Imithetho yesayensi, noma kungani zonke izinto awe phansi?

Kungani zonke izinto awe phansi lapho belahlekelwa isizinda sabo, futhi umuntu podprygnuvshy up, futhi emhlabeni? Impendulo yalo mbuzo itholakala endizeni imithetho eyisisekelo physics namandla adonsela phansi kuchazwe (ukuhumusha kusuka Latin - "ezisinda" kangaka, "isisindo") noma, ngamanye amazwi, ukukhangana yasemhlabeni, esakhiweni semvelo sawo ndaba. Ingqikithi zalesi simo itholakala lokuthi ukuthi yonke imigwamanda bakhangwa nomunye. Ngokwesibonelo, i-Earth amandla ayo adonsela phansi oqhubeka uqobo ngokuphelele konke: izihlahla, izindlu, abantu, amanzi, njll Ngenxa adonsela phansi sihamba, hhayi ngimuke esikhaleni universe.

Kuyini amandla adonsela phansi eMhlabeni, uma abakwazi ukubona noma uzizwe? Iqiniso lokuthi kuba interplay ibuthaka kuye ngokuthi ibanga phakathi kwezinto, kanye isisindo sabo. Uma isisindo into encane, amandla adonsela phansi yayo futhi, ngokufanelekile, kuyoba ababuthakathaka. Ngakho-ke, ukukhuluma ngezinto ezincane, singasho ukuthi engekho ngokuphelele. Ngisho umzimba omkhulu kangaka, efana ezintabeni, ukukhangana% 0,001 kuphela phezu komhlaba.

Nokho, uma sicabanga izinkanyezi namaplanethi amandla elanga adonsela phansi iba eziphathekayo ngenxa ubukhulu nesisindo yabo inkulu ngokuphindwe kaningi kunemali yini esizungezile. Futhi isizathu esenza zonke izinto esizowela phansi, ngenxa yokuthi nenqwaba Earth wethu kungaphezu indoda, noma nganoma isiphi esinye isikhungo. I Ngenxa yalokhu leaf bawa kuzoba phansi futhi akhangwe kunoma ukuma eduze emzimbeni. Nakuba-gravity kanye nokuphenyisisa ezimele ibanga (sisondelene izinto ahlelwe ukuze nomunye, namandla Luhambo zabo bobabili), nokho iplanethi mass kunomphumela elibaluleke kakhulu ngamandla adonsela phansi.

Manje kungase kuphakame umbuzo: kungani zonke izinto awe phansi, nenyanga - akukho? Lesi simo esiyingqayizivele sibangelwa alichaza yokuthi ngenxa ezinyakazayo njalo Zomhlaba bazungeza bedle gravity kugcinwa. Manje, uma inyanga yayimi, futhi akusho uphendukisa, kuba sengathi iyiphi enye into, nakho zizongena Ngokuhambisana nemithetho ngokomzimba.

Isimiso gravity global uvule uhlelo usosayensi oyiNgisi Newton. Yena waqala ukufakazela khona kanye nethonya kuwo wonke izinto universe. It is leli butho kwenza wonke amaplanethi ukuhambahamba ilanga, indoda - ukuhamba emhlabathini, futhi i-apula - bawe. umthetho wamandla adonsela phansi eMhlabeni (owaziwa nangokuthi umthetho wamandla adonsela phansi) uthi yonke imigwamanda lapho siqondiswa ukuba maphakathi emhlabeni ukuba izonikela ukusheshisa mahhala ukuwa. Ukutholakala kwaleli qiniso laba nethonya elikhulu ekuthuthukiseni of sciences ngqo futhi esintwini sisonke. Siyabonga kuye, ososayensi bayakwazi ukunquma ngokunemba okukhulu nenqwaba iziphuphutheki, amaplanethi kanye isikhundla kwezindikimba zasezulwini, amadivaysi othomathikhi bese trajectory of ukunyakaza kwabo esibhakabhakeni amashumi eminyaka ezayo. Lo mthetho uyachaza ukuthi kungani zonke izinto esizowela phansi, kungani kungekho amanzi Splashes out emkhathini, njengoba kukhona ukukhuphuka nokwehla. Ngaphezu kwalokho, kuvumela ukuba uthola yonke entsha, hhayi kuphela ngokubona, kodwa futhi ngosizo izibalo ezithile.
