〈EP.42|牛頓的思想實驗〉

16 Jun 2025

Description

本節目提到,牛頓透過思想實驗,想像站在高塔上扔石頭,發現石頭的拋物線運動是由水平與垂直兩種運動合成,並進一步思考,若石頭扔得夠快,地球是圓的,石頭將會一直繞著地球轉,因而提出了引力的概念,認為此力可以隔空作用且指向地球球心,並將其比喻為甩動鏈球時手施加的牽引力,從而解釋了生活在地球「下面」的人不會掉下去的原因。 Music from #Uppbeat (free for Creators!): https://uppbeat.io/t/augustine/happy-thoughts* (https://click.pstmrk.it/3s/uppbeat.io%2Ft%2Faugustine%2Fhappy-thoughts/vZub/Mhq9AQ/AQ/9a81cc98-33e3-4393-988c-e260893fbecf/4/dtHb1EMCam)* License code: 8OVD4G7T97U9LV7C Music from #Uppbeat (free for Creators!): https://uppbeat.io/t/augustine/morning-delight* (https://click.pstmrk.it/3s/uppbeat.io%2Ft%2Faugustine%2Fmorning-delight/vZub/Xxq9AQ/AQ/ca281cb2-e180-44ce-940b-77e13433f497/4/LsEyUh3NZJ)* License code: TWE91SVFFA9Q2WDW -- Hosting provided by SoundOn
