| Abstract: | 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. |
