Yuav ua li cas thiaj nrhiav tau lub zog ntawm kev sib txhuam
- Xaiv lub zog ib txwm ua ntawm qhov khoom thiab hauv av. Wb xav tias ib txwm quab yuam 250 N.
- Xaiv qhov kev sib txhuam coefficient. …
- Multiply these values by each other: (250 N)0.13=32.5 N.
- Koj nyuam qhuav pom lub zog ntawm kev sib txhuam!
Yuav ua li cas yog lub mis rau xam kev sib txhuam?
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 rau saum npoo.
Koj ua li cas xam cov kev sib txhuam zoo li qub?
Tus qauv los xam qhov kev sib txhuam zoo li qub yog muab raws li: Static Friction=Normal Force x Static Friction coefficient. Kev sib txhuam zoo li qub=60 N.
Tus qauv quab yuam ib txwm yog dab tsi?
Nyob hauv rooj plaub no yooj yim ntawm ib yam khoom zaum ntawm kab rov tav, lub zog ib txwm yuav sib npaug rau quab yuam ntawm lub ntiajteb txawj nqus F n=m g F_n=mg Fn=mgF, pib subscript, n, kawg subscript, sib npaug, m, g.
5 piv txwv ntawm kev sib txhuam zoo li cas?
Static Friction Examples
- Cov ntaub ntawv ntawm lub rooj.
- phuam dai rau ntawm khib.
- ib phau ntawv hauv phau ntawv.
- Ib lub tsheb nres rau saum toj.
