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.
