Zamkati
Pulogalamu yamphamvu yokoka Ndi chimodzi mwazinthu zofunikira kwambiri zomwe zimayang'anira chilengedwe chonse komanso zomwe zimapangitsa zinthu ndi zamoyo kukhalabe zolimba padziko lapansi, chifukwa chokopa kupita pakati pa Dziko Lapansi.
Kumbali imodzi, mphamvu yokoka imatha kufotokozedwa ngati gawo lamphamvu yokoka yomwe imagwira ntchito pamatupi akulu, ndikuwakopa. Komano, ndizofala kunena za mphamvu yokoka monga kuthamanga komwe matupi amakopeka ndi Dziko Lapansi. Kuthamangitsaku kuli ndi pafupifupi mamitala 9.81 pa sekondi imodzi.
Ngati mphamvu yokoka ikadakula, zinthu zogwa mwaulere zimatenga nthawi yocheperako kuti zifike pansi ndipo kuyenda kwathu, mwachitsanzo, kumakhala kovuta kwambiri. Kumbali ina, zikadakhala zochepa, timayenda ngati kuyenda pang'onopang'ono, chifukwa zimatenga nthawi yochulukirapo kuti phazi lililonse libwerere pansi. Izi zidawonekera pomwe oyenda m'mlengalenga amayenda pa Mwezi pomwe mphamvu yokoka ndiyochepa.
Chifukwa cha geometry ya Dziko lapansi, pamiyala mphamvu yokoka imakhala yayikulu kwambiri (9.83 m / s2) ndipo mdera la equatorial ndiyotsika pang'ono (9.79 m / s2). Mphamvu yokoka ya Jupiter ndiyamphamvu kwambiri kuposa dziko lathu lapansi, pomwe a Mercury ndi ofowoka kwambiri.
- Onaninso: Vector ndi scalar kuchuluka
Akatswiri ofufuza mphamvu yokoka
Chifukwa cha zovuta komanso zovuta kusanthula, kuphunzira za mphamvu yokoka kudapatula asayansi ofunikira kwambiri amunthu. Malinga ndi nthawi, Aristotle, Galileo Galilei, Isaac Newton ndi Albert Einstein ndi omwe adathandizira pazofunika kwambiri pankhaniyi.
Mosakayikira awiri omalizirawa amaonekera, woyamba kupereka ubale pakati pa kukopa kwachikondi potengera mtunda wapakati pazinthu zomwe zakopedwazo ndi unyinji wawo, pomwe wachiwiri ndi amene adapeza kuti zinthuzo ndi danga zimagwirira ntchito limodzi, zinthu zosokoneza malo , umene umatulutsa mphamvu yokoka. Malingaliro onse awiriwa adapangidwa kwambiri pogwiritsa ntchito masamu ndipo masiku ano amawerengedwa kuti ndi amodzi ofunikira kwambiri m'mbiri ya sayansi.
Zitsanzo za mphamvu yokoka
Mphamvu yokoka imachitika nthawi zonse. Nazi zitsanzo zina zomwe zikuwonetsa:
- Ntchito yosavuta yoimirira kulikonse ndi chifukwa cha mphamvu yokoka.
- Kugwa kwa zipatso za mitengo.
- Mathithi akulu agwa.
- Gulu lotanthauzira lomwe mwezi umapanga kuzungulira dziko lapansi.
- Mphamvu yomwe iyenera kugwiridwa mukakwera njinga kuti musagwe.
- Mvula imagwa.
- Zomangamanga zonse zomwe anthu amapanga zimakhalabe zoyimirira komanso pamtunda chifukwa cha mphamvu yokoka.
- Kutsika kumene thupi limadutsa likaponyedwa mmwamba ndi chifukwa cha mphamvu yokoka.
- Kuyenda kwa pendulum, ndi mtundu uliwonse wa mayendedwe a pendulum.
- Kuvuta kudumpha kulemera kwambiri komwe munthu ali nako.
- Malo osangalatsa osangalatsa.
- Kuuluka kwa mbalame.
- Ulendo wa mitambo kumwamba.
- Pafupifupi masewera onse, makamaka kuwombera hoop ya basketball.
- Kuwombera kwa projectile iliyonse.
- Kufikira ndege (pomwe mphamvu yokoka imalipidwa pang'ono ndi mphamvu yokweza.).
- Mphamvu yomwe iyenera kuchitidwa mutanyamula china cholemera ndi thupi.
- Zizindikiro zakukula, ndiye kuti, kulemera kwa thupi, sizoposa kulemera kwake chifukwa cha mphamvu yokoka.
- Pitirizani ndi: Kugwa kwaulere ndi kuponya mozungulira
