Mphamvu ya centrifugal kuti: ndichiyani ndipo kodi ntchito?

Monga amadziwika, khalidwe lililonse la thupi kukhala uliri kupuma kapenanso yunifolomu rectilinear zoyenda bola sati anapanga zimakhudza aliyense kuchokera kunja. Mphamvu ya centrifugal wa - ichi sichina koma kusonyeza chilengedwe lamulo la inertia. Mu moyo wathu, amapezeka pafupipafupi kuti ife pafupifupi osaganizira ndi anatani pa mlingo chikumbumtima.

maganizo

Mphamvu ya centrifugal ndi - ndi mtundu mmene mfundo thupi mphamvu ya fetter ake ufulu kuyenda ndi kukhala muyenda curvilinearly wachibale kumanga thupi lake. Chifukwa kusamutsidwa vekitala a thupi amasintha mosalekeza, ngakhale choncho kumene liwiro lake mtheradi amakhalabe zikutsatiridwa, phindu mathamangitsidwe si wolingana ndi ziro. Choncho, chifukwa cha lamulo lachiwiri Newton, umene inakhazikitsa kudalira pa mphamvu pa misa ndi mathamangitsidwe wa thupi, pali mphamvu centrifugal. Tsopano, kumbukirani ulamuliro wachitatu wa sayansi wotchuka British. Malinga ndi iye mu chikhalidwe cha mphamvu alipo awiriawiri, choncho, mphamvu centrifugal tiziligwirizanitsa ndi chinachake. Ndipotu, payenera kukhala pali chinachake woyang'anitsitsa thupi pa njira yake yokhota kumapeto! Ndi, mu tandem ndi kupota centrifugal pa chinthu ngati centripetal mphamvu zochita. Kusiyana pakati pa iwo ndi kuti oyambawo Ufumuyo thupi, ndipo chachiwiri - kuti kugwirizana ake ndi mfundo padziko limene kasinthasintha amapezeka.

zimaonekera pamene centrifugal mphamvu

Izo ziyenera falitsani yaing'ono dzanja kulemera kuti Ufumuyo twayini atangomaliza ayamba nkhawa za zingwe. Ngati panalibe mphamvu zotanuka, chikoka cha mphamvu centrifugal kungachititse kuti chotupa a chingwe. Nthawi iliyonse ife kusuntha panjira zozungulira (njinga, galimoto, sitima, etc.), ife mbamuikha zosiyana kuchokera kasinthasintha malangizo. Choncho, mayendedwe mkulu-liwiro m'madera zolimba zokhotakhota njira ali ndi ndingaliro wapadera opatsa wamkulu bata kupikisana racers. Tiyeni tione chitsanzo china chidwi. Chifukwa lathuli imazungulira ngati nguli, mphamvu centrifugal amachita pa zinthu zonse, zomwe zili pamwamba pake. Choncho, zinthu zonse kukhala zosavuta. Ngati inu kutenga thupi la 1kg ndi kusuntha izo kuchokera kumpoto kwa equator, kulemera kwake yafupika ndi magalamu 5. Ndi mawu zinthu sizinasinthe, chochitika ichi zikuwoneka ogwirizana. Komabe, ndi kuwonjezeka thupi kusiyana kumawonjezera. Mwachitsanzo, nthunzi sitima anafika ku Odessa ku Arkhangelsk, zikanakhala bwino pa makilogalamu 60, ndipo pa nkhondo yolemera matani 20,000, ulendo wake ku White Nyanja Nyanja Black, simudzavutika ndi matani 80! Zachitikiranji zimenezi? Chifukwa mphamvu centrifugal opangidwa ndi kasinthasintha wa dziko lathuli, amamuchititsa kumwaza padziko lapansi, ndi zonse izo ziri. Kodi Mzimuyo kufunika kwa mphamvu centrifugal? Kachiwiri, kumbukirani ulamuliro yachiwiri Newton. The chizindikiro choyamba kuti umakhudza ukulu wa mphamvu centrifugal, ndithudi, ndi unyinji wa thupi onsewo. A chizindikiro chachiwiri - mathamangitsidwe, imene curvilinear zoyenda amadalira mathamangidwe rotational ndi utali wozungulira wa thupi anafotokoza. ubwenzi akhoza kuwonetsedwa mu mawonekedwe a chilinganizo ndi: a = v ² / R. Analandira: F = mamita * v ² / R. Asayansi amati ngati Earth wathu imazungulira kamodzi 17 msanga ndiye equator idzakhala ndi kulemera kwake monga ngati kusintha wathunthu chinakwaniritsidwa mu ola limodzi lokha, kuwonda kukanakhudza osati pa equator, koma nyanja onse ndi maiko, amene ali pafupi ndi izo.
