Txhua yam khoom txav tau muaj kinetic zog . Thaum ib yam khoom nyob hauv tsab ntawv tsa suab , nws hloov nws txoj hauj lwm los ntawm kev txav mus rau hauv ib qho kev taw qhia: nce, nqis, pem hauv ntej, lossis rov qab. 3. Muaj peev xwm zog yog khaws cia zog . A zog yog lub laub lossis rub uas ua rau ib qho khoom txav mus los, hloov kev taw qhia, hloov ceev, lossis nres.
Ib yam li ntawd, koj tuaj yeem nug, qhov kev txav thiab lub zog 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. quab yuam kuj yuav piav intuitively raws li lub laub los yog rub.
Ib tug kuj yuav nug, dab tsi quab yuam ua rau txav? Kev quab yuam suav nrog lub ntiajteb txawj nqus, kev sib txhuam, thiab siv zog . quab yuam ua hloov nyob rau hauv qhov ceev los yog kev taw qhia ntawm tsab ntawv tsa suab . Cov kev hloov no hu ua acceleration.
Tom qab ntawd, lo lus nug yog, kev txav mus los cuam tshuam lub zog li cas?
Kinetic zog yog tus zog ib yam khoom muaj vim nws tsab ntawv tsa suab . Yog tias peb xav kom ceev ib yam khoom, ces peb yuav tsum siv lub zog. Kev siv lub zog xav tau peb ua ua haujlwm. Tom qab ua haujlwm tiav lawm, zog tau pauv mus rau qhov khoom, thiab qhov khoom yuav yuav tsiv nrog ib tug tshiab tsis tu ncua ceev.
Lub zog thiab kev txav sib cuam tshuam li cas?
Newton txoj cai thib ob ntawm tsab ntawv tsa suab muab kev piav qhia txog tus cwj pwm ntawm cov khoom thaum zog yog siv rau cov khoom. Txoj cai hais tias sab nraud zog ua rau cov khoom kom nrawm, thiab tus nqi ntawm acceleration yog ncaj qha proportional rau lub vas zog thiab inversely proportional rau qhov loj ntawm cov khoom.

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 txawv ntawm daim ntawv cog lus lub zog thiab daim ntawv cog lus dissociation zog?
Qhov sib txawv tseem ceeb ntawm kev sib txuas ntawm lub zog thiab lub zog bonddissociation yog tias lub zog sib txuas yog qhov nruab nrab ntawm lub zog xav tau los rhuav tshem tag nrho cov kev sib txuas ntawm tib ob hom atoms nyob rau hauv ib qho chaw sib txuas whereas daim ntawv cog lus dissociation zog yog tus nqi ntawm cov hluav taws xob xav tau los rhuav tshem ib qho kev sib koom ua ke inhomolysis
Dab tsi yog qhov txawv ntawm lub zog hluav taws xob thiab lub zog sib nqus?
Lub zog hluav taws xob yog tsim los ntawm thiab ua rau, ob qho tib si txav thiab nyob ruaj khov; thaum sib nqus rog yog tsim los ntawm thiab ua rau tsuas yog txav tsub. Hluav taws xob monopoles muaj
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
