now, that is only for a point mass.

那只是对于一个质点而言的。

the compliant surface (the springboard) is modeled by a rigid bar with a rotational spring on the hinged end and point mass on the tip.

弹性表面（跳板）由板端为等效质点，另一端为转动式弹簧之刚体所模拟。

case in point: mass effect 2, which came out in january and sold more than 2 million units in its first week of release.

准确例子：质量效应2，一月份发布，发行第一周销量超200万套。

newton's law of motion as applied to the point mass is the well-known vector equation: f=ma.

牛顿运动定律应用于质点时就得到这样一个著名的向量方程式：

the center of mass of a system is defined as follows: i have here some kind of an object not just a point mass, but it has a finite size.

系统的重心，是这样定义的：，我有一个物体，不是有棱角的物体，但它大小有限。
