Description
Technical Field
[0001] The utility model belongs to the technical field of small ball collision tests, in particular to a small ball collision test device. Background Art
[0002] The ball collision test involves suspending two small balls with strings of equal length. One ball is pulled up, then released, and allowed to collide with the other stationary ball. The stationary ball then begins to move after being struck, demonstrating that moving objects have energy and can affect other objects.
[0003] However, during actual operation, it was found that there was a certain degree of difficulty in assembling the entire set of instruments. For example, adjusting the two small balls to equal length would take some time and there would be certain errors. It was also difficult to make one of the hanging balls completely still. In addition, it was also difficult to make one of the hanging balls accurately hit the other hanging ball and move in the same direction after each collision. At the same time, the experiment could only judge the height to which the ball rose after each collision by the naked eye, and could not obtain specific height data through measurement.

In addition, it is also difficult to make one of the suspended small balls accurately hit the other suspended small ball and move in the same direction after each collision. At the same time, the experiment can only judge the height to which the small ball rises after each collision by the naked eye, and cannot obtain specific height data through measurement.
