Qhov sib txawv tseem ceeb ntawm kev sib tsoo zoo kawg nkaus thiab kev sib tsoo zoo kawg nkaus yog tias nyob rau hauv kev sib tsoo zoo kawg nkaus, tag nrho lub zog kinetic ntawm cov khoom tseem zoo ib yam, whereas, hauv kev sib tsoo zoo kawg nkaus, tag nrho lub zog kinetic ntawm cov khoom tsis nyob twj ywm. tib yam.
Kev sib tsoo zoo kawg nkaus yog qhov sib txawv ntawm kev sib tsoo zoo kawg nkaus. Kev sib tsoo yog txheej txheem lub cev ntawm ob yam khoom tawm tsam ib leeg.
Dab tsi yog kev sib tsoo zoo kawg nkaus?
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 lub 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 daim ntawv thov ntawm elastic sib tsoo 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 kev sib tsoo zoo tag nrho?
Kev sib tsoo zoo kawg nkaus yog qhov txheej txheem ntawm lub cev ntawm kev tawm tsam ib yam khoom tawm tsam lwm yam yam tsis tau txuag lub zog kinetic ntawm ob yam khoom. Qhov no yog qhov opposite ntawm kev sib tsoo zoo kawg nkaus elastic. Lub zog kinetic tsis tau khaws cia hauv kev sib tsoo zoo kawg nkaus vim muaj kev sib txhuam sab hauv.
Txawm li cas los xij, kev sib tsoo inelastic zoo li ua raws li kev txuag lub zog txawm hais tias cov kev sib tsoo no tsis txuag lub zog kinetic. Hauv thaj tsam ntawm nuclear physics, peb tuaj yeem txheeb xyuas qhov sib tsoo tsis sib xws hauv cov khoom xa tuaj uas ua rau cov nucleus zoo siab lossis tawg. Ntawm no, sib sib zog nqus inelastic scattering yog ib qho txheej txheem uas soj ntsuam cov qauv ntawm subatomic hais qhia zoo kawg nkaus inelastic sib tsoo.
Dab tsi yog qhov txawv ntawm Perfectly Elastic thiab Perfectly Inelastic Sib tsoo?
Elastic thiab inelastic sib tsoo yog cov txheej txheem ntawm lub cev uas koom nrog kev tawm tsam ntawm ib qho khoom tawm tsam lwm yam khoom. Qhov sib txawv tseem ceeb ntawm kev sib tsoo zoo kawg nkaus elastic thiab zoo kawg nkaus inelastic sib tsoo yog tias nyob rau hauv kev sib tsoo zoo kawg nkaus elastic, tag nrho lub zog kinetic ntawm cov khoom tseem zoo ib yam, whereas, nyob rau hauv ib qho kev sib tsoo zoo kawg nkaus, tag nrho lub zog kinetic ntawm cov khoom tsis nyob li qub.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm kev sib tsoo zoo kawg nkaus thiab kev sib tsoo zoo kawg nkaus hauv daim ntawv tabular.
Summary – Perfectly Elastic vs Perfectly Inelastic Collision
Kev sib tsoo zoo kawg nkaus yog qhov sib txawv ntawm kev sib tsoo zoo kawg nkaus. Qhov sib txawv tseem ceeb ntawm kev sib tsoo zoo kawg nkaus thiab zoo kawg nkaus inelastic sib tsoo yog tias nyob rau hauv kev sib tsoo zoo kawg nkaus elastic, tag nrho lub zog kinetic ntawm cov khoom tseem zoo ib yam, whereas, nyob rau hauv zoo kawg nkaus inelastic sib tsoo, tag nrho kinetic zog ntawm cov khoom tsis nyob twj ywm tib yam.
