<prompt> Izvi zvinokosha zvinodiwa ndizvo zvinosiyanisa contravariant vector kubva kune chero imwe katatu yezvizhinji zvine musoro mumuviri. Somuenzaniso, kana v ine x, y, uye z-zvikamu zvekumhanya, ipapo v ndiyo contravariant vector: kana zviyero zvemuchadenga zvakatambanudzwa, zvakatendeuka, kana zvakapetwa, ipapo zvikamu zvekumhanya zvinoshanduka nenzira imwecheteyo. Kune rumwe rutivi, somuenzaniso, katatu inosanganisira urefu, upamhi, uye kukwirira kwebhokisi rectangular inogona kuita zvikamu zvitatu zvechinyorwa chisina kujairika, asi iyi vector haisi contravariant, sezvo kutenderera kwebhokisi hakushanduri urefu, upamhi, uye kukwirira kwebhokisi. Mienzaniso ye contravariant vectors inosanganisira simba, displacement, electric field, velocity, and momentum, uye chii chinonzi contravariant vectors? Mubvunzo:  <response>: kusuduruka, kumhanya, munda wemagetsi, simba, simba, uye kumhanyisa.
