Txawm hais tias nws yog kev sib tsoo lossis tawg, yog tias nws tshwm sim hauv qhov kev sib cais, ces txhua yam khoom cuam tshuam ntsib tib lub zog ua rau tib lub zog hloov pauv. Lub impulse thiab lub zog hloov ntawm txhua yam khoom sib npaug hauv qhov loj thiab qhov sib txawv ntawm kev coj. Yog li, tag nrho lub zog lub zog tau khaws cia
Puas yog lub zog thiab lub zog kinetic khaws cia hauv qhov tawg?
Kev tawg tshwm sim thaum lub zog hloov pauv los ntawm ib hom xws li. tshuaj muaj peev xwm zog rau lwm yam xws li. tshav kub zog los yog lub zog kinetic ceev heev. Yog li, zoo li hauv kev sib tsoo inelastic, tag nrho lub zog kinetic tsis tau khaws cia hauv kev tawg. Tab sis tag nrho lub zog yog ib txwm khaws cia.
Puas yog lub zog ib txwm khaws cia?
Momentum yeej ib txwm txuag, tsis hais hom kev sib tsoo. Pawg tau txais kev cawmdim tsis hais hom kev sib tsoo ib yam nkaus, tab sis qhov loj yuav raug deformed los ntawm kev sib tsoo tsis sib xws, ua rau ob pawg thawj coj tau daig ua ke.
Puas tawg tawg tsis muaj zog lossis elastic?
Kev sib tsoo yog xav tias tsis muaj zog thaum lub zog kinetic tsis txuag, tab sis qhov no tuaj yeem yog los ntawm kev poob lossis nce lossis lub zog kinetic. Piv txwv li, nyob rau hauv ib tug tawg-hom kev sib tsoo, lub kinetic zog nce. Nws yog ib qho uas tib neeg sim txuag lub zog hauv kev sib tsoo.
Puas yog Newton lub txaj txaj elastic lossis inelastic?
Newton's Cradle visualizes an elastic collision los ntawm kev tso cai rau cov tub ntxhais kawm pom qhov loj li ntau lub npas, thiab qhov nrawm raws li qhov siab ntawm cov khoom mus ncig.
