关于相对论质速公式的推导,常见的方法是建立爆炸[1]或碰撞[2-3]模型,再利用动量守恒和洛伦兹速度变换,便可顺利地得到m(v)=m01-v2c2.我校为数理能力特别强的学生专门开设了《荣誉物理》选修课,在这门选修课的教学中,笔者曾经围绕质速公式的推导组织了一次Seminar研讨,有位学生意外地发现了质速公式推导中的一个矛盾.
A common method to derive the formula for the relativistic mass velocity is to establish a model of explosion [1] or collision [2-3], and then use the conservation of momentum and the Lorentz velocity transformation to obtain m (v) = m01-v2c2 In our teaching of elective courses, the author organized a seminar seminar on the derivation of the rate of mass formula, and one student unexpectedly discovered A contradiction in the derivation of mass velocity formula.
