Hauv lwm lo lus, tag nrho tus nqi ntawm zog nyob tas li. On ib cov menyuam coaster , zog hloov ntawm peev xwm rau kinetic zog thiab rov qab ntau zaus thaum caij tsheb. Kinetic zog yog zog uas ib yam khoom muaj los ntawm nws cov lus tsa suab. Muaj peev xwm zog yog khaws cia zog uas tseem tsis tau tso tawm.
Tsis tas li ntawd, qhov twg muaj peev xwm thiab lub zog kinetic ntawm tus menyuam coaster?
Gravitational muaj peev xwm zog yog qhov loj tshaj ntawm qhov siab tshaj ntawm a cov menyuam coaster thiab tsawg kawg ntawm qhov qis tshaj plaws. Kinetic zog yog zog ib qho khoom muaj vim nws cov lus tsa suab thiab sib npaug rau ib nrab ntawm qhov loj ntawm ib qho khoom sib npaug los ntawm nws qhov nrawm squared (KE = 1/2 mv2).
Qhov thib ob, tus menyuam coaster tau txais lub zog li cas? Qhov tseem ceeb a cov menyuam coaster yog lub ntiajteb txawj nqus tsheb ciav hlau. Cov cov menyuam coaster tsheb nce lub zog muaj peev xwm raws li lawv raug rub mus rau saum toj ntawm thawj lub roob. Raws li cov tsheb nqis los muaj peev xwm zog hloov mus rau kinetic zog . Cov coaster tsheb muaj qhov siab tshaj plaws kinetic zog lawv yeej yuav muaj txhua lub caij.
Tsis tas li lo lus nug yog, lub peev xwm thiab lub zog kinetic cuam tshuam li cas?
Muaj peev xwm zog yog zog khaws cia rau hauv ib qho khoom vim nws txoj haujlwm lossis kev npaj. Kinetic zog yog zog ntawm ib yam khoom vim nws txav - nws cov lus tsa suab. Txhua yam ntawm zog tuaj yeem hloov mus rau lwm hom zog.
Cov piv txwv ntawm lub zog muaj peev xwm yog dab tsi?
Piv txwv ntawm Lub Zog Muaj Peev Xwm
- Lub caij nplooj ntoos hlav coiled.
- Lub log ntawm cov menyuam skates ua ntej ib tug neeg skates.
- Ib tug archer hneev nrog txoj hlua rub rov qab.
- Ib qho hnyav hnyav.
- Cov dej uas nyob tom qab lub pas dej.
- Ib pob snow (muaj peev xwm avalanche)
- Ib tug quarterback txhais caj npab ua ntej ntuav dhau.
- Ib tug stretched roj hmab band.

Dab tsi yog qhov txawv ntawm electrostatic muaj peev xwm thiab electrostatic muaj peev xwm zog?
Tsis muaj qhov sib txawv ntawm electrostatic potentialenergy thiab hluav taws xob (al) muaj peev xwm zog. Lub peev xwm hluav taws xob ntawm ib qho taw tes yog kev ua haujlwm los ntawm lwm qhov kev quab yuam hauv kev txav chav tsev zoo los ntawm ib qho arbitrarilychosen xoom ntawm lub peev xwm (feem ntau infinity) mus rau lub ntsiab lus
Puas muaj peev xwm hluav taws xob thiab lub zog muaj peev xwm tib yam Vim li cas lossis vim li cas ho tsis?
Lub zog muaj peev xwm hluav taws xob Ue yog lub zog muaj peev xwm khaws cia thaum cov nqi tawm ntawm qhov sib npaug (xws li lub zog muaj peev xwm gravitational). Lub peev xwm hluav taws xob zoo ib yam, tab sis ib tus nqi, Ueq. Ib qho hluav taws xob muaj peev xwm sib txawv ntawm ob lub ntsiab lus hu ua voltage, V = Ue2q−Ue1q
Newton txoj cai ntawm kev txav mus li cas cuam tshuam rau cov menyuam coasters?
Thiab Newton thawj txoj cai ntawm kev txav mus los qhia tau hais tias ib qho khoom ntawm so yuav nyob twj ywm tshwj tsis yog tias muaj kev quab yuam sab nraud siv rau nws. Newton txoj cai thib peb ntawm tsab ntawv tsa suab hais tias, 'Rau txhua qhov kev txiav txim muaj qhov sib npaug thiab tawm tsam.' Yog li ntawd siv rau cov menyuam coaster, nruab nrab ntawm cov tsheb caij tsheb thiab khiav
Dab tsi yog cov qauv ntawm lub zog nyob rau hauv lub peev xwm thiab lub zog kinetic?
Lub zog muaj peev xwm yog khaws cia lub zog thiab lub zog ntawm txoj haujlwm - lub zog gravitational. Muaj ntau hom kev muaj peev xwm muaj zog. Kinetic zog yog kev txav - ntawm nthwv dej, electrons, atoms, molecules, tshuaj, thiab khoom. Chemical Zog yog lub zog khaws cia hauv cov khoom sib txuas ntawm atoms thiab molecules
