实验结果表明,人造触手能将一个物体包裹起来,其运动方式与真章鱼有着惊人的相似之处。
The result can wrap itself around an object with a movement that strikingly resembles that of the original.
物体或物体系的总动能等于每种运动方式的动能之和,取决于质量和速度。
The total kinetic energy of a Body or system is equal to the sum of the kinetic energies resulting from each type of motion. The kinetic energy of an object depends on its mass and velocity.
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
