciav hlau mus raws txoj kab ncaj nraim thiab ntau yam ntxiv.

Yuav ua li cas koj xam ntsug projectile motion?
Qhov ntsug acceleration muaj tus nqi tas li ntawm rho g, qhov g yog qhov nrawm vim lub ntiajteb txawj nqus, 9.8 meters ib ob-squared ntawm peb ntiaj chaw. Tus qauv thib ob qhia peb tias qhov kawg ntsug tshaj tawm, vy, yog sib npaug rau thawj zaug ntsug tshaj tawm, vo, rho tawm g zaus t
Yuav ua li cas koj xam lub sij hawm nyob rau hauv motion?
Kev daws rau lub sijhawm. Tus nqi ntawm kev hloov ntawm txoj hauj lwm, los yog ceev, yog sib npaug rau qhov kev ncua deb uas tau muab faib los ntawm lub sij hawm. Tosolve rau lub sij hawm, faib qhov kev ncua deb mus los ntawm tus nqi.Piv txwv li, yog Cole tsav nws lub tsheb 45 km ib teev thiab mus atotal ntawm 225 km, ces nws mus rau 225/45 = 5hours
Yuav ua li cas compound yuav tsim yog Aluminium thiab oxygen tau ua ke?
Aluminium tuaj yeem hnov mob nrog cov pa oxygen los tsim cov txhuas oxide (Al_2O_3)
Yuav ua li cas muaj pes tsawg tus tooj liab atoms koj yuav tsum tau kab ntawm ib sab los tsim ib kab 1'm ntev?
Los ntawm kev sib piv, lub ntiaj teb cov pej xeem tsuas yog hais txog 7? 109 neeg. Yog tias koj tuaj yeem ua kab 100,000,000 tooj liab atoms ib sab, lawv yuav tsim ib txoj kab ntev li 1 cm
Yuav ua li cas yuav tsum tshwm sim rau electrons los tsim spectral kab?
Thaum cov electrons txav los ntawm qib siab zog mus rau qis dua, photons raug tso tawm, thiab cov kab hluav taws xob tuaj yeem pom hauv spectrum. Cov kab nqus tau pom thaum electrons nqus photons thiab txav mus rau qib siab zog. Yog hais tias lub atom tau poob ib los yog ntau dua electrons, nws yog hu ua ion thiab hais tias yuav ionized
