Ukungqubuzana kungamandla avimbela ukunyakaza kwento. La mandla asebenza phakathi kwezindawo ezixhumene. Kulesi sihloko, ukungqubuzana okufundwe kuhlobene namandla asebenza phakathi kwezindawo ezimbili eziqinile ezixhumene, njengokungqubuzana phakathi kwesisekelo sebhloko nephansi, ukungqubuzana phakathi kwesisekelo sesicathulo nephansi, noma ukungqubuzana phakathi kwesondo lemoto nomgwaqo.
Ukungqubuzana kuhlala kusebenza ezindaweni zezinto eziqinile ezithintana, noma ngabe izinto zishelela kakhulu. Ngisho nobuso bento ebushelelezi kakhulu empeleni buqinile kakhulu esikalini esincane kakhulu . Lapho into ihamba, la maqhubu amancane kakhulu aphazamisa ukunyakaza. Ezingeni le-athomu, ukuqhubuzana ebusweni kubangela ukuthi ama-athomu asondele kakhulu kwenye indawo, ukuze amandla kagesi phakathi kwama-athomu akhe isibopho samakhemikhali, njengokuhlangana phakathi kwezindawo ezimbili zento ehambayo. Lapho into ihamba, isibonelo uma ucindezela incwadi phezu kobuso betafula, ukunyakaza kwencwadi kuba nokuphikiswa futhi ekugcineni kuyeke. Lokhu kungenxa yokwakheka nokukhululwa kwalezi zibopho.
Uma ubuso bento eyodwa bugudlana nobuso bento enye, into ngayinye inamandla okungqubuzana kwenye. Ukungqubuzana entweni ehambayo kuhlala kusebenza ngendlela ephambene nesiqondiso sokunyakaza kwento. Ngaphandle kokuvimbela ukunyakaza kwento, ukungqubuzana kungabangela ukuguguleka nomonakalo. Singakubona lokhu ezinjinini zezimoto. Isibonelo, uma sigcoba injini yesithuthuthu, empeleni sifuna ukunciphisa ukungqubuzana ngaphakathi kwenjini. Uma singayigcobi, injini izohluleka ngokushesha. Lesi sibonelo singenye yezinto ezimbi ezibangelwa ukungqubuzana.
Izinhlobo Zamandla Okulwa
Kunezinhlobo ezimbili zokungqubuzana: okungaguquki (f s ) kanye nokujiya (f k ). Ukungqubuzana okungaguquki kusebenza lapho into isahamba, kanti ukungqubuzana okungaguquki kusebenza lapho into ihamba. Uma ucindezela itafula kodwa lisahamba, amandla asebenza etafuleni elingaguquki awukuthi ukungqubuzana okungaguquki. Ngokuphambene nalokho, lapho itafula lihamba, amandla asebenza etafuleni awukuthi ukungqubuzana okungaguquki. Uma itafula elihambayo lingacindezelwa njalo, lizoma ngemva kwesikhashana. Ithebula liyama ngenxa yamandla okujiya avimbela ukunyakaza kwalo.
Wake washelela entweni eshelelayo? Uma ushelela, amandla asebenza phakathi kwesisekelo sesicathulo sakho noma isandali kanye nendawo eshelelayo kuyi-kinetic friction. Lokhu kufana nalapho isithuthuthu noma imoto ehamba emgwaqweni omanzi, oshelelayo ibhulekiswa kuze kube yilapho amasondo eshelela. Lapho amasondo eshelela, amandla asebenza ebusweni besondo kanye nomgwaqo kuyi-kinetic friction. Ngokuphambene nalokho, uma uhamba, amandla asebenza phakathi kwesisekelo sesicathulo sakho noma isandali kanye nephansi kuyi-static friction. Ngokufanayo, lapho isondo lingasheleli, amandla okushelela asebenza ebusweni besondo kanye nomgwaqo ayi-static friction.
