Kuyini amandla adonsela phansi

Ngisho no-Albert Einstein wathi konke - isimangaliso sangempela, futhi wayeqinisile. Singabantu ngenqubo yokuphila yansuku zonke ngokuvamile siyeke uqaphela zemvelo, ukuthatha kalula. A liyobhekana nesiphetho esifana wayengeke aphunyule amandla adonsela phansi. Indaba Funny ezihlobene wokuvula yayo, wonke umuntu uyazi: kwanele ukuba sikhumbule Newton kanye apula eyawela inhloko usosayensi othile.

Umbono wokuthi amandla adonsela phansi ezinjalo, umuntu uthola njengoba ingane. Ngakho, Snowball nendawo aphonswe kancane kancane ukushintsha trajectory yayo, ukuncika phansi uwela phansi. Sledge Roll sehle egqumeni. amaconsi emvula bathambekele umhlaba, njll Futhi nemihuzuko ilimele kusukela ukuwa -. kakhulu, "ukusola" amandla adonsela phansi kuzo.

Umhlaba, njenganoma iyiphi enye iplanethi, edonsela iyiphi kulomzimba, babambeke zone adonsela phansi. Njengoba ibanga ukusuka edonsa into ukuchayeka umfutho incipha. Njengoba iqhwa okhangwa emhlabeni, hhayi indawo abahlala kuya ovundlile ezindizayo iqhwa, kungaba bazitshela ukuthi amandla incike isisindo emzimbeni. Omunye umbuzo: kungani indlela eqhwa ijika, futhi ngokushesha ngemva uphonsa kungenzeki ukuwa ngokushesha? Ngokusobala, ububi libhekene ngegalelo, inenani ezithile ukuthi lingalinganiswa, okuyinto benza Newton.

Wazibuza ukuthi kungani izinto isisindo ezahlukene ewa lobulinganako, ukufinyelela kwamanzi izikhathi ezihlukahlukene. Ukuze sicacise lokhu usosayensi benza eksperimenti lelula: ngamapayipi ingilazi ibekwe izinto eziningana uquqaba ezahlukene, isibonelo, phambili futhi akhanya fluff ibhola. I tube uqobo wadala a cleaner futhi uphendulé ngokusebenzisa 180 degrees. Ngenxa yalokho, zonke izinto ezazisezinyaweni phansi, bazithola phezulu futhi ngaphansi kwethonya gravity wasuphaphatheka. Ukubuka ukuwa, Newton yathola ukuthi zonke izifundo Usufike phansi ngesikhathi esifanayo. Lokhu kwenza ukuba ukusho ukuthi amandla adonsela phansi abangelwa nomphumela ofanayo kuzo zonke izifundo, kungakhathaliseki isisindo sabo.

Nokho, okuhlangenwe nakho kuveza okuhlukile: kamuva iconsi feather ukuhola izwe. Eqinisweni, it is wachaza kalula, ngoba umehluko nje isisindo kodwa futhi khona emoyeni, retarding ekwindla. Lokhu Ukumelana incike kwabantu umzimba, ezakheke futhi ngenxa yalokho, okusezingeni eliphezulu. Ngaphansi kwezimo ezifanele, lapho endaweni yasendle ukusabalala mkhulu ibanga ngokwanele kusukela edonsa into omkhulu (umhlaba) ivame infinity, futhi phakathi ezintweni eziwayo kanye ebusweni akuyona ezithinta ukuhamba medium, ukuwa kuyokwenzeka ukusheshisa efanayo. Ngesikhathi esifanayo, uma siyiqaphele yokuthi amandla adonsela phansi - ungamandla lapho vzaimoprityagivayutsya umzimba, bese ibanga kwaphakade okunganqamukiyo (izimo ezikahle theory), yokwehla ngeke kuthinte nenqwaba into falling. Ngamanye amazwi, nakuba iplanethi has ku uphaphe nebhola umthelela F = m * g, bona-ke okwakumelwe, ukuheha emhlabeni. Kodwa njengoba uquqaba akuzona efanayo, futhi lokhu kuyinto "ezengeziwe" amandla kulesi sibalo kungaba dengwane.

Umthelela gravity kwazisa bonke izifundo ukusheshisa efanayo ngesikhathi ebusweni Zomhlaba, kuba 9,81 m / s². Njengoba sekushiwo, ne ibanga amandla buthakathaka, okuyinto waqinisekiswa izilinganiso emngceleni ongenhla emkhathini - kukhona ukusheshisa engaphansi kuka 9 m / s². Ukusheshisa gravity incike into omkhulu, kanjalo Sun lesi silinganiso ifinyelela 273 m / s².

Ngemva kokuchitha ucwaningo lwakhe, Newton sinqume ukuthi amandla adonsela phansi umkhiqizo umzimba mass nokusheshisa, futhi washayelwa yakhe edumile ifomula F = m * g.

Kuyaphawuleka ukuthi, ngokusekelwe kule formula, kufanele kube: g = F / m. Lokhu kuveza nobukhulu ngokuba ukusheshisa gravity - ". Newton / kilogram" Lokhu ilebula ngokulinganayo "m / s²."
