答案是地球运动的动力学,顺便说一下,这也是导致冰河时代的原因。
The answer is the dynamics of earth's motions, the same thing that caused the Ice Age by the way.
任何严肃的教育理论都涵盖两个部分:对生活目标的理解和心理动力学的知识,即精神运动的规律。
Any serious educational theory must consist of two parts: a conception of the ends of life, and a science of psychological dynamics, i.e., of the laws of mental change.
现代运动用滑翔机的机翼长而细薄,拥有最佳的空气动力学效率,其升阻比达到50:1。
A modern sports glider, with long, slender wings, is the most aerodynamically efficient aircraft, with a lift-to-drag ratio of around 50:1.
You simply want to describe things the way they are and then dynamics tells you how they changed and why they changed.
你只是单纯描述物体的实际状态,而动力学则是解释它们运动的方式和原因的
And so, you know from your Newtonian mechanics, as you were learning in 8.01, the dynamic force here mv^2/r is mv squared over r.
在8。01节对牛顿动力学系统的学习中,我们可以知道这里的运动受力,就是。
