通过对离心现象的认识,可以进一步加深对牛顿第三定律的理解。一、离心运动运用牛顿第三定律分析直线运动中的一些问题往往被认为是比较容易的事。但是,如何运用牛顿第三定律分析曲线运动中的一些问题就显得不是那么简单的了。如分析离心现象发生的原因,往往被错误地认为:①是由于物体不再受向心力,而只受离心力作用的结果;②是物体所受到的离心力大于向心力的结果。 By understanding the phenomenon of centrifugation, we can further deepen our understanding of Newton’s third law. First, the analysis of some problems in the linear motion using the Newton’s third law of centrifugal motion is often considered relatively easy. However, how to use Newton’s third law to analyze some problems in curve motion is not so simple. Such as the analysis of the reasons for the occurrence of centrifugal phenomenon, often mistakenly believed: 1 is due to the object is no longer subject to centripetal force, but only by the results of centrifugal force; 2 is the result of the centrifugal force of the object is greater than the centripetal force.
