Qhov sib txawv tseem ceeb ntawm kev sib tsoo elastic thiab kev sib tsoo zoo kawg nkaus yog tias kev sib tsoo elastic cuam tshuam nrog kev sib ntsib ntawm ob lub cev nrog kev hloov pauv tsis txaus ntseeg hauv tag nrho lub zog kinetic, qhov kev sib tsoo zoo kawg nkaus yuav tsis muaj kev hloov pauv ntawm lub zog kinetic rau lwm cov ntaub ntawv lub zog.
Elastic thiab zoo kawg nkaus elastic sib tsoo yog ob lub tswv yim tshuaj hauv kev tshuaj ntsuam chemistry. Cov no yog cov ntsiab lus zoo sib xws.
Elastic Sib tsoo yog dab tsi?
Elastic collision yog kev tawm tsam ntawm ib yam khoom tawm tsam lwm yam khoom nrog kev hloov pauv tsis zoo ntawm lub zog. Daim ntawv zoo tshaj plaws ntawm cov tswv yim tshuaj no yog kev sib tsoo zoo kawg nkaus uas tsis muaj kev hloov pauv hauv tag nrho lub zog kinetic tom qab kev tawm tsam ntawm ob yam khoom. Tab sis nyob rau hauv lub neej tiag tiag, yeej ib txwm muaj kev hloov nyob rau hauv tag nrho cov kinetic zog qhov twg ib co ntawm lub zog hloov mus rau lwm yam zog, tab sis nyob rau hauv elastic kev sib tsoo, nyob rau hauv sib piv rau inelastic kev sib tsoo, qhov kev hloov ntawm kinetic zog yog negligible.
Daim duab 01: Elastic Sib tsoo
Thaum lub sijhawm tawm tsam ntawm ib yam khoom nrog lwm yam khoom, ua ntej, lub zog kinetic hloov pauv tag nrho rau hauv lub zog muaj peev xwm, uas cuam tshuam nrog lub zog quab yuam los yog txaus nyiam ntawm ob yam khoom. Tom qab ntawd, lub zog muaj peev xwm hloov rov qab mus rau lub zog kinetic. Feem ntau, kev sib tsoo ntawm atoms yog elastic.
Yuav Ua Li Cas Thiaj Ua Tau Zoo Tshaj Plaws?
Kev sib tsoo zoo kawg nkaus yog lub cev txheej txheem ntawm kev tawm tsam ib qho khoom tawm tsam lwm tus, txuag lub zog kinetic ntawm ob yam khoom. Kev sib tsoo zoo kawg nkaus yog kev sib tsoo zoo tshaj plaws uas tsis muaj kev hloov pauv ntawm lub zog kinetic rau lwm cov ntaub ntawv hluav taws xob xws li cua sov, suab nrov, lossis lub zog muaj peev xwm. Tab sis nyob rau hauv lub neej tiag tiag, tsis muaj kev sib tsoo zoo kawg nkaus vim tias lub zog kinetic ib txwm nyiam hloov mus rau lwm yam zog.
Feem ntau, thaum sib tsoo ntawm lub cev me me, lub zog kinetic nyiam hloov mus ua lub zog ua ntej (uas cuam tshuam nrog lub zog quab yuam ntawm ob lub cev). Qhov no tshwm sim thaum cov khoom txav tawm tsam lub zog quab yuam. Tom qab ntawd lub zog muaj peev xwm zoo li hloov rov qab mus rau lub zog kinetic. Qhov no tshwm sim thaum cov khoom txav nrog lub zog quab yuam. Hauv kev sib tsoo zoo kawg nkaus, lub zog hloov pauv tsis pom lub zog poob.
Raws li qhov piv txwv ntawm lub neej tiag tiag, kev sib tsoo ntawm atoms yog qhov sib tsoo zoo kawg nkaus. Piv txwv li, Rutherford backscattering yog ib qho kev siv ntawm kev sib tsoo elastic ntawm atoms. Tsis tas li ntawd, cov molecules hauv cov pa roj lossis cov kua dej tsis tshua pom muaj kev sib tsoo zoo kawg nkaus. Ntxiv nrog rau cov no, peb tuaj yeem kwv yees kev sib tsoo zoo kawg nkaus los ntawm kev sib cuam tshuam ntawm cov khoom xws li cov pob billiard.
Dab tsi yog qhov sib txawv ntawm Elastic thiab Perfectly Elastic Sib tsoo?
Elastic thiab zoo kawg nkaus elastic sib tsoo yog ob lub tswv yim tshuaj hauv kev tshuaj ntsuam chemistry. Qhov sib txawv tseem ceeb ntawm kev sib tsoo elastic thiab kev sib tsoo zoo kawg nkaus yog tias kev sib tsoo elastic cuam tshuam nrog kev sib ntsib ntawm ob lub cev nrog kev hloov pauv tsis txaus ntseeg hauv tag nrho lub zog kinetic, thaum kev sib tsoo zoo kawg nkaus yuav tsis muaj kev hloov pauv ntawm lub zog kinetic rau lwm cov ntaub ntawv lub zog. Kev sib tsoo ntawm atoms, kev sib tsoo ntawm cov pob hauv kev ua si billboard, thiab lwm yam yog cov piv txwv ntawm kev sib tsoo elastic thaum kev sib tsoo zoo kawg nkaus suav nrog kev sib tsoo uas zoo tagnrho.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm kev sib tsoo elastic thiab kev sib tsoo zoo kawg nkaus.
Summary – Elastic vs Perfectly Elastic collision
Elastic thiab zoo kawg nkaus elastic sib tsoo yog ob lub tswv yim tshuaj hauv kev tshuaj ntsuam chemistry. Qhov sib txawv tseem ceeb ntawm kev sib tsoo elastic thiab kev sib tsoo zoo kawg nkaus yog tias kev sib tsoo elastic cuam tshuam nrog kev sib ntsib ntawm ob lub cev nrog kev hloov pauv tsis txaus ntseeg hauv tag nrho lub zog kinetic, qhov kev sib tsoo zoo kawg nkaus yuav tsis muaj kev hloov pauv ntawm lub zog kinetic rau lwm hom zog.
