对D.库尔茨关于牛顿第二定律讲解法的商榷

On Questioning of D. Kurtz’s Explanation of Newton Second Law

牛顿第二定律在中学物理教学中既是讲解重点又是讲解难点,本文认为著名学者D.库尔茨提出的将F=ma改写成a=F/m的讲解法存在商榷,从该公式中对等号的正确理解、从公式的实际应用、从力与质量概念的逻辑发展三个方面分析,牛顿第二定律最适宜的表述形式应为F=ma。

The Newton Second Law is the key content point as Tell as the difficult one in the middle school physics teaching. 1 propose the different view on the idea that D. Kurtzsay F=ma can be rewritten a=F/R. This article narrates the most suitable form of the Newton second law is F=ma from three aspects.
