Txij li thaum particle tuaj yeem txav raws ib txoj kab, y '' tsuas yog ib feem ntawm nws txoj kev nrawm, thiab nws nyob hauv txoj kab ntawm kev txav. Yog li, yog tias a = y '' yog qhov zoo thiab v yog qhov zoo, ces ceev yog nce . Yog tias qhov zoo thiab v yog qhov tsis zoo, ceev yog txo . Yog tias qhov tsis zoo thiab v yog qhov zoo, ceev yog txo.

Raws li txoj cai, yog qhov ceev nce lossis txo qis?

Ceev yog nce thaum lub ceev thiab acceleration muaj tib lub cim. Ceev yog txo thaum lub nrawm thiab nrawm muaj cov cim sib txawv.

Tsis tas li ntawd, qhov nce ceev txhais li cas? Kev nrawm yog cov tus nqi hloov ntawm qhov nrawm nrog lub sijhawm. Ib qho kev hloov pauv hauv qhov nrawm ntawm ib qho khoom ua rau muaj kev nrawm: nce ceev (cov neeg feem ntau yog dab tsi txhais tau tias thaum lawv hais acceleration), txo qis ceev (tseem hu ua deceleration lossis retardation), lossis hloov kev taw qhia (hu ua centripetal acceleration).

Raws li, qhov ceev ntawm cov khoom puas tuaj yeem nce ntxiv thaum nws acceleration txo?

Yog, ib yam khoom ua tau yuav nce nyob rau hauv ceev raws li cov acceleration txo . Yuav kom nkag siab tib yam, koj yuav tsum tau txais lub tswv yim ntawm lub ntsiab lus ntawm kev ceev . Theoretically, kev ceev yog tus nqi ntawm kev hloov ceev thaum ceev yog qhov loj ntawm qhov nrawm.

Koj qhia li cas yog qhov nrawm nce lossis txo qis?

Koj tuaj txog ntawm cov lus teb uas koj twb paub lawm. Nco ntsoov tias thaum acceleration yog tsis zoo - nyob rau hauv lub ncua sij hawm [0, 2) - uas txhais tau hais tias lub ceev yog txo . Thaum twg acceleration yog qhov zoo - ntawm lub caij (2, 4] - lub nrawm nce . Kev nrawm nrawm thiab qeeb qeeb.
