【摘要】 在普通物理实验中大都测量物理常数,实验内容基本属于对物理学定律进行检验。然而,实验不仅可以验证物理规律的正确性,而且还可以通过实验总结归纳,得到物体的运动规律。该文利用焦利秤研究弹簧振子,通过观察弹簧振子的运动,找到弹簧振子周期与其它物理量之间的数量关系,从而总结出弹簧振子的运动规律。更多还原

【Abstract】 In many general physics experiments,in addition to learning how to use the basic experimental apparatus,students often measure physical constants and verify the fundamental physical laws established previously.However,experiments can be utilized not only for verifying the fundamental physical laws,but also for actually deducing them.This paper illustrates how to establish a theory based on experimental observations,with the motion of a spring oscillator as an example.Through observing the motion of a spring oscillator,we first found the relationship between its period and other physical quantities,and then deduced the general law that governed its motion.更多还原
