按牛顿运动定律适用性可以把描述物体机械运动的参考系分成两类:惯性系和非惯性系。即使在非惯性系中,通过引入相应的惯性力,仍然可以使牛顿定律在其中保持“形式上”的适用。以牛顿运动定律为基础,进一步完善和发展成的经典力学可适用于大至行星天体运动,中至行车、使船和火箭发射,小至分子、离子的运动。
According to Newton’s Law of Motion Applicability The reference frame describing the mechanical motion of an object can be divided into two categories: inertial and non-inertial. Even in non-inertial systems, it is still possible to adapt Newton’s law to “formal” by introducing the corresponding inertial forces. Based on Newton’s law of motion, the classical mechanics further refined and developed can be applied to the astronomical movements of the planets, moving from mid-to-long traffic, making ships and rocket launches, and small molecules and ions.
