Thermodynamics: Kinetic thiab Muaj Peev Xwm Zog . Kinetic zog yog zog muaj los ntawm ib yam khoom nyob rau hauv motion. Lub ntiaj teb revolving ib ncig lub hnub, koj taug kev ntawm txoj kev , thiab molecules txav hauv qhov chaw txhua tus muaj kinetic zog.
Ib yam li ib tug yuav nug, yog Qab Zib muaj peev xwm lossis lub zog kinetic?
Cov chemical bonds hauv qab zib tawg li cov qab zib yog digested rau carbon dioxide thiab dej. Thaum cov chemical bonds tawg, lub muaj peev xwm zog yog tso tawm nyob rau hauv daim ntawv ntawm kinetic zog los yog zog ntawm kev txav thiab cua sov los yog tsis siv tau zog.
Tsis tas li ntawd, piv txwv ntawm lub zog muaj peev xwm yog dab tsi? Piv txwv ntawm lub zog muaj peev xwm suav nrog: Ib pob zeb zaum ntawm ntug pob tsuas. Yog pob zeb ntog, lub muaj peev xwm zog yuav hloov mus rau kinetic zog , raws li lub pob zeb yuav txav mus. Ib tug stretched elastic hlua nyob rau hauv ib tug longbow. Thaum cov hlua elastic raug tso tawm, nws yuav ua rau tus xub tua rau pem hauv ntej.
Tom qab ntawd, lo lus nug yog, yog tus neeg caij tsheb kauj vab pedaling nce toj roob kinetic zog?
Yog hais tias koj pedal ib lub tsheb kauj vab ntawm qhov ceev ntawm ib theem ntawm cov av, nws muaj ib tug ruaj khov npaum li cas. kinetic zog . Raws li nws ceev thiab txoj kab nqes yog tas li, nws / nws kinetic zog yog tas li. Cov mis yog KE = / m * v * v qhov m = mass thiab v = velocity.
Ib co piv txwv ntawm kinetic zog yog dab tsi?
13 Piv txwv ntawm Kinetic Zog hauv Lub Neej Txhua Hnub
- Tsav Tsheb. Cov tsheb txav muaj qee qhov kinetic zog.
- Bullet Los ntawm Phom. Ib lub mos txwv raug rho tawm ntawm rab phom muaj lub zog kinetic siab heev, thiab, yog li, nws tuaj yeem nkag tau yooj yim rau txhua yam khoom.
- Flying Airplane.
- Taug kev & Khiav.
- Kev caij tsheb kauj vab.
- Rollercoasters.
- Cricket Pob.
- Skateboarding.

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
Dab tsi yog kev sib raug zoo ntawm gravitational muaj peev xwm zog thiab kinetic zog?
Thaum ib yam khoom ntog, nws lub peev xwm gravitational hloov mus rau kinetic zog. Koj tuaj yeem siv qhov kev sib raug zoo no los xam qhov ceev ntawm qhov khoom qhovntsej thiaj tsis mob. Gravitational muaj peev xwm zog rau ib pawg m ntawm qhov siab h nyob ze ntawm lub ntiaj teb yog mgh ntau tshaj li lub zog muaj peev xwm yuav nyob rau qhov siab 0
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
Puas yog lub zog hauv daim ntawv ntawm kev txav yog lub zog muaj peev xwm?
Lub zog nyob rau hauv daim ntawv ntawm kev txav yog 'muaj peev xwm' zog. Qhov ntau dua 'mas' ib qho khoom txav muaj, lub zog kinetic nws muaj. Lub pob zeb ntawm ntug pob tsuas muaj 'kinetic' zog vim nws txoj hauj lwm. 'Thermal' zog yog lub zog khaws cia los ntawm cov khoom uas ncab los yog compression
