Classical mechanics yog ib ceg ntawm physics uas cuam tshuam nrog kev txav ntawm lub cev raws li Isaac Newton's lawsof mechanics . Classical mechanics piav qhia txog kev txav ntawm qhov taw tes pawg (cov khoom me me infinitesimally) thiab ntawm rigidbodies (cov khoom loj uas tig tab sis tsis tuaj yeem hloov pauv).
Hais txog qhov no, dab tsi yog classical mechanics thiab nws hom?
Classical mechanics tau ib txwm muab faib ua peb ceg tseem ceeb: Statics, tus kawm txog equilibriumand nws kev cuam tshuam rau lub zog. Dynamics , tus kawm txog kev txav thiab nws kev cuam tshuam rau lub zog.
Tsis tas li ntawd, dab tsi yog qhov ua tsis tiav ntawm classical mechanics? Cov tsis ua hauj lwm ntawm classical physics los piav qhia txog lub cev hluav taws xob, cov nyhuv photoelectric, thiab hydrogenatom kawg rhuav tshem cov hauv paus ntawm classicalphysics . Max Planck, Albert Einstein, Niels Bohr, thiab Louis deBroglie tau txais kev tshoov siab txog kev ua haujlwm zoo li cas.
Ib yam li ntawd, lub ntsiab txhais ntawm classical physics yog dab tsi?
classical physics . Physics uas tsis siv quantum mechanics los yog txoj kev xav ntawm kev sib raug zoo. Classical mechanics hais txog cov classical physics ntawm lub cev thiab lub zog, tshwj xeeb tshaj yog Newton txoj cai ntawm kev txav thiab cov ntsiab lus ntawm mechanics raws li lawv. Sib piv quantum mechanics.
Dab tsi yog qhov txhais ntawm mechanics hauv physics?
Mechanics (GreekΜηχανική) yog thaj chaw ntawm kev tshawb fawb txog kev coj tus cwj pwm ntawm lub cev thaum raug quab yuam los yog tsiv, thiab cov teebmeem tom qab ntawm lub cev ntawm lawv ib puag ncig. Nws kuj tuaj yeem ua tau txhais raws li abranch ntawm science uas cuam tshuam nrog kev txav ntawm thiab quab yuam onobjects.

Dab tsi yog lub ntsiab lus ntawm ib pab pawg ntawm cov lus teev sijhawm?
Nyob rau hauv chemistry, ib pab pawg (tseem hu ua tsev neeg) yog ib kem ntawm cov ntsiab lus nyob rau hauv lub sij hawm lub sij hawm ntawm cov tshuaj. Muaj 18 pawg lej nyob rau hauv daim ntawv teev sijhawm; cov kab f-block (nruab nrab ntawm pawg 3 thiab 4) tsis suav nrog
Lub ntsiab lus ntawm lub hauv paus lo lus meter nyob rau hauv lo lus tus pas ntsuas kub yog dab tsi?
Lub hauv paus chiv keeb ntawm lo lus 'Thermometer' Qhov thib ob ntawm lo lus, 'meter', los ntawm Fabkis -mètre (uas muaj nws cov hauv paus hauv lub post-classical Latin: -meter, -metrumand lub ancient Greek, -Μέτρο ν, lossis metron, uas txhais tau tias ntsuas qee yam, xws li qhov ntev, qhov hnyav, lossis dav)
Dab tsi yog qhov txawv ntawm classical mechanics thiab quantum mechanics?
Nyob rau hauv luv luv, lub ntsiab sib txawv ntawm quantum thiab classical physics yog qhov txawv ntawm ib tug rampand ib staircase. Nyob rau hauv classical mechanics, cov xwm txheej (feem ntau) yog tas mus li, uas yog hais tias lawv txav mus rau hauv tus qauv, muaj kev sib haum xeeb thiab ua tau zoo. Qhov projectile motion yog ib qho piv txwv zoo ntawm classical mechanics
Dab tsi yog lub ntsiab lus ntawm kev hloov pauv lom neeg hauv cov ntsiab lus ntawm allele zaus?
Microevolution, los yog evolution ntawm ib tug me me, yog txhais raws li ib tug kev hloov nyob rau hauv lub zaus ntawm noob variants, alleles, nyob rau hauv ib tug pej xeem ntau tiam. Lub teb ntawm biology uas kawm txog allele frequencies nyob rau hauv cov pejxeem thiab yuav ua li cas lawv hloov lub sij hawm yog hu ua pej xeem noob caj noob ces
Lub npe ntawm tag nrho cov ntsiab lus ntawm lub sij hawm lub rooj yog dab tsi?
Tus lej xov tooj yog nws tus lej atomic, uas yog tus naj npawb ntawm protons hauv txhua qhov ntawm nws cov atoms. H - Hydrogen. Nws - Helium. Lithium roj teeb. Ua - Beryllium. B - Boron. C - Cov pa roj carbon. N - Nitrogen. O - Cov pa
