Txoj kev xaiv (d) Kev nrawm ntawm qhov particle yog qhov siab tshaj plaws ntawm txoj haujlwm sib npaugLos ntawm cov lus qhia no, nws pom tseeb tias yog v qhov siab tshaj plaws yog qhov tsawg kawg thiab yog v yog qhov tsawg kawg nkaus., ib max. Raws li nyob rau hauv equilibrium txoj hauj lwm, lub tshaj tawm yog siab tshaj plaws, lub acceleration yuav tsawg kawg nkaus. Yog li kev xaiv (d) tsis raug.
Yuav ua li cas rau qhov particle ua rau SHM?
Cov xwm txheej yog:
- Yuav tsum muaj kev ywj pheej rov ua kom lub zog ua haujlwm ntawm qhov system.
- Lub kaw lus yuav tsum muaj inertia.
- Kev nrawm ntawm lub kaw lus yuav tsum ncaj qha ncaj qha rau nws qhov kev hloov pauv thiab ib txwm qhia rau txoj haujlwm.
Puas particle executing SHM?
A particle executing SHM tau piav qhia los ntawm displacement function x(t)=Acos(ωt+ϕ), Yog tias thawj (t=0) txoj hauj lwm ntawm cov particle yog 1cm, nws qhov pib tshaj tawm yog π cms−1 thiab nws lub kaum sab xis yog πs−1, ces qhov amplitude ntawm nws cov lus tsa suab yog.
Qhov twg yog qhov tseeb txog kev sib haum xeeb yooj yim?
Notes: Tej yam yooj yim harmonic motion yog ib yam tshwj xeeb ntawm lub sij hawm motion, nyob rau hauv uas ib tug particle txav mus rau thiab fro rov qab hais txog ib tug txhais txoj hauj lwm nyob rau hauvib tug restoring quab yuam uas yog ib txwm coj mus rau qhov nruab nrab txoj hauj lwm thiab nws qhov loj ntawm ib qho instant yog ncaj qha proportional rau qhov kev hloov ntawm cov particle los ntawm lub …
Ib nqe lus twg hauv qab no hais txog kab SHM yog cuav?
Kev nrawm yog coj mus rau qhov chaw nruab nrab yog nqe lus raug.
