在动量守恒定律的实验中,小球在记录板上的记录点有三个,确定哪个点是入射球碰前的落点,哪是入射球碰后的落点,哪个又是被碰球碰后的落点,是解决本实验相关问题的关键。现把小球落点位置确定及相关问题归纳如下:
In the experiment of law of conservation of momentum, there are three recorded points on the record board to determine which point is the landing point before the incident ball, which is the landing point after the incident ball is touched and which is touched by the touched ball Is the key to solve the problems related to this experiment. The location of the ball is now to determine the location and related issues are summarized as follows:
