Newton txoj cai thib ob ntawm tsab ntawv tsa suab piav txog qhov kev sib raug zoo ntawm lub zog thiab acceleration . Lawv ncaj qha proportional. Yog koj nce lub zog siv rau ib yam khoom, lub kev ceev ntawm qhov khoom ntawd nce los ntawm tib yam. Hauv luv luv, zog sib npaug lub sij hawm loj kev ceev.

Tsis tas li lo lus nug yog, kev sib raug zoo ntawm kev quab yuam thiab kev nrawm nrawm yog dab tsi?

Txoj Cai Acceleration - Cov kev ceev ntawm ib yam khoom yog ncaj qha proportional rau lub zog ua rau nws thiab inversely proportional rau lub pawg ntawm qhov khoom.

Tsis tas li ntawd, lub zog cuam tshuam li cas rau huab hwm coj thiab acceleration? quab yuam yog ntsig txog rau kev ceev los ntawm qhov sib npaug F = ma. "F" sawv cev rau zog , "m" stands rau pawg thiab "a" sawv rau kev ceev . Yog ib yam khoom muaj pawg , thiab yog ceev los ntawm qhov chaw, ces tus khoom yuav exert a zog . Lub hauv paus ntsiab lus no tau piav qhia los ntawm Newton txoj cai thib ob ntawm kev txav.

Tsis tas li ntawd, qhov kev sib raug zoo ntawm qhov hnyav thiab acceleration yog dab tsi?

A: Cov kev sib raug zoo ntawm huab hwm coj thiab acceleration tau piav nyob rau hauv Newton's Second Law of Motion. Nws Txoj Cai Thib Ob hais tias ntau dua pawg ib yam khoom muaj, ntau zog yog tsim nyog rau nws kom nrawm.

Dab tsi yog peb cov qauv uas piav qhia txog kev sib raug zoo ntawm lub zog loj thiab kev nrawm?

Nws yog ib nqe lus luv luv ntawm Isaac Newton Txoj Cai Thib Ob ntawm Motion, tuav ob qho tib si proportions thiab vectors ntawm Txoj Cai thib ob. Nws txhais tau tias: Net zog ntawm ib yam khoom sib npaug rau tus loj ntawm cov khoom multiplied los ntawm cov acceleration ntawm qhov khoom. quab yuam sib npaug pawg sij hawm kev ceev.
