Zog tsuas tuaj yeem hloov los ntawm ib daim ntawv mus rau lwm qhov. Muaj peev xwm zog yog cov zog nyob rau hauv ib lub cev vim nws txoj hauj lwm. Thaum kinetic zog yog cov zog nyob rau hauv lub cev vim nws txoj kev txav. Cov mis rau muaj peev xwm zog yog mgh, qhov twg m sawv rau qhov loj, g sawv rau gravitational acceleration thiab h sawv rau qhov siab.
Xav txog qhov no, dab tsi yog qhov yooj yim txhais ntawm kinetic zog?
Kinetic zog yog cov zog ntawm cov lus tsa suab, pom tau raws li qhov txav ntawm ib qho khoom, particle, los yog txheej ntawm cov khoom. Txhua yam khoom hauv kev txav yog siv kinetic zog : ib tug neeg taug kev, pov pob baseball, ib tug crumb poob los ntawm lub rooj, thiab ib tug nqi particle nyob rau hauv ib tug hluav taws xob teb yog tag nrho cov piv txwv ntawm kinetic zog tom haujlwm.
Tom qab ntawd, lo lus nug yog, koj txhais li cas los ntawm kinetic zog? Nyob rau hauv physics, lub kinetic zog (KE) ntawm qhov khoom yog qhov zog uas nws muaj vim nws txoj kev txav. Nws txhais tau hais tias yog txoj haujlwm xav tau los ua kom lub cev ntawm ib qho khoom loj los ntawm so mus rau nws qhov kev tshaj tawm. Tau txais qhov no zog thaum nws acceleration, lub cev tswj qhov no kinetic zog tshwj tsis yog nws qhov nrawm hloov.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog lub zog kinetic thiab lub zog muaj peev xwm nrog piv txwv?
Kinetic zog yog txuam nrog ib yam khoom nrog ib tug loj txav ntawm ib tug ceev thaum muaj peev xwm zog yog txuam nrog ib qho khoom nyob ruaj ruaj nrog ib qho loj ntawm qhov siab tshaj hauv av. Ib piv txwv ntawm ib yam khoom nrog kinetic zog yuav yog ib lub tsheb tsav raws txoj kev loj ntawm 100km/h.
4 kinetic zog piv txwv yog dab tsi?
13 Piv txwv ntawm Kinetic Zog hauv Lub Neej Txhua Hnub
- Tsav Tsheb. Cov tsheb txav muaj qee lub zog kinetic.
- Bullet Los ntawm Phom. Ib lub mos txwv raug rho tawm ntawm rab phom muaj lub zog kinetic siab heev, thiab, yog li, nws tuaj yeem nkag tau yooj yim rau txhua yam khoom.
- Flying Airplane.
- Taug kev & Khiav.
- Kev caij tsheb kauj vab.
- Rollercoasters.
- Cricket Pob.
- Skateboarding.

Lub zog thiab lub zog ua haujlwm yog dab tsi?
WORK = W = Fd. Vim tias lub zog yog lub peev xwm ua haujlwm, peb ntsuas lub zog thiab ua haujlwm hauv tib chav (N * m lossis joules). POWER (P) yog tus nqi ntawm lub zog tsim (lossis nqus) lub sijhawm: P = E / t. Fais fab lub SI unit ntawm kev ntsuas yog Watt, sawv cev rau tiam los yog nqus ntawm lub zog ntawm tus nqi ntawm 1 Joule / sec
Dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm kinetic thiab lub zog muaj peev xwm?
Lub Zog Muaj Peev Xwm yog lub zog khaws cia hauv ib qho khoom lossis qhov system vim nws txoj haujlwm lossis kev teeb tsa. Kinetic zog ntawm ib yam khoom yog txheeb ze rau lwm yam khoom txav thiab nyob ruaj ruaj hauv nws qhov chaw tam sim ntawd
Dab tsi yog kev sib raug zoo ntawm gravitational muaj peev xwm zog thiab kinetic zog?
Thaum ib yam khoom ntog, nws lub peev xwm gravitational hloov mus rau kinetic zog. Koj tuaj yeem siv qhov kev sib raug zoo no los xam qhov ceev ntawm qhov khoom qhovntsej thiaj tsis mob. Gravitational muaj peev xwm zog rau ib pawg m ntawm qhov siab h nyob ze ntawm lub ntiaj teb yog mgh ntau tshaj li lub zog muaj peev xwm yuav nyob rau qhov siab 0
Dab tsi yog qhov txawv ntawm lub zog siv zog thiab lub zog thauj khoom?
Raws li nrog cov dav hlau inclined, cov khoom yuav tsum tau txav mus los yog lub zog muaj zog los yog thauj khoom thiab kev siv zog yog lub zog muab tso rau hauv kev txav mus los ntawm lwm qhov kawg ntawm lub fulcrum
Dab tsi yog cov qauv ntawm lub zog nyob rau hauv lub peev xwm thiab lub zog kinetic?
Lub zog muaj peev xwm yog khaws cia lub zog thiab lub zog ntawm txoj haujlwm - lub zog gravitational. Muaj ntau hom kev muaj peev xwm muaj zog. Kinetic zog yog kev txav - ntawm nthwv dej, electrons, atoms, molecules, tshuaj, thiab khoom. Chemical Zog yog lub zog khaws cia hauv cov khoom sib txuas ntawm atoms thiab molecules
