Ukunyakaza Mechanical - konke ngakho

Kunengqondo ukuphetha ngokuthi igama elithi "ukuhamba mechanical" liyazikhulumela. Isihloko kwaba ngesinye isikhathi, futhi ngemva kwesikhashana wazithola kwelinye - ukuthi kwaba ukuhamba. Nokho, akubona bonke ngakho elula. Ngethemu, ngenhla, amanga anencazelo ejulile.

Ukuhambisa kusuka iphuzu ukuze iphuzu akuyona leso, futhi isikhathi esithile. Futhi hhayi kanye nje kuphela ukusuka endaweni A ukhombe B, futhi namanye imigqa. ukunyakaza komugqa umzimba ngokuthi trajectory ubude balo - wadlula. Chaza ukuziphatha umzimba futhi ngokuvamile trajectory salo ngempela umsebenzi onzima. Kodwa uma sisebenzisa umfanekiso umzimba emkhathini ngosizo izixhumanisi kanye nesikhathi, kuyoba umthetho motion.

Manje umbuzo olandelayo - wenza kahle kanjani ukunyakaza mechanical? Esimweni lapho zonke lihamba iphuzu elifanayo into, ngeke sithuthuke. Nokho, uma umzimba ezihambayo yakhe amaphuzu atholakala indilinga, ukunyakaza ukujikeleza. Lapha sesivele abe nezici motion mechanical, futhi asikho nesisodwa.

Umsebenzi physics akuyona nje incazelo inqubo ukunyakaza, kodwa futhi isibikezelo lapho umzimba kungaba ngesikhathi esithile. Nokho, ukusizakala mthetho motion kanye nezici zayo, kumele sithole yekucala engibukhulumile ngaso zonke izinkokhelo zizokwenziwa. Uma kuchazwa, sizobe ugcwalise uhlelo yenkomba lapho ungakwazi ukuchaza noma iyiphi inhlangano lokukhanda.

Ukudlulisa kwenzeka kwi iphuzu isiqalo Ukudidiyela uhlelo noma, ngamanye amazwi, uzimele inkomba. Point of imvelaphi kungenzeka abakhethiwe ezinqumela, futhi ngesikhathi ushintsho iphuzu incazelo inkomba ezinyakazayo ungavula omunye. Ngakho, sinqume ukuthi ukunyakaza awayindwayo isihlobo. Lo mqondo wokuhlobana kwezinto ngesikhathi owasungulwa uGalileo.

Ukuze quantitatively ukuchaza yonke inqubo ezihambayo, ihlala namanje faka into ezifana isivinini. Ngaphansi ngayo ezinyakazayo Translational kuyinto isilinganiso ukunyakaza ephelele kanye isikhathi esichithwa bale nhlangano. Esimweni lapho izinga ayishintshi isiqondiso nokubaluleka kwalo, ukunyakaza kuyinto ngisho futhi iqonde. Uma ngabe le mfuneko is hhayi bahlangana - ukunyakaza kuyoba okungafanele.

Okusho isivinini - futhi bayalwazisa isihlobo, futhi ancike isiqondiso sayo, ngamanye amazwi, Lokhu ubuningi vector. Uma isitimela ihamba isihlobo ukuba surface eMhlabeni ngesivinini V1 futhi kuwo bebheke isitimela umgibeli nge V2 Isivinini ke maqondana isihambi ezweni izoya ngesivinini V1 + V2. Kodwa uma uzothatha isinyathelo ngokumelene ukunyakaza isitimela ke maqondana emhlabeni, izoya ngesivinini V1 - V2.

Ukuqedela incazelo iyunithi ukunyakaza wokulinganisa kumele kusetshenziswe ukuletha izici. Isikhathi kukalwa ngemizuzwana, uhambo olude - ngamamitha, kahle, ijubane, ngokulandelana, ngamamitha ngomzuzwana.

Ngenhla saxoxa nomqondo ukunyakaza mechanical kusukela umbono physics. Nokho, lo mbono kutholakala isayensi ethile komunye umkhakha. Ngakho, igama elithi "ukuhamba mechanical sabantu," usebenza izibalo kwezenhlalo noma kwezomnotho. Enye igama leli gama - ukufuduka. Luhilela ukunyakaza kwabantu badabula leyo ndawo yomuntu (zwe, republic, izifunda), kanye nokunyakaza ezinjalo lihlotshaniswa ushintsho lokuhlala.

Indaba ka nomqondo onjalo kubhekwa, njengoba ngokunyakaza mechanical, futhi incazelo izici zayo. I izakhiwo motion - trajectory, isivinini, ibanga - futhi ukunikeza umqondo jikelele we kwezinto motion. Nangezibonelo ukusetshenziswa imiqondo efanayo neminye imikhakha yesayensi.
