中学阶段有关牛顿的力学规律在使用时一般是以地面为参考系的,那么在运动的惯性系和非惯性系中应如何使用这些力学规律呢?下面就这个问题作一探讨.一、运动的惯性系中的力学规律由于在所有的惯性系中遵循相同的物理规律,也就是说所有的惯性系是等价的.所以,在运动的惯性系中各类运动学公式、牛顿运动定律、动能定理、动量定理、机械能守恒定律、动量守恒定律都是成立的,只不
Middle School stage on the Newton’s laws of mechanics in use is generally based on the ground as a reference system, then in the inertial and non-inertial system of motion should be how to use these mechanical laws? Here’s a discussion of this issue. Mechanics laws in inertial systems Since all inertial systems follow the same physical laws, that is, all inertial systems are equivalent, various kinematic formulas, Newton’s laws of motion, kinetic energy Theorem, the theorem of momentum, the law of conservation of mechanical energy, the law of conservation of momentum is established, only
