Isimiso wokuhlobana kwezinto

Ibe isimiso kaGalileo wokuhlobana kwezinto ngokuyinhloko lasakazekela uhlelo lokukhanda. Wathi akukho ukuhlolwa mechanical akunakwenzeka ukuthi noma ngabe uhlelo uyaphumula noma rectilinear iyunifomu ezinyakazayo futhi isimo. Ngamanye amazwi, lapho kokwenza inertial ezahlukene nokudidiyela izinhlelo (ezisebenzayo amabutho inertia) sekushoneni kwalo ukuhlolwa mechanical, imiphumela iyoba efanayo.

UGalileo waphawula ukuthi Mechanics yokushukumisa umzimba, kodwa kunalokho ukushayisana, umthelela, amagobolondo flying nezinye izenzakalo zinganikeza imiphumela efanayo: edlubhe laboratories ezinyakazayo rectilinear, futhi uphumule.

Chaza isimiso mechanical wokuhlobana kwezinto kungaba yilesi sibonelo esilandelayo. Ake ucabange ukuthi enye imoto idlula eceleni ezinye ngaphandle uthuthumele, okungukuthi, ngesivinini njalo ngezikhawu ezithile. Futhi konke ligubuzelwe inkungu ekhasa awugqinsi ukuze inombolo is akubone lutho. Umbuzo lo: kungaba Abagibeli imoto ukuze kunqunywe ukuthi yiziphi wabo ihamba? Singabasiza, okwenza ucwaningo kwi lokukhanda izinto?

It kuvela ukuthi kuleli cala, abagibeli angabuka lokungenani ukunyakaza isihlobo. Naphezu kweqiniso lokuthi yonke imithetho traffic futhi imithetho Vector kwalokho elaklanywa laboratory ezihambayo, bona ungabonisi, "ungazizwa" lona ngokwalo yimuphi umphumela bale nhlangano. I Lesimiso sokuhlobana ubonisa ukuthi akukho ukuhlolwa mechanical sehlulekile ukuthola rectilinear iyunifomu motion uhlelo inkomba isihlobo ukuba izinkanyezi kanye nelanga. Nokho, yashesha ezinyakazayo inkomba uhlelo ngokuhlobene izinkanyezi ilanga kuyalithinta imiphumela ucwaningo.

WaseGalile kwezinto simiso Mechanics, kudingeka siyinake ngokukhethekile. Akekho izinhlelo waseGalile kungeke kwanikezwa ukukhetha isimiso, naphezu kweqiniso lokuthi ngendlela yokuhlakanipha kungcono cabanga luhlaka esithile reference uncamela kuye ngokuthi isimo.

Ngakho-ke, kuhanjwa ngemoto umgibeli Ukudidiyela uhlelo, okuyinto kuhlobene umshini kuyoba isimo inkomba lemvelo, okwedlula lokho okunikwa lihlotshaniswa komgwaqo. Futhi uhlelo yokugcina, esikhundleni salokho, kayibuhlungu komuntu ubukele ukujikeleza imoto, omi eduze komgwaqo. izinhlelo ezihlukahlukene babe waseGalile kwefrakshini kwendikimba okuyinto lubonakaliswa yokuthi ushintsho phakathi izinhlelo ezikhona amafomula afanayo kodwa kuphela inani lefonti ukubaluleka the velocity isihlobo.

Isimiso wokuhlobana kwezinto kubhekwa kusukela iphuzu Ngenxa kinematics, kodwa kwefrakshini enjalo izinhlelo ezahlukene isici futhi Dynamics. Lena isimiso zakudala wokuhlobana kwezinto.

Kukhona isimiso esikhethekile, okuyinto isebenza kubo bonke imihlola ngokomzimba, hhayi kuphela kwi ukunyakaza lokukhanda. essence yayo itholakala iqiniso ukuthi zonke Ukudidiyela izinhlelo ezihambayo isihlobo komunye nomunye nombala futhi rectilinearly, iyiphi imihlola ngokomzimba kwenzeka ngokulinganayo, futhi noma iyiphi ucwaningo ngokomzimba ukunikeza imiphumela efanayo.

Lesi sikhundla uchazwa ngokuthi isimiso okhethekile wokuhlobana kwezinto, njengoba luhlobene amacala olukhethekile rectilinear iyunifomu ezinyakazayo. Kulokhu, zonke imithetho ufune kokubili nokudidiyela izinhlelo ezihlobene izinkanyezi efanayo, kanye nanoma yimuphi omunye izinhlelo ukuthi ukuhambisa efanayo endaweni ngqo umugqa isihlobo ukuba izinkanyezi.

Kukhona futhi isimiso ajwayelekile ukuthi ihlanganisa amacala nokudidiyela izinhlelo nge ezinyakazayo okusheshayo. Ibizwa ngokuthi isimiso jikelele wokuhlobana kwezinto.
