Ib inelastic kev sib tsoo tshwm sim thaum ob yam khoom sib tsoo thiab tsis txhob sib ntaus sib tua. Momentum yog khaws cia , vim tag nrho lub zog ntawm ob yam khoom ua ntej thiab tom qab lub kev sib tsoo yog tib yam. Txawm li cas los xij, kinetic zog tsis yog khaws cia . Yuav luag tsis muaj zog yog ploj mus rau suab, cua sov, los yog deformation.
Tsis tas li nug, vim li cas lub zog kinetic tsis khaws cia hauv kev sib tsoo inelastic?
Kinetic zog tsis txuag hauv ib inelastic sib tsoo , tab sis qhov ntawd yog vim nws hloov dua siab tshiab rau lwm daim ntawv zog (heat, thiab lwm yam). Qhov sib npaug ntawm txhua hom zog (xws li kinetic ) yog tib yam ua ntej thiab tom qab lub kev sib tsoo.
Ib sab saum toj no, lub zog kinetic poob li cas hauv kev sib tsoo inelastic? Nyob rau hauv ib tug zoo kawg nkaus inelastic sib tsoo , i.e., xoom coefficient of restitution, the kev sib tsoo cov khoom sib txuas ua ke. Nyob rau hauv xws li ib tug kev sib tsoo , kinetic zog yog poob los ntawm kev khi ob lub cev ua ke. Qhov kev sib raug zoo no zog feem ntau ua rau qhov siab tshaj plaws kinetic zog poob ntawm qhov system.
Ntawm no, puas yog lub zog kinetic txuag hauv kev sib tsoo?
Thaum khoom sib tsoo , tag nrho lub zog ntawm lub system yog ib txwm khaws cia yog tias tsis muaj sab nraud quab yuam ua haujlwm ntawm qhov system. Kinetic zog (KE) yog zog ntawm motion, thiab kinetic zog tsis yog ib txwm khaws cia hauv kev sib tsoo . Ib qho elastic kev sib tsoo yog ib qhov twg kinetic zog yog khaws cia.
3 hom kev sib tsoo yog dab tsi?
Muaj peb hom kev sib tsoo Txawm li cas los xij, elastic, inelastic, thiab inelastic kiag li.
- elastic - kinetic zog yog khaws cia.
- inelastic - lub zog kinetic tsis txuag.
- tag nrho inelastic - lub zog kinetic tsis txuag, thiab cov khoom sib tsoo ua ke tom qab kev sib tsoo.

Puas yog taug kev ntawm txoj kev muaj peev xwm lossis lub zog kinetic?
Thermodynamics: Kinetic thiab muaj peev xwm zog. Kinetic zog yog lub zog muaj los ntawm ib yam khoom hauv kev txav. Lub ntiaj teb tig ib ncig ntawm lub hnub, koj taug kev hauv txoj kev, thiab cov molecules txav hauv qhov chaw txhua tus muaj lub zog kinetic
Dab tsi yog qhov txawv ntawm kev txuag hluav taws xob thiab lub hauv paus ntsiab lus ntawm kev txuag hluav taws xob?
Lub caloric txoj kev xav tau khaws cia tias cov cua sov tsis tuaj yeem tsim los yog rhuav tshem, qhov kev txuag ntawm lub zog ua rau lub hauv paus ntsiab lus tsis sib xws uas cov cua sov thiab cov tshuab ua haujlwm sib hloov tau
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
Lub zog ntawm kev cuam tshuam ntawm lub tsheb sib tsoo yog dab tsi?
Lub zog ntawm kev cuam tshuam txhais - cuam tshuam quab yuam sib npaug F yog qhov nruab nrab cuam tshuam quab yuam, m yog qhov loj ntawm ib yam khoom, v yog qhov pib ceev ntawm ib yam khoom, d yog qhov kev ncua deb ntawm kev sib tsoo
