kinetic zog yog yam tsawg kawg, lub zog muaj peev xwm yog siab tshaj. ob qho tib si kinetic thiab muaj peev xwm muaj zog yog qhov siab tshaj plaws. ob qho tib si kinetic thiab muaj peev xwm muaj zog yog qhov tsawg kawg nkaus. …

Txoj haujlwm txhais li cas ntawm qhov yooj yim harmonic oscillator?

M, kinetic zog ntawm particle ntawm txhua qhov P yog. Kinetic zog=21mω2(a2−x2) Muaj peev xwm zog=(21mω2x2) qhov twg a yog amplitude ntawm particle thiab x yog qhov deb ntawm qhov chaw nruab nrab. Yog li, ntawm txoj haujlwm txhais tau tias, x=0.

Txoj haujlwm txhais li cas hauv kev sib haum xeeb yooj yim?

Yuav muaj lub zog rov qab los ntawm txoj haujlwm sib npaug (lossis) txoj haujlwm txhais tau tias. Nyob rau hauv ib qho kev txav oscillatory, lub zog net ntawm cov khoom yog xoom ntawm qhov chaw nruab nrab. Txoj hauj lwm nruab nrab yog txoj haujlwm ruaj khov.

Ntawm txoj haujlwm twg yog qhov nrawm tshaj plaws rau qhov yooj yim harmonic oscillator?

"Hauv Yooj Yim Harmonic Motion, qhov siab tshaj plaws ntawm qhov nrawm nrawm tshwm sim ntawm x=+/-A (qhov kawg kawg qhov twg quab yuam siab tshaj plaws) , thiab acceleration ntawm nruab nrab (at x=0) is zero." a=(d²x /dt²)=-Aω^{2cos (ωt).}

Dab tsi yog txoj hauj lwm hauv oscillation?

Mean Position lossis Equilibrium Position: Nws yog ib txoj hauj lwm ntawm lub cev thaum lub net force ua rau nws yog xoom. Theem ntawm ib tug particle nyob rau hauv oscillatory motion: Qhov no sawv cev rau lub xeev ntawm kev co ntawm lub particle ntawm ib lub sij hawm.
