谈谐振子周期公式的正确理解和使用

Correct Comprehension and Use of the Period Formula on Harmonic Vibration Particle

物理公式往往有其成立条件和适用范围,学习物理概念、定律、公式应重在对其物理意义的理解。单摆周期公式T=2πl/g就存在“陷阱”,一不小心容易“掉”进去,试讨论它在于给大家一个标识,以免踏入“误区”。

The physics formulas usually have their tenable terms and applicable scope. Importance should be attached to the comprehension of physics meaning in the study of physics concepts, laws and formulas. There exists a ＂trap＂ in the single pendulum period formula T=2π√l/g. This thesis discusses it in order to show a mark, preventing steps into the ＂mistaken area＂.
