Yooj yim harmonic motion . Los ntawm Wikipedia, dawb encyclopedia. Hauv mechanics thiab physics, yooj yim harmonic motion yog ib hom tshwj xeeb ntawm lub caij nyoog tsab ntawv tsa suab los yog oscillation qhov twg lub restoring quab yuam yog ncaj qha proportional rau lub displacement thiab ua nyob rau hauv cov kev taw qhia opposite rau ntawm qhov chaw.

Hauv qhov no, koj txhais li cas los ntawm kev sib haum xeeb yooj yim?

Txhais ntawm yooj yim harmonic motion :ib harmonic zog ntawm tas li amplitude nyob rau hauv uas lub acceleration yog proportional thiab oppositely coj mus rau qhov chaw ntawm lub cev los ntawm ib tug equilibrium: qhov projection ntawm ib txoj kab uas hla ntawm ib tug taw tes nyob rau hauv uniform tsab ntawv tsa suab ncig ib ncig.

Ib tug kuj yuav nug, dab tsi yog kev hloov pauv hauv kev sib haum xeeb yooj yim? 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

Ib yam li ib tug yuav nug, vim li cas nws thiaj hu ua yooj yim harmonic motion?

Yooj Yim Harmonic Motion ( S. H. M .) Thaum ib yam khoom txav mus rau thiab fro raws ib kab, lub tsab ntawv tsa suab yog hu ua yooj yim harmonic motion . Thaum peb viav vias, nws txav mus rau thiab fro raws tib txoj kab. Cov no yog hu ua oscillations. Oscillations ntawm pendulum yog ib qho piv txwv ntawm yooj yim harmonic motion.

K yog dab tsi nyob rau hauv yooj yim harmonic motion?

Graph of displacement tiv thaiv lub sijhawm hauv yooj yim harmonic motion . qhov twg F yog lub zog, x yog hloov chaw, thiab k yog qhov zoo tas li. Qhov no zoo ib yam li Hooke Txoj Cai, uas hais tias lub zog F ntawm ib qho khoom ntawm qhov kawg ntawm lub caij nplooj ntoos hlav sib npaug -kx, qhov twg k yog lub caij nplooj ntoos hlav tsis tu ncua.

Dab tsi yog qhov txawv ntawm osmosis diffusion thiab yooj yim diffusion?

Osmosis kuj tshwm sim thaum dej txav ntawm ib lub cell mus rau lwm qhov. Kev yooj yim diffusion ntawm qhov tod tes tshwm sim thaum qhov nruab nrab nyob ib puag ncig ntawm lub cell yog nyob rau hauv siab concentration ntawm ions los yog molecules tshaj qhov chaw nyob rau hauv lub cell. Cov molecules txav los ntawm ib puag ncig nruab nrab mus rau hauv lub cell vim diffusion gradient

Daim ntawv yooj yim tshaj plaws rau 6 20 yog dab tsi?

Simplify 6/20 rau daim ntawv yooj yim tshaj plaws. Online yooj yim lub laij lej feem ntau kom txo tau 6/20 rau cov nqe lus qis tshaj sai thiab yooj yim. 6/20 Cov Lus Teb Yooj Yim: 6/20 = 3/10

Dab tsi yog qhov yooj yim ncaj saw alkane?

Alkanes. Ib qho alkane yog hydrocarbon nyob rau hauv uas tsuas muaj ib qho kev sib cog lus xwb. Qhov yooj yimstalkane yog methane, nrog cov mis molecular CH4. Cov pa roj carbonis lub hauv paus atom thiab ua rau plaub ib qho kev sib cog lus rau hydrogen atoms

Dab tsi yog organelle yooj yim txhais?

Organelle. Ib qho organelle yog ib feem me me ntawm cov cell uas muaj cov haujlwm tshwj xeeb lossis txoj haujlwm. Lub nucleus nws tus kheej yog ib qho organelle. Organelle yog ib qho me me ntawm lub cev, los ntawm lub tswv yim hais tias ib yam li lub cev txhawb nqa lub cev, organelles txhawb nqa tus kheej ntawm tes
