1 Coefficient ntawm kev sib txhuam. … Nws yog ib qho piv txwv ntawm lub zog ntawm kev sib txhuam ntawm ob lub cev thiab lub zog nias lawv ua ke. Tus coefficient ntawm kev sib txhuam zoo li qub yog qhov piv ntawm qhov siab tshaj plaws kev sib txhuam quab yuam (F) ntawm qhov chaw hauv kev sib cuag ua ntej kev txav mus losrau qhov qub (N) quab yuam.
Koj pom qhov coefficient ntawm kev sib txhuam zoo li cas?
Tus qauv los xam cov coefficient ntawm kev sib txhuam yog μ=f÷N. Kev sib txhuam quab yuam, f, ib txwm ua nyob rau hauv qhov sib txawv ntawm qhov kev xav lossis qhov tseeb, tab sis tsuas yog sib npaug mus rau saum npoo.
Tus qauv rau coefficient ntawm kev sib txhuam yog dab tsi?
coefficient ntawm kev sib txhuam, qhov sib piv ntawm kev sib txhuam quab yuam tiv thaiv kev txav ntawm ob qhov chaw hauv kev sib cuag mus rau qhov qub quab yuam nias ob qhov chaw ua ke. Nws feem ntau yog cim los ntawm Greek tsab ntawv mu (μ). Kev ua lej, μ=F / N, qhov twg F yog lub zog sib txhuam thiab N yog lub zog ib txwm.
Koj pom qhov coefficient ntawm static thiab kinetic kev sib txhuam li cas?
Tus qauv yog µ=f / N, qhov twg µ yog qhov sib txhuam ntawm kev sib txhuam, f yog tus nqi zog uas tawm tsam, thiab N yog lub zog ib txwm muaj.
Coefficient ntawm kev sib txhuam zoo li qub thiab kev sib txhuam kinetic yog dab tsi?
Tus coefficient ntawm kinetic kev sib txhuam yog qhov piv ntawm kinetic kev sib txhuam quab yuam (F) ntawm qhov chaw nyob rau hauv kev sib cuag thaum lub sij hawm txav mus rau lub zog ib txwm Ff /NWS. … Rau ib khub ntawm qhov chaw, qhov coefficient ntawm kev sib txhuam zoo li qub yog loj dua qhov kev sib txhuam kinetic. Qhov coefficient ntawm kev sib txhuam yog nyob ntawm cov khoom siv.
