Hindura metero ninshuro zayo
Uzuza imwe muri metero igwire urebe impinduka.
Ibibazo bishimishije nibisubizo bijyanye na metero ninshuro zayo
Metero ni iki?
Ni ryari kandi ni hehe metero (ubumwe bwintera) yatangijwe?
Nibihe bigwiza metero?
Ibipimo na byinshi byayo: Umugongo wo gupima isi yose
Mu rwego rwo gupima, ijambo "metero" rikora nk'ibuye rikomeza imfuruka ya sisitemu ya metero yo kugereranya uburebure cyangwa intera. Byasobanuwe kumugaragaro na sisitemu mpuzamahanga yubumwe (SI) nkuburebure bwagenze nurumuri mu cyuho mugihe kiri hagati ya 1 / 299,792,458 yisegonda, metero nikintu cyemewe na bose gishobora gupima neza kandi neza. Mu ikubitiro hashingiwe kuri prototypes yumubiri, ibisobanuro bya metero byahindutse hamwe no gusobanukirwa siyanse, biganisha kumiterere yubu ikomoka kumiterere yibidukikije kugirango hamenyekane neza.
Imikoreshereze ya metero yaguwe binyuze muburyo butandukanye hamwe na submultiples, ihujwe no guhuza ibintu byinshi. Ku munzani minini, kilometero (metero 1.000) isanzwe ikoreshwa mugupima intera nkumwanya uri hagati yimijyi cyangwa uburebure bwa marato. Kurundi ruhande rwikigereranyo, uburebure buto nkubugari bwimisatsi yumuntu cyangwa ubunini bwibintu bya microscopique birashobora kugaragazwa byoroshye ukoresheje submultiples nka milimetero (1/1000 bya metero) cyangwa micrometero (1 / 1.000.000 ya metero) . Ibindi bikoresho byakomotse nka santimetero (1/100 cya metero) usanga bikoreshwa kenshi mubuzima bwa buri munsi, nko gupima ibipimo by'ibikoresho cyangwa uburebure bwa muntu.
Imibare ntabwo aribwo buryo bwonyine bwo gupima metero, ariko. Inyandiko ya siyansi yemerera kwerekana uburebure bunini cyane cyangwa buto muburyo bworoshye. Kurugero, ubunini bwikirere bushobora kugaragara buri kuri metero 10 26 , mugihe diameter ya atome igera kuri metero 10 -10 . Ukoresheje ubumenyi bwa siyansi, ibipimo mubipimo bitandukanye cyane birashobora kugereranywa no kubarwa muburyo bumwe, bifasha mubintu byose kuva mubuhanga kugeza muri fiziki ya fiziki.
Nka nkibice fatizo byuburebure, metero ihujwe imbere nizindi SI ibice binyuze mubice bikomokaho. Kurugero, metero kumasegonda (m / s) igereranya umuvuduko, mugihe metero kare (m²) na metero kibe (m³) zikoreshwa mukarere nubunini, kimwe. Ibice nkibikomokaho nibyingenzi mubice bitandukanye nkubwubatsi bwa gisivili, aho metero kare zishobora gukoreshwa mugutegura ikibanza hasi, cyangwa mumashanyarazi, aho metero kibe kumasegonda zishobora kwerekana umuvuduko.
Muri rusange, metero ninshuro zayo zitanga sisitemu ihuriweho yorohereza ubufatanye bwisi yose niterambere mubumenyi, ubwubatsi, nubucuruzi. Mugutanga igice gisanzwe gishobora gupimwa cyangwa kumanuka ukurikije imiterere, sisitemu ya metero yemeza ko umuntu yaba ategura umushinga wubwubatsi waho cyangwa gutobora amayobera yisi, ururimi rwo gupima rukomeza kuba rwumvikana kandi rusobanutse neza.
