# 重力加速度实验报告 **一、实验目的** 1. 掌握秒表、米尺等测量工具的正确使用方法。 2. 深入理解单摆法和落球法测量重力加速度的原理。 3. 探究单摆振动的周期与摆长、摆角之间的关系。 4. 学会系统误差的修正以及在实验中减小不确定度的方法。 **二、实验器材** 单摆装置、停表（精度为0.01s）、钢卷尺（精度为1mm）、游标卡尺（精度为0.02mm）。 **三、实验原理** ## （一）单摆法 单摆由一根不可伸长的轻质细线和下端悬挂的体积小、质量大的重球组成。在摆长远大于球直径且摆球质量远大于线质量的条件下，将小球自平衡位置拉至一边（摆角小于5°）后释放，摆球会在平衡位置左右做周期性往返摆动。 摆球受到的力为重力和绳子张力的合力，当摆角很小时（5°），可近似看作简谐振动。设摆长为L，小球位移为x，质量为m，根据牛顿第二定律和简谐振动公式可得单摆运动周期公式\(T = 2\pi\sqrt{\frac{L}{g}}\)，即\(g=\frac{4\pi^{2}L}{T^{2}}\)。但由于细线有质量且不完全不可伸长，实际的重力加速度公式需修正。 ## （二）落球法（参考资料未详细提及落球法的实验原理推导，可补充理论知识进行完善） 根据自由落体运动公式\(h = \frac{1}{2}gt^{2}\)（h为下落高度，t为下落时间），在忽略空气阻力的情况下，通过测量物体下落高度h和下落时间t，就可以计算出重力加速度\(g=\frac{2h}{t^{2}}\)。 **四、实验步骤** ## （一）单摆法 1. **数据采集**...
