Of course, experimentation is important to learner training. They sometimes understand the laws of physics by feeling on their skin and see them in real action.Eksperiment should be simple to understand, because complex things do not always remain in good memory. In general, the following experiments that are realized in real life, are better. There were no need such explenation on the kinetic and potential energy of the essence in this experience, but rather to explain how this experiment remains in the memory of students and whether they are well aware of the level of theory.

The exercise is a good example of the transition of potential into kinetic energy, but having a bounce of a height 9 times and 49 times larger than the original one is not understandable by the description. I assume that the balls are with very different masses and thus these numbers are estimated. I tried to do the experience myself but it did not work. May be if you can share more details of how exactly you are performing it, or post a picture it will be more easily understandable by other teachers. I think for a young physics teacher, who has never done an experiment with students in class it will be impossible to do that experiment.

Experiences are easily achievable in the classroom, because the materials used are easily obtainable and the cost is very low. Whenever practical examples help to understand the theoretical concepts, and from this point of view, both experiences are applicable to explain both phenomena. If we consider these experiences relevant to explain these physical phenomena.
Students wake them forward to conducting this type of practice, the problem is that you can’t always use practical examples to explain all physical phenomena, although this is not the case. It is a possible solution to the lack of student motivation. In past courses while teaching Physics I made a similar experience to that detailed in the first experience, and currently I teach specialty chemistry.
