Ib qho yooj yim pendulum muaj ib tug loj dai los ntawm ib tug ze ze ntawm massless hlua uas swings txog ib tug pivot. Gravitational muaj peev xwm zog (GPE) yog tus zog vim txoj hauj lwm uas sib npaug rau mgh qhov twg h yog qhov siab sib txawv ntawm nws txoj hauj lwm qis tshaj plaws mus rau qhov twg nws tau tsiv mus rau.

Ib yam li ib tug yuav nug, puas yog lub pendulum muaj peev xwm muaj zog?

Tag nrho cov zog hauv pendulum yog gravitational muaj peev xwm zog thiab tsis muaj kinetic zog . Ntawm qhov qis tshaj (Point D) lub pendulum muaj nws qhov ceev tshaj plaws. Tag nrho cov zog hauv pendulum yog kinetic zog thiab tsis muaj gravitational muaj peev xwm zog.

Tsis tas li ntawd, lub zog hloov pauv hauv lub pendulum yog dab tsi? Raws li ib tug pendulum swings, nws muaj peev xwm zog hloov mus rau kinetic thiab rov qab mus rau qhov muaj peev xwm. Nco qab lub tswvyim ntawm kev txuag ntawm zog - tias zog muaj hloov nws daim ntawv, tab sis tsis muaj net hloov mus rau tus nqi ntawm zog.

Tsis tas li ntawd, qhov twg lub pendulum muaj lub zog tshaj plaws?

Yog kinetic zog yog siab tshaj hauv qab ntawm lub pendulum , ces yog qhov twg muaj peev xwm zog yog qhov qis tshaj. Yog li muaj peev xwm zog yuav yog siab tshaj thaum lub pendulum yog ntawm nws siab tshaj taw tes rau ntawm ob sab ntawm nws cov lus tsa suab uas nws nyob ruaj khov rau ib qho instant.

Thaum lub pendulum swings thaum twg yog lub peev xwm lub zog loj tshaj?

Yog li ntawd, a swinging pendulum muaj nws loj tshaj kinetic zog thiab tsawg kawg muaj peev xwm zog nyob rau hauv txoj hauj lwm ntsug, nyob rau hauv uas nws ceev yog loj tshaj thiab nws qhov siab tsawg kawg nkaus; nws muaj qhov tsawg kawg nkaus kinetic zog thiab lub zog loj tshaj plaws ntawm lub extremities ntawm nws viav vias , nyob rau hauv uas nws ceev yog xoom thiab nws qhov siab yog loj tshaj.
