Nyob hauv ntiaj teb no kev sib tsoo feem ntau yog qhov chaw hauv nruab nrab elastic thiab zoo kawg nkaus inelastic. Ib lub pob poob los ntawm qhov siab h saum npoo av feem ntau thaws rov qab rau qee qhov siab tsawg dua h, nyob ntawm seb lub pob khov npaum li cas. Cov kev sib tsoo zoo li no tsuas yog hu ua kev sib tsoo inelastic.
Puas muaj kev sib tsoo tsis sib haum?
Ib qho kev sib tsoo inelastic yog ib feem ntawm lub zog kinetic hloov mus rau lwm hom zog hauv kev sib tsoo. Txhua qhov kev sib tsoo macroscopic ntawm cov khoom yuav hloov qee lub zog kinetic rau hauv lub zog sab hauv thiab lwm yam ntawm lub zog, yog li tsis muaj qhov cuam tshuam loj loj yog qhov zoo kawg nkaus elastic.
Koj ua pov thawj li cas kev sib tsoo tsis zoo?
Koj pom kev sib tsoo tsis sib haum thaum cov khoom sib txuas ua ke tom qab sib tsoo, xws li thaum ob lub tsheb sib tsoo thiab sib txuas lawv tus kheej ua ib qho. Txawm li cas los xij, cov khoom tsis tas yuav los ua ke hauv kev sib tsoo inelastic; txhua yam uas yuav tsum tau tshwm sim yog qhov poob ntawm qee lub zog kinetic.
Qhov twg muaj tseeb rau kev sib tsoo tsis sib haum?
Nyob rau hauv kev sib tsoo tsis sib haum, momentum tau txuag tab sis lub zog kinetic tsis txuag.
Puas cov khoom sib txuas ua ke hauv kev sib tsoo tsis sib haum?
Tib neeg qee zaum xav tias cov khoom yuav tsum tau ua ke hauv kev sib tsoo tsis sib xws. Txawm li cas los xij, khoom tsuas yog lo ua ke thaum muaj kev sib tsoo zoo kawg nkaus. Cov khoom kuj tseem tuaj yeem sib tsoo los yog tawg sib nrug,thiab kev sib tsoo tseem suav tias yog tsis muaj zog yog tias lub zog kinetic tsis txuag.
