So, I'm going to illustrate the idea of kinematics by taking the simplest possible example.

所以我会用很简单的例子,来解释运动学

So the product of Newtonian mechanics of predicting the future given the present, has got two parts, and one is called kinematics and the other is called dynamics.

所以牛顿力学,基于现状对未来的预测,包含两个部分,一部分被称为运动学,而另一部分被称为动力学

If you want to describe this particle, what's the kinematics?

如果你想描述这个质点,如何从运动学角度来描述呢

耶鲁公开课 - 基础物理课程节选

In kinematics, you don't ask the reason behind anything.

在运动学中,我们不关心现象背后的原因

耶鲁公开课 - 基础物理课程节选

So, kinematics is a complete description of the present.

运动学是对现在的完整描述
