Ib Cov khoom muaj peev xwm muaj ob qho tib si kinetic thiab muaj peev xwm zog tib lub sijhawm. Piv txwv li, ib khoom uas yog ntog, tab sis tseem tsis tau mus txog hauv av muaj kinetic zog vim nws txav mus deb, thiab muaj peev xwm zog vim tias nws muaj peev xwm txav mus rau qhov chaw qis dua qhov nws twb muaj lawm.

Ua raws li qhov xav tau, vim li cas cov khoom muaj ob qho tib si kinetic thiab lub zog muaj peev xwm?

Cov khoom ntawm cov khoom muaj kinetic thiab muaj peev xwm zog vim cov zog no yog tsav los ntawm lub zog ntawm kev txav los yog qhov tseem ceeb ntawm ib qho khoom. Kinetic zog ntawm qhov tod tes, yog tus zog nyob rau hauv kev txav los yog yog tias cov khoom txav los ntawm ib qho chaw mus rau lwm qhov nrog rau lub sijhawm.

Kuj Paub, ib yam khoom puas muaj lub zog kinetic tab sis tsis muaj lub zog muaj peev xwm muab piv txwv? Ib piv txwv ntawm ib khoom uas nkaus xwb muaj kinetic zog yuav yog ib tug photon, nyob rau hauv mechanics, yog. Los ntawm txhais, lub = zero oif muaj peev xwm zog yog arbitrary. Ib khoom uas muaj swb mus rau hauv qab ntawm lub toj yuav muaj xoom gravitational muaj peev xwm zog thiab tsis yog -zero kinetic zog.

Ib tug kuj yuav nug, hom zog twg yog ob qho tib si muaj peev xwm thiab kinetic?

mechanical zog

Puas yog txhua yam khoom muaj peev xwm muaj zog?

Kinetic thiab peev xwm muaj zog muaj nyob rau hauv txhua yam khoom . Yog ib khoom yog tsiv, nws hais rau muaj kinetic zog (KE). Muaj peev xwm zog (PE) yog zog uas yog "kho" vim yog txoj haujlwm thiab / lossis kev npaj ntawm cov khoom . Thiab hauv kev poob, tuaj yeem tawm dag zog thiab ua ua hauj lwm rau lwm tus khoom.
