※ 引述《balahaha (小妹哥)》之銘言： : 第二是在男主角放開繩索那段 : 我怎麼想都覺得動量在兩人運動行為一停止那一瞬間已經抵銷掉了也就是腳勾到那瞬間 : 男主角到底受了哪裡的力一直要往後飛(抖 : 女主角只要好好小心用腳施力應該是不用輪到男主角自爆的反正又沒別的力在阻擋 : 看他們在這大問號上拉拉扯扯依依不捨讓我忍不住出戲了 : 這麼重要的劇情轉折點建立在不穩的基礎上也很難對之後延伸的劇情有共鳴簡單的說兩力要完全相消物體才會真正停止喬治的人飛離太空站珊卓被降落傘繩扯住停下來然後這時珊卓拉住喬治的安全繩試圖停下他的運動狀態但很明顯的兩方的繩索(安全繩與降落傘繩)都處於繃緊狀態這證明了喬治的飛離動能還未完全消滅因為僅僅是靠著珊卓腳上的降落傘繩纏住的摩擦力去消減而看得出傘繩因為摩擦力不足而逐漸脫離珊卓的腳如果喬治不放開安全繩那就是賭他的飛離動能與傘繩摩擦力何者先消耗完畢摩擦力消滅那就兩個人脫離太空站完蛋了順帶一提太空裝約120kg 而艙外推進器(MMU)重量也有130kg 也就是說背了推進器的喬治大約比珊卓多了150kg的質量以物理角度來說動能很難靠摩擦力抵消參考一下 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 175.96.165.74

推 balahaha:電影中是已經"停止"一段時間了(十秒) 照理說動能早沒了 10/09 17:55

→ k1a1t1a1n1a:停止是兩力持續拉扯的狀態證明力量未消滅完成 10/09 18:00

推 celex:我看的感覺並沒有停止,腳上的繩索不斷拉扯鬆脫,也可能我腦補 10/09 18:00

→ k1a1t1a1n1a:宇宙中沒有地心引力幫助物體自動停下 10/09 18:00
