Infinitesimal Displacement : Ib qho tseem ceeb heev hloov vector yog cov hloov vector overan tsis kawg sij hawm. sawv rau lub tsis kawg hloov chaw).
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog qhov hloov pauv vector?
A hloov chaw yog a vector nws qhov ntev yog qhov luv tshaj plaws ntawm qhov pib mus rau qhov kawg txoj hauj lwm ntawm apoint P. Nws quantifies ob qhov kev ncua deb thiab kev taw qhia ntawm animaginary motion raws ib txoj kab ncaj nraim los ntawm thawj txoj hauj lwm mus rau qhov kawg txoj hauj lwm ntawm lub point.
Tsis tas li ntawd, koj yuav nrhiav tau qhov hloov pauv ntawm vector li cas? A hloov vector muab qhov kev hloov pauv: qhov kev ncua deb ntawm qhov chaw pib mus rau qhov kawg pointis qhov loj ntawm qhov hloov vector , thiab txoj kev taug kev mus yog cov kev taw qhia ntawm lub kev hloov pauv . Mus los ntawm tus Tsov tus tw vector mus rau lub taub hau thib ob tau txais koj mus rau koj lub hom phiaj.
Ib yam li ntawd, tib neeg nug, dab tsi yog qhov kev hloov pauv tsis kawg?
Ib rooj plaub tshwj xeeb ntawm ib infinitesimal hloov chaw (feem ntau sau tseg dr), virtual hloov chaw (denotedδr) hais txog ib qho tsis kawg hloov nyob rau hauv positioncoordinates ntawm ib qho system xws li cov kev txwv tseem txaus siab.
Txoj hauj lwm vector thiab hloov vector yog dab tsi?
Cov txoj hauj lwm vector ntawm ib tug particle yog txhais asthe vector pib ntawm lub hauv paus chiv keeb mus rau qhov chaw uas cov particle yog. Cov hloov vector ntawm ib tug particle yog txhais raws li tus vector koom nrog nws thawj zaug txoj hauj lwm nws final txoj hauj lwm . Hauv lwm lo lus, lub kev hloov pauv yog kev hloov hauv txoj hauj lwm vector.
