那就让我们用另一个表达式来表示弹簧的收缩距离。

Let me get another expression for the spring compression.

有上述公式可知，加速度取决于弹性系数和弹簧(即汽泡纸)收缩的距离。

So the acceleration depends on the value of the spring constant as well as the distance the spring (bubble wrap) is compressed.

不过，当肌肉做短距离收缩的时候，它们移动更慢，产生的力量更大。

When contracting short distances, though, they move more slowly and generate more force.
