[請益] 剛體動力學：功與能和角加速度

1^F推ntust661:(3). 只要知道力矩和等於零就好01/24 08:40

2^F推ntust661:(2). 這種就要歸功能原理啦01/24 08:44

3^F→ntust661:mgh = 1/2 mv^2 可以求出碰撞前速度大小01/24 08:45

4^F→ntust661:m1v1 + m2v2 = (m1+m2)V 算出碰撞後速度大小01/24 08:45

5^F推ntust661:列出事件，一開始彈簧早就被壓縮了01/24 08:47

6^F→ntust661:所以事件發生前，有重力位能與彈性位能01/24 08:48

7^F→ntust661:事件發生後，損失了一些能量，剩下彈性未能01/24 08:48

8^F→ntust661:彈簧壓縮這種題目，重力位能要考慮h + δ01/24 08:50

9^F推ntust661:最後一題出的有瑕疵，他沒說他純滾動01/24 08:55

[請益] 對偶中的滾動對一問
