Yog hais tias ob qho tib si nyob rau hauv kev sib cuag thiab tsiv mus rau ib tug txheeb ze, ces tus kev sib txhuam nruab nrab ntawm lawv yog hu ua kinetic kev sib txhuam . Rau piv txwv , kev sib txhuam slows ib tug hockey puck zawv zawg ntawm dej khov.
Ib yam li ntawd, qee qhov piv txwv ntawm kev sib txhuam kinetic yog dab tsi?
rub zog dej ntawm koj lub cev. Nres siv lub log..vim kinetic kev sib txhuam thaum lub caij so siv tsheb nres. Taug kev..
- Thaum lub tsheb skids, uas yog kinetic kev sib txhuam.
- Skiing thiab skating.
- Tuav tes ua kom sov.
- Kev txav ntawm glaciers.
- Koj plam hauv pem teb.
Ib yam li ntawd, kinetic kev sib txhuam yog dab tsi sau cov lus qhia? Kinetic kev sib txhuam yog lub zog uas ua rau ntawm qhov chaw txav mus los. Coefficient ntawm kinetic kev sib txhuam tau muab lub Greek tsab ntawv "mu" (Μ), nrog subscript "k". Lub zog ntawm kinetic kev sib txhuam yog Μk lub sij hawm ib txwm quab yuam ntawm ib yam khoom thiab yog qhia nyob rau hauv units ntawm Newton (N).
Tsis tas li ntawd, kev sib txhuam kinetic yog dab tsi?
Kinetic kev sib txhuam yog lub zog uas ua rau ntawm qhov chaw txav mus los. Ib yam khoom uas tau txav mus los ntawm qhov chaw yuav muaj kev quab yuam nyob rau sab nraud thaum nws txav mus. Qhov loj ntawm lub zog nyob ntawm qhov coefficient ntawm kinetic kev sib txhuam nruab nrab ntawm ob hom khoom.
Dab tsi yog kev sib txhuam quab yuam nrog piv txwv?
Ib piv txwv ntawm static kev sib txhuam yog cov zog uas tiv thaiv lub tsheb log tsis txhob ntog thaum nws dov rau hauv av. Txawm hais tias lub log yog nyob rau hauv kev txav, thaj tsam ntawm lub log tsheb hauv kev sib cuag nrog hauv av yog nyob ruaj ruaj rau hauv av, yog li nws zoo li qub es tsis yog kinetic. kev sib txhuam.
