• Now, what we would like to do is we would like to convert all this gravitational potential energy into kinetic energy of that disk.

  现在要做的，就是要转化，所有这些重力势能，变成圆盘的动能。

• Comfort, potential energy and joint ranges of motion were set as constraints, as a result the posture prediction was more realistic.

  采用遗传算法来处理姿势预测问题，将舒适度、重力势能和关节活动范围作为约束条件，使姿势预测更加逼真。

• The object's potential energy of gravity is equal to the product of its weight and its height. The unit is J.

  物体的重力势能等于物体的重量和它的高度的乘积。单位是焦耳。

• Notice that the gravitational potential energy increases.

  注意，这里，重力势能是增加的。

• Let me first give you the formal definition of gravitational potential energy.

  我先给你一个对于，重力势能的形式定义。

• So you're using, then, the conversion of gravitational potential energy to kinetic energy.

  所以你在利用，重力势能，转换成，动能。

• When I'm here, gravitational potential energy ; increases in this way; the gravitational force is in this direction.

  重力势能，这样增长，重力；，是在这个方向，当我在这里。

• So this is a function y as a function of x and the curve itself represents effectively the gravitational potential energy.

  因此这是关于y的关系，曲线本身，很有效地代表了，重力势能。
