电子的惯性质量随其运动速度的增加而变大:用电磁场使运动电子的运动轨迹偏转,测量其偏转的大小;只有把电子的荷质比(电荷与惯性质量之比)看成是速度的函数才能解释测量值;其它的实验分析显示电子的电荷与速度无关,因而得出惯性质量与速度有关的结论。这与牛顿力学中的“惯性质量是常数”的结论相抵触

电子的惯性质量随其运动速度的增加而变大:用电磁场使运动电子的运动轨迹偏转,测量其偏转的大小;结果表明,只有把电子的荷质比(电荷与惯性质量之比)看成是速度的函数才能解释测量值;其它的实验分析显示电子的电荷与速度无关,因而得出惯性质量与速度有关的结论。这与牛顿力学中的“惯性质量是常数”的结论相抵触





5. 伽利略相对性原理

伽利略相对性原理是说:力学定律在一切惯性系中均有效。这个原理表明,利用力学的方法不可能观测到绝对运动。牛顿力学第二定律在惯性系中写成:(其中是力,是物体的加速度,是物体的惯性质量)。相对性原理是说,在系中方程式具有相同的形式:(其中带“”的量是 系中的相应观测量)。更具体地说,经过伽利略变换后变成了,反之亦然。这个原理也显示:物体的惯性质量是个与运动速度无关的常数。另外,牛顿万有引力定律也满足伽利略相对性原理。
