Oscillatory Motion vs Periodic Motion
Oscillatory thiab ntu ntu ntu muaj ntau heev hauv cov xwm txheej thiab yog li ntawd, tseem ceeb heev hauv ntau lub tshuab. Oscillatory motions yog cov lus tsa suab uas muaj qhov sib npaug. Periodic motions yog cov lus tsa suab uas rov ua nws tus kheej hauv lub sijhawm. Ob hom kev txav no tau siv dav hauv thaj chaw xws li astronomy, cosmology, satellite technology, moos tsim, planetary motion, tsheb engineering, machinery thiab ntau yam. Nws yog ib qho tseem ceeb kom muaj kev nkag siab zoo ntawm cov lus tsa suab no thiaj li ua tau zoo hauv cov haujlwm no. Hauv tsab xov xwm no, peb yuav tham txog dab tsi oscillatory motions thiab periodic motions yog, lawv cov ntsiab lus, qhov zoo sib xws ntawm oscillatory motion thiab periodic motion, lawv daim ntawv thov thiab thaum kawg qhov txawv ntawm oscillatory motion thiab periodic motion.
Nyob rau lub sijhawm
Cov lus tsa suab ib ntus txhais tau tias yog txhua yam kev tawm suab uas rov ua nws tus kheej dhau sijhawm. Periodic motions muaj ntau nyob rau hauv cov xwm. Cov lus tsa suab xws li cov lus tsa suab, lub suab ntawm lub hli nyob ib ncig ntawm lub ntiaj teb, cov lus tsa suab ntawm orbital satellites, cov lus tsa suab ntawm cov hniav ntawm cov kiv cua, kev sib hloov ntawm lub cav yog qee qhov piv txwv rau cov lus tsa suab. Cov lus tsa suab ib ntus tuaj yeem muab faib ua ob pawg loj. Ua ntej ib qho yog natural periodic motions, uas tshwm sim nyob rau hauv qhov tsis muaj lwm yam quab yuam; hom thib ob yog cov khoom tsim los yog tib neeg ua raws li cov lus tsa suab. Cov lus tsa suab no yog yuam kom ncua sij hawm xws li lub cav diesel. Cov lus tsa suab ib ntus tuaj yeem tshwm sim hauv txoj hauv kev tsis tu ncua xws li lub voj voog, ellipses lossis hauv txoj kev tsis sib xws, uas tsis tuaj yeem txhais tau yooj yim. Feem ntau ntawm cov lus tsa suab uas tshwm sim nyob rau hauv txoj kev tsis sib xws yog yuam kev ua ntu zus.
Oscillatory Motion
Oscillatory motions yog ib hom kev txav mus los. Ib qho kev taw qhia oscillatory feem ntau txhais tau tias yog kev hloov pauv ntau zaus dhau sijhawm. Cov lus tsa suab oscillatory tuaj yeem tshwm sim dhau qhov nruab nrab qhov sib npaug lossis nruab nrab ntawm ob lub xeev. Lub pendulum yog ib qho piv txwv zoo rau kev ua haujlwm oscillatory. Cov lus tsa suab oscillatory feem ntau yog sinusoidal. Ib qho alternating tam sim no kuj yog ib qho piv txwv zoo rau oscillatory motion. Nyob rau hauv qhov yooj yim pendulum, lub bob oscillates tshaj qhov nruab nrab equilibrium point. Nyob rau hauv ib qho alternating tam sim no, cov electrons oscillate nyob rau hauv lub kaw Circuit Court nyob rau hauv ib tug equilibrium point. Muaj peb hom oscillatory motions. Thawj hom yog cov lus tsa suab oscillatory un-damped uas lub zog sab hauv ntawm cov lus tsa suab oscillatory tseem nyob tas li. Qhov thib ob hom oscillatory motions yog damped oscillatory motions. Nyob rau hauv cov ntaub ntawv ntawm damped oscillatory motions, lub zog sab hauv ntawm lub oscillatory motion txo lub sij hawm. Qhov thib peb yog qhov yuam kev oscillatory motions. Hauv kev quab yuam oscillatory motions, lub zog yog siv rau ntawm lub pendulum nyob rau hauv ib lub sij hawm hloov mus rau lub pendulum.
Qhov txawv ntawm Oscillatory Motion thiab Periodic Motion yog dab tsi?
• Oscillatory motions yog ib hom kev txav mus los.
• Oscillatory motions raug txhais tau zoo rau cov oscillations damped, yooj yim harmonic oscillations, thiab rau yuam oscillations. Cov lus tsa suab ib ntus feem ntau tsis txhais tau zoo.
• Cov lus tsa suab ib ntus muaj ntau nyob rau hauv qhov xwm txheej, tab sis cov lus tsa suab oscillatory yog me ntsis tsawg.
• Oscillatory motions tuaj yeem sawv cev rau lwm hom kev txav mus los.
