摘要:研究了在大角度下阻尼对单摆周期的影响,提出了每个周期值T与对应周期序数n的关系,总结出T与n间近似的线性变化规律;得到了连续摆动32个周期后,其角度变化Δθ值与初始角度θ0的关系式.
The influence of damping on the period of wide-angle simple pendulum was studied in this paper. A linear relationship between period and ordinal number was proposed. The relationship between the changes of the angle after 32 continued periods with the initial angle was obtained from the experimental data.
