Cov nruab nrab ceev ntawm ib yam khoom yog nws tag nrho kev hloov chaw muab faib los ntawm tag nrho lub sij hawm coj. Hauv lwm lo lus, nws yog tus nqi ntawm qhov khoom hloov pauv nws txoj haujlwm ntawm ib qho chaw mus rau lwm qhov. Nruab nrab ceev yog Vector kom muaj nuj nqis. SI unit yog meters ib ob.

Tsuas yog li ntawd, qhov nruab nrab tshaj tawm yog dab tsi?

Nruab Nrab Velocity , Ncaj Ncees The nruab nrab ceev ntawm ib yam khoom yog txhais raws li qhov kev ncua deb uas tau muab faib los ntawm lub sij hawm elapsed. Kev nrawm yog vector kom muaj nuj nqis, thiab nruab nrab ceev tuaj yeem txhais tau tias qhov kev hloov pauv tau muab faib los ntawm lub sijhawm.

Ib tug kuj yuav nug, dab tsi yog tus qauv rau kev ceev? daws rau ceev los yog siv tus nqi formula rau ceev , s = d/t uas txhais tau tias ceev sib npaug nrug muab faib los ntawm lub sij hawm. Yuav kom daws tau lub sijhawm siv lub qauv rau lub sij hawm, t = d / s uas txhais tau hais tias lub sij hawm sib npaug zos nrug muab faib los ntawm ceev.

Kuj Paub, tus qauv ntawm qhov nruab nrab ceev thiab qhov nruab nrab tshaj tawm yog dab tsi?

Nruab nrab ceev = Qhov deb / lub sij hawm dhau mus = 180 meters / 6 vib nas this = 30 meters / thib ob. Nruab nrab ceev = Kev xaav / sij hawm dhau mus = 60 meters / 6 vib nas this = 10 meters / thib ob.

SI unit ntawm ceev yog dab tsi?

Cov ntsuas ceev suav nrog: meters ib ob (cim m s⁻¹ los yog m/s), lub SI muab tau chav tsev ; kilometers ib teev (cim km / h); mais ib teev (cim mi / h lossis mph);
