Thaj chaw tuaj yeem sawv cev raws li vector kom muaj nuj nqis vim nws muaj ob qho tib si thiab kev taw qhia. Cov kev taw qhia ntawm cheeb tsam vector ntawm ib tug nto yog raws perpendicular mus rau qhov chaw. … Tom qab ntawd, thaj chaw yog scalar.
Puas yog cheeb tsam yog vector kom muaj nuj nqis?
Nyob rau hauv 3-dimensional geometry thiab vector calculus, ib cheeb tsam vector yog vector combining ib cheeb tsam kom muaj nuj nqis nrog ib qho kev taw qhia, yog li sawv cev rau thaj chaw taw qhia hauv peb qhov ntev. Txhua qhov bounded nto hauv peb qhov ntev tuaj yeem cuam tshuam nrog thaj chaw tshwj xeeb vector hu ua nws cheeb tsam vector.
Puas yog cheeb tsam A scalar kom muaj nuj nqis?
Qhov loj ntawm cheeb tsam yog scalar quantity.
txhais li cas los ntawm cheeb tsam vector?
: tus vector ntawm lub dav hlau nto nws qhov loj yog thaj tsam ntawm daim duab thiab nws txoj kev taw qhia yog qhov perpendicular rau lub dav hlau ntawm daim duab.
Vim li cas thiaj hu ua vector kom muaj nuj nqis?
VELOCITY HU A VECTOR QUANTITY Vim nws muaj ob qho tib si MAGNITUDE thiab DIRECTION..
