SI unit: kilogram meter per second kg⋅m/s

Tsis tas li ntawd, SI unit ntawm lub zog hauv Newton yog dab tsi?

Cov newton thib ob (kuj newton -thib ob, cim N s lossis N. · s) yog muab los SI unit of impulse . Nws yog dimensionally sib npaug rau cov momentumunit kilometer ib ob (kg.

Tsis tas li ntawd, cov ntsiab lus ntawm lub zog kinetic teb li cas ntawm kg / m thiab / lossis S? Yog qhov loj muaj units ntawm kilograms thiab qhov ceev ntawm meters ib ob, lub kinetic zog muaj units ntawm kilograms - ' meter ' squared ib ob squared. Kinetic zog yog feem ntau ntsuas hauv units ntawm Joules(J); ib jul yog sib 1 kg m ua 2 / s 2.

Qhov thib ob, ntsuas li cas hauv kgm s?

Ib kilogram-meter ib ob (kg. s -1) yog tus qauv chav tsev ntawm lub zog. Txo rau lub hauv paus units hauv International System of Units (SI), ib kilogram-meter ib ob yog qhov sib npaug ntawm ib tug newton-thib ob (N. · s ), uas yog SI unit ntawm impulse.

Lub zog cuam tshuam li cas rau Newton txoj cai?

Newton tus Thib ob Txoj cai – link to Newton txoj cai . Tus nqi hloov ntawm lub zog ntawm ib yam khoom yog ncaj qha proportional rau lub resultant quab yuam thov thiab yog nyob rau hauv cov kev taw qhia ntawm lub resultant quab yuam. Lub resultant quab yuam yog sib npaug rau tus nqi hloov ntawm lub zog.
