Lub zog yog pauv ntawm ib yam khoom mus rau lwm tus thaum muaj kev tshwm sim tshwm sim. Zog los ntawm ntau hom thiab tuaj yeem ua tau kis ntawm ib yam khoom mus rau lwm tus raws li cua sov, lub teeb, los yog kev txav mus los, rau npe ob peb. Daim ntawv no ntawm zog hu ua kinetic zog.
Tom qab ntawd, lub zog hloov pauv ntawm ib daim ntawv mus rau lwm qhov li cas?
zog hloov dua siab tshiab : Kev hloov pauv ntawm ib daim ntawv ntawm zog rau hauv lwm , feem ntau rau hloov tus zog mus rau hauv ib tug ntau pab tau daim ntawv .thawj txoj cai ntawm thermodynamics: Zog muaj peev xwm tsis raug tsim los sis raug puas tsuaj. daim ntawv ntawm zog : Cov ntawv ntawm zog muaj xws li cua sov, lub teeb, hluav taws xob, mechanical, nuclear, suab thiab tshuaj.
Qhov thib ob, lub zog txuag thiab hloov pauv li cas? Hauv physics thiab chemistry, txoj cai ntawm kev txuag ntawm zog hais tias tag nrho zog ntawm ib qho isolatedsystem tseem nyob tas li; hais tias yog khaws cia ua haujlwm dhau sijhawm. Txoj cai no txhais tau tias zog tsis tuaj yeem tsim nordestroyed; theej, nws tsuas yog hloov los yog pauv ntawm ib daim ntawv mus rau lwm qhov.
Hais txog qhov no, lub zog hloov pauv thiab hloov pauv li cas?
Zog txav thiab hloov daim ntawv. Kev hloov hluav taws xob tshwm sim thaum zog txav ntawm ib qho mus rau lwm qhov. Zog tuaj yeem txav los ntawm ib qho mus rau lwm qhov, zoo li thaum lub zog los ntawm koj qhov txav taw yog pauv mus ncaws pob, los yog zog tuaj yeem hloov ntawm ib daim ntawv mus rau lwm qhov.
Dab tsi yog 10 lub zog hloov pauv piv txwv?
Piv txwv ntawm hnub-rau-hnub EnergyTransformations Tshuaj Zog yog hloov dua siab tshiab rau hluav taws xob Zog (kub), Kinetic Zog (tsheb), Hluav taws xob ( zog cog), thiab Mechanical Zog (spaceshuttle).

Dab tsi tshwm sim rau qhov kub ntawm cov khoom thaum lub sij hawm hloov pauv?
Thaum lub sijhawm hloov pauv, qhov kub ntawm ib yam khoom tseem nyob tas li. Peb feem ntau saib cov theem hloov ntawm cov khoom mus rau cov kua, xws li cov dej khov yaj. Qhov no yog vim hais tias cov cua sov uas tau muab rau cov dej khov molecules yog siv los ua kom lawv lub zog kinetic, uas yog tshwm sim hauv qhov kub thiab txias
Yuav ua li cas rau lub zog thaum nws hloov ntawm ib daim ntawv mus rau lwm qhov?
Kev hloov pauv hluav taws xob yog thaum lub zog hloov ntawm ib daim ntawv mus rau lwm qhov - zoo li hauv lub tshuab hluav taws xob uas hloov lub zog kinetic ntawm dej rau hauv hluav taws xob. Thaum lub zog tuaj yeem hloov pauv lossis hloov pauv, tag nrho lub zog tsis hloov pauv - qhov no yog hu ua kev txuag hluav taws xob
Yuav ua li cas tshwm sim thaum lub zog tsis sib npaug ua rau ntawm ib qho khoom txav?
Yog hais tias ib yam khoom muaj ib tug net force ua rau nws, nws yuav ceev. Cov khoom yuav ua kom nrawm, qeeb lossis hloov kev taw qhia. Lub zog tsis sib npaug (net force) ua rau ntawm qhov khoom hloov nws qhov nrawm thiab / lossis kev taw qhia ntawm kev txav. Lub zog tsis sib npaug yog lub zog tsis muaj zog uas ua rau muaj kev hloov pauv ntawm kev txav mus los
Yuav ua li cas tshwm sim rau lub zog binding thaum lub loj tus naj npawb nce?
Daim duab saum toj no qhia tau hais tias raws li cov atomic huab hwm coj nce, lub zog khi ntawm ib lub nucleon txo qis rau A> 60. Hauv lwm lo lus, BE / A tau txo qis. BE/A ntawm lub nucleus yog qhov qhia txog nws qhov kev ruaj ntseg. Feem ntau, cov nuclides ruaj khov muaj ntau dua BE / A dua li cov tsis ruaj khov
Lub zog rau kev thauj mus los ntawm qhov twg thiab vim li cas thiaj li xav tau lub zog rau kev thauj mus los?
Kev thauj mus los nquag yog txheej txheem uas yuav tsum tau txav cov molecules tawm tsam qhov concentration gradient. Cov txheej txheem yuav tsum muaj zog. Lub zog rau cov txheej txheem tau txais los ntawm kev rhuav tshem cov piam thaj siv oxygen hauv kev ua pa aerobic. ATP yog tsim thaum ua pa thiab tso tawm lub zog rau kev thauj mus los
