32-8 Lorentz Transformation (LT) P747-749 (洛沦兹变换) Assume two inertial reference frames: S, S' O,o 'coincide’(重合 superimposed) at time:t=0 S为静系,S以υ沿ox轴向右运动(开始时,两 个坐标系原点重合)

32-9 Relativistic Momentum and Mass (P749-751) In classical mechanics, the law of conservation of momentum (P=constant) holds in different inertial reference frames. But in relativity, if we continue to define P=mv, and m is a constant, the total momentun is not conserved for different inertial frames

Chapter32 Special relativity(狭义相对论) Two Postulates(狭义相对论的两个基本假设) The relativity of simultaneity(同时性的相对性) The relativity of time(时间间隔的相对性) The relativity of length(长度收缩) The Lorentz Transformation(洛仑兹变换式) new look at momentum, energy(相对论质量
