【科學不設限】EP.002 人口「加速度」轉負,台灣的未來將走向何方? 運動學中的位移、速度與加速度,不僅能解釋物理現象,還可用來分析其他領域的趨勢,例如人口變化。 速度代表變化的趨勢,加速度則反映趨勢的改變。 以台灣少子化為例,人口成長率相當於速度,表示人口增減的變化。 自20世紀末起,雖然人口數仍增加,但成長率逐年下降,顯示趨勢逐步放緩。 2020年人口成長率首次為負,總人口開始減少。這過程如同減速的車輛,雖然仍前進,但最終會停下甚至倒退。 運動學的分析方法不僅適用於科學,也能解讀社會變化與未來趨勢,幫助我們應對挑戰。 學好運動學,就能成為看懂趨勢的專家! #臺灣人口 #加速度 #人口成長率 -- Hosting provided by SoundOn
