Yooj yim harmonic motion yog ib heev tseem ceeb hom oscillation lub sij hawm nyob qhov twg acceleration (α) yog proportional rau lub displacement (x) los ntawm equilibrium, nyob rau hauv cov kev taw qhia ntawm lub equilibrium txoj hauj lwm.
Ntxiv mus, dab tsi yog qhov yooj yim harmonic motion siv rau?
Yooj yim harmonic motion tuaj yeem ua tus qauv lej rau ntau yam kev tawm suab , xws li oscillation ntawm lub caij nplooj ntoos hlav. Yooj yim harmonic motion yog typified los ntawm tsab ntawv tsa suab ntawm ib qho loj ntawm lub caij nplooj ntoos hlav thaum nws raug rau cov linear elastic restoring quab yuam muab los ntawm Hooke txoj cai.
Ib yam li ntawd, kev hloov pauv hauv kev sib haum xeeb yooj yim yog dab tsi? hloov chaw feem ntau yog hais txog kev hloov ntawm txoj hauj lwm thaum ib qho khoom txav los ntawm point A mus rau point B, tab sis feem ntau nyob rau hauv SHM (Kuv xav tias qhov no sawv cev rau yooj yim harmonic motion ), hloov chaw kuj txhais tau tias hloov chaw los ntawm equilibrium txoj hauj lwm uas tsuas yog txoj hauj lwm los yog nyob deb ntawm qhov khoom yog los ntawm nws txoj hauj lwm equilibrium
Hais txog qhov no, puas yooj yim harmonic motion nres?
Nyob rau hauv ib qho kev xav perpetual tsab ntawv tsa suab tshuab nthuav qhia tseeb harmonic zog , tsis muaj dab tsi nres tus tsab ntawv tsa suab tshwj tsis yog ib qho kev quab yuam sab nraud, lossis ib qho khoom siv dampening muab sib npaug ntawm ob qho kawg ntawm cov hlab ntsha ntawm lub tsab ntawv tsa suab . Cov tsab ntawv tsa suab tuaj yeem tuaj so ntawm ob qho tib si ntawm tus ncej, lossis qhov kawg ntawm cov ntsiab lus harmonic zog.
Ib qho piv txwv ntawm kev sib haum xeeb yooj yim yog dab tsi?
Hauv yooj yim harmonic motion , qhov kev tshem tawm ntawm cov khoom yog ib txwm nyob rau hauv lub opposite kev taw qhia ntawm lub restoration quab yuam. Yooj yim harmonic motion yog ib txwm oscillatory. Piv txwv yog cov tsab ntawv tsa suab ntawm tes ntawm ib lub moos, lub tsab ntawv tsa suab ntawm lub log ntawm lub tsheb, thiab lwm yam. Piv txwv yog cov tsab ntawv tsa suab ntawm lub pendulum, tsab ntawv tsa suab ntawm lub caij nplooj ntoos hlav, thiab lwm yam.

Vim li cas peb thiaj li hais txog kev txwv tsis pub muaj kev hais tawm thiab thaum twg peb yuav hais cov kev txwv?
Peb hais txog kev txwv vim nws yuav ua rau qhov sib npaug tsis tau txhais hauv qee qhov txiaj ntsig ntawm x. Qhov kev txwv ntau tshaj plaws rau cov lus qhia muaj nuj nqis yog N / 0. Qhov no txhais tau tias txhua tus lej muab faib los ntawm xoom tsis tau txhais. Piv txwv li, rau txoj haujlwm f(x) = 6/x², thaum koj hloov x = 0, nws yuav ua rau 6/0 uas tsis tau txhais
Qhov kev tsis sib haum xeeb loj sib cais li cas?
Lub Great Unconformity ntawm Powell nyob rau hauv lub Grand Canyon yog ib cheeb tsam unconformity uas cais lub Tonto Group los ntawm lub hauv paus, faulted thiab tilted sedimentary pob zeb ntawm lub Grand Canyon Supergroup thiab vertically foliated metamorphic thiab igneous pob zeb ntawm lub Vishnu Basement pob zeb
Vim li cas nws tseem ceeb uas peb txoj kev nkag siab txog kev tshawb fawb txog kev sib raug zoo txuas ntxiv mus?
Kev nthuav dav thiab kev loj hlob ntawm kev tshawb fawb txog kev sib raug zoo yog qhov tsim nyog vim nws pab txhawb koj txoj kev sib raug zoo thiab kev sib raug zoo nrog cov neeg hauv zej zog. Thaum koj nyob nrog cov neeg koj yuav tsum nkag siab lawv thiab social science pab koj ua li ntawd
Ib qho piv txwv ntawm kev sib haum xeeb yooj yim yog dab tsi?
Nyob rau hauv qhov yooj yim harmonic motion, qhov txav ntawm cov khoom yog ib txwm nyob rau hauv lub opposite kev taw qhia ntawm lub restoration quab yuam. Yooj yim harmonic motion yog ib txwm oscillatory. Piv txwv yog kev txav ntawm tes ntawm lub moos, kev txav ntawm lub log ntawm lub tsheb, thiab lwm yam. Piv txwv yog cov lus tsa suab ntawm lub pendulum, kev txav ntawm lub caij nplooj ntoos hlav, thiab lwm yam
Vim li cas txoj kev kawm txog kev xeeb tub thiab cov yam ntxwv tseem ceeb?
Heredity yog ib qho tseem ceeb rau tag nrho cov kab mob uas muaj sia nyob vim nws txiav txim siab tias yam twg tau dhau los ntawm niam txiv mus rau tus menyuam. Cov yam ntxwv zoo tau dhau mus ntau zaus thiab dhau sijhawm tuaj yeem hloov tau ib hom. Cov kev hloov pauv ntawm qhov zoo tuaj yeem tso cai rau cov kab mob hloov mus rau ib puag ncig tshwj xeeb kom muaj sia nyob zoo dua
