Yini umfutho komzimba

Impulse ... Umqondo ngokuvamile sisetshenziswa physics. Asho ukuthini leli gama? Uma ubuza lo mbuzo kowakhileyo elula, ezimweni eziningi, sizobe uthole impendulo ukuthi umfutho zomzimba - kuba nomthelela othile (push noma buhlungu) bafakela umzimba, ukuze bakwazi ukuhambisa ngendlela isiqondiso esinikezwayo. On wonke, incazelo ngempela lesifanele.

umfutho zomzimba - ukuzimisela esikuyo kuhlangana kwabo kokuqala esikoleni: isifundo physics wasibonisa indlela Roll phansi weloli elithile elincane futhi wabhekana ibhola ezifana zensimbi i ebusweni ezintweni ezingafanele. Yingaleso sikhathi-ke thina babecabanga ukuthi kungenzeka sinomthelela amandla kanye nesikhathi mkhuba ngokomzimba. Kulezi kokuma neziphetho, futhi eminyakeni eminingi edlule Ngazalwa nomqondo umzimba njengoba izici ukunyakaza ishayela, encike ngqo kwi isivinini kanye nenqwaba into.

Igama elithi isayensi esethula engumFulentshi Rene Dekart. Kwathi ekuqaleni kwekhulu XVII. Ososayensi ukuchaza umfutho komzimba nje kuphela ngekutsi "inani traffic." In amazwi Descartes yena, uma omunye umzimba ezihambayo ishayisa enye, usawoti kakhulu bamandla alo njengoba unikeza esinye into. bezikhali ngomzimba, ngokwezinto physics, ingabe usekhona, kodwa umane sidluliselwe kusuka entweni eyodwa kuya kwenye.

Isici esiyinhloko zazo Unomzimba ishayela kuyinto orientation yayo. Ngamanye amazwi, kuba ubuningi vector. Ngakho kusukela kulesi sitatimende nokuthi zonke umzimba motion, has a umfutho eziqondile.

Formula ukuchayeka bento eyodwa kuya kwenye: p = mv, lapho v - Isivinini komzimba (Vector ubuningi), m - mass emzimbeni.

Nokho, umfutho zomzimba - ubuningi hhayi kuphela ukuthi inquma ukunyakaza. Kungani abanye umzimba, ngokungafani abanye, qinani kuye isikhathi eside?

Impendulo yalo mbuzo bekulokhu ukuvela esinye mqondo - ngiyibona ebheka lemali nobude ukuchayeka kahle le ndaba. Kusenza sikwazi ukuzwa ukuthi inqume indlela umfutho yomzimba isikhathi esithile. ngokubhuduzela limelela umkhiqizo ngempendulo (amandla langempela) isikhathi sokusebenza kwawo (isikhathi).

Omunye izici eziphawulekayo kakhulu IT is baligcine azizange zishintshe, inqobo irherho le-closed. Ngamanye amazwi, ngokungabi bikho namanye amathonya phezu kwezinto ezimbili, phakathi umfutho komzimba ngeke sizinzile nje ufuna. Isimiso nokongiwa kungaba kucatshangelwe esimweni lapho umthelela zangaphandle ku into ekhona, kodwa umthelela walo Vector kuyinto 0. Futhi, umfutho ngeke kushintshe esimweni lapho umthelela la mandla, noma kancane izenzo emzimbeni esifushane kakhulu isikhathi (njengalapho shot).

Kuyinto lo mthetho ukulondolozwa iminyaka engaphezu kwekhulu, is haunted by abasunguli, baye yayingidida ukudalwa notorious "ezinyakazayo esiphakade", njengoba nguye itholakala ngesisekelo imiqondo ezifana jet ngamandla.

Ngokuphathelene isicelo ulwazi mayelana lomkhuba, njengoba umfutho yomzimba, bajwayele ekuthuthukiseni yezikhali ezicitshwayo, izikhali kanye entsha, uma kungekhona okuphakade, izindlela.
