Imithetho Yokuzivikela Mechanics

Kwezemfundo othisha ohlakaniphile ukutshela abafundi babo ukuthi kukhona umthetho nokongiwa e Mechanics. nencazelo yalo itholakala lokuthi ukuthi amandla e irherho le-closed abakwazi kusaba, ukumosha ukwenza noma yimuphi umsebenzi. Ngo izinqubo ezinjalo akukho ukunyamalala, ukuguqulwa zamandla zenye kwenye. Ngokwesibonelo: chofoza inkinobho - futhi egqamile ukukhanya isibani ukubaniza. Counter kahle cabanga watt amandla owenziwe. Wayesithathaphi uhambe? Kulula: i kagesi enza umsebenzi, lapho le energy is ibe ukukhanya nokushisa. Ngamanye amazwi, imithetho nokongiwa e Mechanics ezifanelekile iyiphi idivayisi mechanical (noma kagesi - umehluko kuphela original amandla nezinhlobo igama Lomkhuba efanayo). Eqinisweni, umthetho nokongiwa kuyinto isimiso esiyisisekelo, owawuthi yonke uhlala.

Okokuqala, kumelwe unqume ukuthi ikuphi amandla kinetic futhi ezingaba khona. Ngamafuphi nje, lo sokuqala amandla motion yomzimba, esibonisa umsebenzi owenziwa emzimbeni. Owesibili okwesikhashana amandla ezinganeni kwesimiso emizimbeni, kunqunywa ubunjalo ukuxhumana kanye indawo lezinto ohlelweni. Kungokwemvelo ukuthi igama elithi lisuselwa lesiLatini elisho ukuthi "ithuba." I Mechanics lezi zinhlobo ezimbili zamandla ibe ngomunye nomunye.

imithetho nokongiwa e Mechanics ukusebenza ngendlela elandelayo. Ngokwesibonelo, into, juba phezulu ngesikhathi ishayela inenani esiphezulu we energy kinetic. Ngakho, Isivinini salo eliphakeme okwamanje kokuqala. kancane kancane It kunciphisa njengoba amandla kinetic iguqulwe ibe ezingaba khona. Ngenxa yalokho, into kubambezela lithi khimilili. Lokhu kusho ukuthi wonke isitokwe of the initial ishayela amandla sashintshwa saba bezikhali futhi yandiswa ohlelweni. Ngaphezu kwalokho, ngenxa ithonya adonsela phansi into iqala ukuna. Neqiniso lokuthi amandla is iguqulwe emuva ku-energy kinetic. Predictably, okwamanje kokuqala ijubane ukunyakaza incane, kodwa kancane kancane kwandisa njengoba kukhulisa energy kinetic kohlelo. Kuyaphawuleka ukuthi kuleli cala, nakuba umphumela we kazibuthe Zomhlaba (ishayela extra), amandla Imininingwane kohlelo uhlala ingashintshiwe.

Ukuze uqonde kangcono imithetho nokongiwa e Mechanics, kunengqondo ukuba baphendukele okuhlangenwe nakho kwazo siqu. Ngokuqinisekile, njengoba ingane, ngamunye kwehla ungene substrate metal incane, kodwa ibhola omkhulu noma ibhola abavamile. Nokho, labhampa up bawa phansi futhi. Lokhu kwaphindwa nje ukuhamba angesabi wanqamuka. Kodwa kuthiwani umthetho ukulondolozwa amandla e lokukhanda izinto? Phela, ngokunengqondo, amandla bezikhali ibhola awela iguqulwe ngokugcwele ku-energy kinetic, futhi okuphambene nalokho. Cishe "ezinyakazayo ngokunganqamuki." Ngempela, kulesi simo imithetho nokongiwa e Mechanics zinganeliswa? Eqinisweni, kulesi simo ohlelweni kuthinta ngomshikisho ngokumelene molecule emoyeni kanye deformation we ebusweni yangaphakathi futhi ibhola. Ngenxa yalokhu, "ukuntshontsha" ingxenye yabo amandla, yingakho ibhola eyeka oshaya kancane kancane (endleleni, ngakho ngo kohlaka Mechanics classical akukwazeki ukudala ngokunyakaza umshini esiphakade).

I jikelele koHlelo imithetho nokongiwa ingayisebenzisa hhayi kuphela kulesi sibalo nokuxhumana macrocosm izinhlelo, kodwa futhi, ngokwengxenye, endaweni sekuba yinto enkulu. Kwalona trajectory ukunyakaza kwanoma yiluphi uhlobo amabutho esebenza ohlelweni akuphazamisi yi - ukongiwa imithetho abasebenza!
