由于高速运动与日常生活的低速运动相距很远,《相对论简介》中关于同时的相对性的问题同学们很难理解,多数同学是凭借运气——猜测;少数同学的方法更大胆,先自己分析一个答案,再用恰好相反的思想得到正确答案.这种作法把科学变成了玄学,如果我们能画出三个系(三个系分别为静止系、运动系、相对系),求解同时的相对性就有规律可循.下面举例说明.例1一列火车在平直的轨道上飞快地匀速行驶,车厢中
Because high-speed exercise is far away from low-speed exercise in daily life, it is difficult for students to understand the issue of simultaneous relativity in the Introduction to Relativity. Most of the students rely on luck - guess; the method of minority students is more daring, An answer, and then the correct answer to the opposite idea, which turns science into metaphysics, and if we can draw three lines (three lines are static, kinematic and relative) The relative nature of the law to follow. Example below. Example 1 A train on a straight track fast and uniform speed, the car
