Mawu Oyamba: Nthano Ya Amphaka Nthawi Zonse Imatera Pamapazi Awo

Amphaka amadziwika kuti ali ndi mphamvu komanso amatha kutera, koma kodi izi ndi zoona? Lingaliro lakuti amphaka amatha nthawi zonse kumapazi awo ndi nthano yotchuka yomwe yakhalapo kwa nthawi yaitali. Ngakhale zili zowona kuti amphaka ndi aluso kwambiri pakutera pamapazi, sangathe kutero nthawi zonse. Ndipotu, kugwa kungakhale koopsa kwa amphaka ndipo kungayambitse kuvulala koopsa, ngakhale imfa.

Physics of Cat Falls: Kumvetsetsa Angular Momentum

Kuti mumvetsetse momwe amphaka amatha kutera pamapazi awo, ndikofunikira kumvetsetsa lingaliro la kuthamanga kwa angular. Mphaka akagwa, amatha kupotoza thupi lake mkati mwa mpweya, zomwe zimathandiza kuti akhazikitsenso mapazi ake pansi pa thupi lake. Izi zimadziwika kuti cat's righting reflex, ndipo ndi luso lofunika kwambiri lomwe limalola amphaka kuti asavulale akagwa. Thupi la mphaka limathanso kutenga mantha a kugwa, zomwe zimathandiza kuchepetsa ngozi.

Komabe, kutha kupotoza ndikuyikanso thupi lake sikopanda malire, ndipo pali malire a cat's righting reflex. Izi zikutanthauza kuti ngati mphaka wagwa kuchokera pamtunda waukulu, sangathe kupindika ndikuyikanso thupi lake panthawi yake kuti agwere pamapazi ake. Kuphatikiza apo, malo omwe mphaka akugwera amathanso kukhudza kuthekera kwake kutera bwino. Zinthu monga kutalika kwa kugwa, pamwamba pomwe mphaka akugwera, ndipo mmene thupi lake lilili, zonsezi zimathandiza kudziwa ngati mphaka atha kutera pa mapazi ake kapena ayi.
