Qhov loj dua pawg ntawm kev txav khoom , qhov tsawg yooj yim nws txav. Raws li Newton txoj cai thib ob ntawm tsab ntawv tsa suab , acceleration uas khoom kev paub yog inversely proportional rau nws pawg , thiab koj tuaj yeem xam qhov acceleration no los ntawm cov khoom hloov nyob rau hauv ceev tshaj lub sij hawm teem.

Tom qab ntawd, ib tug kuj yuav nug, yuav ua li cas loj npaum li cas cuam tshuam lub zog ntawm ib yam khoom?

Yog ob khoom yog tib yam pawg , thiab txawv zog siv rau lawv Cov khoom uas tau txais ntau dua zog yuav ceev ceev, thiab cov khoom uas tau txais qhov tsawg dua zog yuav tsis ceev kom ceev Yuav ua li cas koj slow down khoom uas txav?

Tsis tas li ntawd, qhov loj puas cuam tshuam rau kev txav mus los? Kev piav qhia: Pawg tsis cuam tshuam rau hauv projectile zog . Dab tsi yog qhov tseem ceeb yog qhov pib ceev thiab kev taw qhia ntawm cov khoom.

Ib yam li ntawd, tej zaum koj yuav nug tias, qhov loj npaum li cas cuam tshuam rau qhov ceev ntawm cov khoom txav?

Pawg tsis yog cuam tshuam ceev ncaj qha. Xwb, pawg txiav txim siab npaum li cas lub zog yuav tsum ua kom nrawm khoom ntawm tus nqi muab. Sib dua khoom ua tau ua nrog tsis muaj zog quab yuam hloov ceev los ntawm tus nqi muab rau hauv ib lub sijhawm.

Kev hloov loj cuam tshuam li cas cov khoom sib tsoo?

Hloov hauv Pawg Ib cov khoom loj thiab lub zog yog ncaj qha ntsig txog; raws li pawg nce, momentum yuav muaj qhov sib txuam nce, piv txwv li qhov nrawm nrawm. Yog li ntawd, ib khoom nrog ob zaug pawg ntawm lwm tus khoom -- txav ntawm tib qhov ceev thiab nyob rau tib txoj kev -- yuav muaj ob zaug lub zog.
