舉例來說,當跳水者一離開跳水板的時候

他的身體是”一直不停的“變換位置來形成tuck position(跳水的一個姿勢)來讓身體的更快的轉圈

(見下圖)

angular velocity.

就像拉拉隊一樣,他們會做出翻滾然後形成jack-knife position(就是拉拉隊站好後要跳下來的形成的動作你應該看過吧).當身體沒有一個固定的地方,那就沒有辦法有一個穩定的axis(軸)來量他的angular velocity(角速度)

(見下圖後面在空中的那位)

第二個問題就是還要有方法來算出他們的轉動慣量(intertia)

越低的intertia, 轉的越快 (Fig.5 是指課本中的圖5)

兩張湯姆貓與傑利鼠數位影片的frame(就是一張一張的那個截圖)影射出掉的動作 他的肢體是一張一張的連續戳圖

After much wrestling with the problems and

經過一翻跟導師爭論以及討論的結果

兩組還是使用差不多的方法來進行

The analysis of the diving example

illu-minates the approach, which involves finding frame

sequences in which the diver is almost a rigid body.

跳水的分析照亮(指更樂觀)了這個方法,就是找出跳水者的連續戳圖,也就可以找出跳水者的靜止動作

In thefirst few frames after leaving the board, the diver is

rotat-ing slowly in a straight or pike position. A while later the

diver has curled up into a tuck position and is rotating

more rapidly (see Fig. 3).

在前幾張跳水者剛離開跳水板, 跳水者轉的很慢,形成直的或是pike position然後再過幾張戳圖後,跳水者變成tuck position然後轉得更快了 (見課本圖3)
