摘要
介绍了利用多次曝光法研究小球的抛射体运动，设计了实验装置．通过用表差法处理实验数据，从而探索抛射体的运动规律并求得重力加速度值．通过对实验的误差分析，给出了结果的不确定度评定．
The projectile motion of a small ball is studied by repeated exposure,and the experimental device is designed.Through treating a set of data by using the tabular differences method,the motion law of the projectile is obtained and the gravitational acceleration is solved.Through analysing the experimental error,the gravitational acceleration uncertainty is given.
