Kuyini ukubaluleka vector kanye scalar lokho? Cishe nje eziyinkimbinkimbi

amagama amabili kukhona wesikole uyathusa - vector kanye scalar - empeleni esabekayo. Uma uza nendaba ngesithakazelo, zonke ongakuqonda. Lesi sihloko iyobheka ukuthi inani vector, futhi abanye scalar. Okuningi ngokunembile, izibonelo samanje. Umfundi ngamunye kumele Nginakile, ukuthi i-physics, ezinye amagugu ibhalwe uphawu hhayi kuphela, kodwa umcibisholo kusuka phezulu. Yini zazisho ukuthini? Lokhu kuzoxoxwa ngakho ngezansi. Sizama ukuba baqonde umahluko phakathi ubuningi Vector ye scalar.

Izibonelo zithwala. Basuke ezikhonjwe

Asho vector? Zinjani ukunyakaza. Akunandaba, emkhathini noma indiza. Kuyini ukubaluleka vector nhlobo? Ngokwesibonelo, indiza is flying ngesivinini ezithile ezingeni ukuphakama ethile, has a isisindo ethize, waqala ezihambayo befika nje esikhumulweni sezindiza ne ukusheshisa kunesidingo. Lokho libhekisela ukuhamba izindiza? Yini eyamenza fly? Yiqiniso, ijubane ukushesha. Vector ingcosana physics Yiqiniso uyisibonelo esihle. Ukubeka ngembaba, ubuningi Vector elihlobene ne ukunyakaza, ukunyakaza.

Amanzi, futhi, ihamba ngesivinini ezithile kusukela eziphakeme entabeni. Uyabona? Le nhlangano yenkolo yokulwela kwenziwe ngenxa akukho ivolumu noma okusindayo, okungukuthi isivinini. Tennis kwenza kube nokwenzeka ukuhambisa ibhola usebenzisa yethenisi. Ubeka ukusheshisa. By the way, kuleli cala, i-force applied futhi ngobuningi le-vector. Kungoba etholwe ngenxa ngesivinini esethiwe futhi accelerations. Amandla Ungakwazi futhi ziyahlukahluka, afeze izenzo ezithile. The Wind Lokho Shakes le amahlamvu ezihlahla, futhi, kungaba kubhekwe njengesibonelo. Njengoba kukhona ijubane.

amagugu emihle nemibi

A Vector ubuningi kuyinto eliningi ukuthi unalo isiqondiso esikhaleni ezizungezile futhi module. Kwathi futhi ngelinye izwi okwesabisayo, kulokhu iyunithi. Cabanga ukuthi udinga ukuxazulula puzzle, okuyinto kuzolungiswa by value omubi ukushesha. Emvelweni, amagugu negative, kubonakala, alikho. Njengoba ijubane ingaba mibi?

Esikhathini Vector into enjalo. Lokhu kusebenza, isibonelo, amabutho ukuthi zisetshenziswa umzimba, kodwa abe izinkomba ezahlukene. Khumbula eyesithathu umthetho Newton, lapho isenzo ilingana counteraction. The guys ukudonsa intambo. Omunye iqembu e amahembe okwesibhakabhaka, kwesibili - ziphuzi. Lesi sakamuva banamandla. Ake sithi vector force iqondiswa kahle. Ngesikhathi esifanayo, kuqala akunakwenzeka ukudonsa intambo, kodwa zama. Kukhona amandla aphikisanayo.

Vector noma ubuningi scalar?

Ake sixoxe umehluko phakathi ubuningi Vector ye scalar. Yini ipharamitha akanayo isiqondiso, kodwa kunencazelo ehlukile? Nazi ezinye amagugu scalar ngezansi:

• isikhathi (eyesibili, ngomzuzu, usuku, ngonyaka);
• mass (amalutshwana kusiya, kilogram, ton);
• ubude ibanga (isentimitha imitha ikhilomitha);
• endaweni kanye umthamo (imitha cubic kanye sikwele);
• Izinga lokushisa (degrees Celsius, Fahrenheit);
• umthamo ngemisebe, emisebeni (ibha, X-ray);
• umsindo, vibration (ama-decibel angu).

Ingabe zonke isiqondiso? Cha Kuyini ukubaluleka vector kanye scalar okuyinto ongabonisa izibonelo ezichaza kabanzi ezithathwe kuphela. Ngo-physics, kukhona imiqondo, hhayi nje kuphela "Mechanics, Dynamics kanye kinematics", kanye esigabeni "Ugesi Magnetism". amandla Lorentz, lokungeniswa, amandla kazibuthe - konke lokhu njengoba Vector kobukhulu.

Vector kanye scalar e amafomula

Ngo izincwadi physics ifomula njalo lapho kukhona umcibisholo phezulu. Khumbula umthetho wesibili Newton. Amandla ( "F" nge umcibisholo ngenhla) uyalingana mass komkhiqizo ( "m") nokusheshisa (u- "a" nge umcibisholo phezulu). Njengoba kushiwo ngenhla, amandla nokusheshisa kukhona vector eziningi, kodwa isisindo - scalar.

Ngeshwa, akuyona yonke izincwadi kufanele ukuqokwa lezi eziguquguqukayo. Mhlawumbe, lokhu kwenziwa ukuze lula ukuthi abafundi akuzona edukisayo. Kungcono ukuthenga izincwadi nezinkomba, okuyinto kwasho zithwala e amafomula.

Khona-ke iyini ukubaluleka vector sizobonisa umfanekiso. Kunconywa ukuba banake izithombe nemidwebo physics amakilasi. Vector eziningi ube isiqondiso. Lapho iqondiswe amandla adonsela phansi? Yiqiniso, phansi. Ngakho, umcibisholo uboniswa siye ohlangothini olufanayo.

I amakolishi obuchwepheshe basafunda physics ukujula. Ngo eyala eziningi othisha ukukhuluma ngalokho wamanani scalar futhi vector. Ulwazi olunjalo liyadingeka ezindaweni: ukwakhiwa, ezokuthutha, isayensi.
