Acceleration uas tsis hloov nyob rau hauv lub sij hawm yog hu ua uniform los yog tas li acceleration. Nyob rau hauv ib tug ceev piv rau lub sij hawm graph rau uniform acceleration, txoj kab nqes ntawm txoj kab yog acceleration. … Cov kab zauv uas piav txog qhov nkhaus yog vf=vi+at.
Dab tsi yog daim duab ntawm kev nrawm nrawm?
Hint: Kev nrawm-lub sijhawm teeb tsa ntawm ib qho khoom txav nrog kev nrawm nrawm. Thaum lub nrawm nrawm - lub sijhawm teeb tsa tau npaj rau ib qho khoom txav nrog kev nrawm nrawm, txoj kab nqes ntawm daim duab yog kab ncaj, tus qauv ntawm txoj kab nqes ntawm daim duab qhia tias cov khoom txav mus los tsis sib xws acceleration.
Daim duab ntawm qhov nrawm nrawm yog dab tsi?
Kev nrawm nrawm txhais tau tias nrawm nrawm muaj qhov nqes tsis tu ncua. Yog tias qhov nrawm nrawm zuj zus, txoj hauj lwm daim duab yuav tsum muaj txoj kab nqes zuj zus. Lub acceleration tsis tu ncua ua rau lub parabolic txoj hauj lwm graph. Ib zaug ntxiv, qhov kev hloov pauv yog thaj chaw hauv qab qhov nkhaus ntawm daim duab nrawm.
acceleration yog dab tsi?
A qhov tsis tu ncua lossis kev nrawm nrawm txhais tau tias qhov nrawm ntawm cov khoom hloov pauv los ntawm tib tus nqi txhua ob. Thaum qhov ceev ntawm ib qho khoom poob qis nrog lub sijhawm (xws li qeeb qeeb), qhov khoom nrawm hloov pauv thiab yog li, los ntawm kev txhais, cov khoom yog nrawm.
Yuav ua li cas yog tus qauv rau kev nrawm nrawm?
Zaj. Acceleration uas tsis hloov nyob rau hauv lub sij hawm yog uniform, los yog tas li, acceleration. Covequation hais txog qhov pib tshaj tawm, qhov kawg tshaj tawm, lub sij hawm, thiab acceleration yog vf=vi+at.
