Umthetho ukulondolozwa amandla - legumbi

Emisebenzini yazo yansuku zonke umuntu isebenzisa ezahlukene amandla: ezishisayo, mechanical, zenuzi, kagesi, njll Nokho, nakuba sizoxoxa nje omunye ezakheke - lokukhanda. Ikakhulukazi kusukela iphuzu Ngenxa umlando physics, yaqala nge ekutadisheni mechanical ukunyakaza, namandla kanye nokusebenza. Ngesinye isikhathi kumiswa isayensi kwaba ukuthola umthetho ukulondolozwa amandla.

Uma sicabanga imihlola mechanical ukusebenzisa imibono ka kinetic futhi amandla ezingaba khona. Yasungulwa Ucwaningo ukuthi amandla ingabe usekhona ngokuphelele, komunye uhlobo komunye, sikhule size. Kunengqondo ukuphetha ngokuthi okwakushiwo ifomu jikelele kakhulu washayelwa umthetho ukulondolozwa eneji mechanical.

Okokuqala, kufanele kuphawulwe ukuthi isamba zivele futhi energy kinetic yomzimba ngokuthi amandla lokukhanda. Ngaphezu kwalokho okudingeke ukuba sikhumbule ukuthi umthetho ukulondolozwa amandla Imininingwane mechanical sivumelekile ku engekho isinyathelo zangaphandle kanye ukulahlekelwa eyengeziwe ngenxa, isibonelo, zokunqoba amabutho ukumelana. Uma noma iyiphi yalezi izidingo ziphuliwe ke ushintsho amandla kuzokwenzeka yokulahlekelwa yayo.

Ukuhlolwa elula ukuqinisekisa mibandela umngcele, wonke umuntu angakwazi ukuma baqine. Thatha ibhola ku iphimbo nimyeke ahambe. Hit phansi, yena uyokwenza ukugxuma bese futhi kuwele phansi, futhi bagxume futhi. Kodwa isikhathi ngasinye ukuphakama enzeke kuyoba sazikhohlwa, kuze ibhola uyokuma kungahambi phansi.

Lokho esikubonayo kule ndaba? Lapho ibhola kuyinto umile futhi ezingeni ukuphakama, it has amandla ezingaba kuphela. Lapho kuwa iqala, anakho ijubane, futhi ngenxa yalokho, kukhona energy kinetic. Kodwa njengoba ukuphakama bawe ukunyakaza waqala, kuba ngaphansi, futhi ngenxa yalokho, kuba esingaphansi ezingaba namandla, okungukuthi, ke uguqulwe energy kinetic. Uma sifeza izibalo, kuvela ukuthi amagugu amandla bayalingana, okusho ukuthi umthetho ukulondolozwa amandla ngaphansi kwezimo ezinjalo wenziwa.

Nokho, isibonelo esinjalo, kukhona thuthuva ezimbili izimo ngaphambilini osungulwe. Ibhola ihamba emoyeni futhi ezungezwe ozithola ukumelana kungxenye yakhe, kungakhathaliseki ukuthi kuncane. Futhi amandla kwandziswa ekunqobeni ukumelana. Ngaphezu kwalokho, ibhola ishayisa phansi futhi bounces, okusho azizwa isenzo zangaphandle, futhi ukuphulwa izimo umngcele, okuyizinto ezidingekayo ukuze umthetho ukulondolozwa amandla yesibili abemahle.

Ekugcineni, ibhola kuzuba ayeke, futhi ngeke siyeke. Zonke amandla zokuqala ezitholakalayo uzobe wachitha zokunqoba emoyeni ukumelana kanye nethonya zangaphandle. Nokho, ngaphandle ukuguqulwa wamandla zizokwenziwa umsebenzi ukuze sinqobe amandla ukuhilizisana. Lokhu kuyoholela ekuthuleni Ukushisa komzimba. Ngokuvamile, ukubaluleka Ukushisa akuyona elibaluleke kakhulu, futhi kungenziwa kuphela kunqunywe nesilinganiso ngokunemba amathuluzi, kodwa enjalo lokushisa ushintsho lapho.

Ngaphezu mechanical, kukhona nezinye izinhlobo zamandla - ukukhanya, kagesi, amakhemikhali. Nokho, kuzo zonke izinhlobo zamandla kuyiqiniso ukuthi munye uhlobo inguquko kwenye, futhi ukuthi lezi zinguquko amandla ingqikithi zonke izinhlobo alushintshi. Lokhu kuqinisekisa uhlamvu jikelele ukongiwa amandla.

Lapha kumelwe uqaphele ukuthi ukudluliselwa amandla kungaba ukulahlekelwa engenamsebenzi wakhe. Lapho ubufakazi imihlola mechanical Ukushisa lesifishane evele ambient noma uxhumana.

Ngakho, into elula mechanical wasivumela ukuba sithole mthetho ukulondolozwa amandla futhi izimo umngcele ukuqinisekisa ukuqaliswa kwayo. Kwatholakala ukuthi ukuguqulwa amandla Kwenziwa kunoma yiluphi uhlobo etholakalayo omunye wathi Kutholwe umthetho jikelele.
