The experience of objects falling down is something that the students learn at an early age, when they are only a few months old. They can determine the corresponding value of the acceleration due to gravity, among other things, in this topic area. In addition, experiments on uniform and accelerated motion on the roadway can be carried out. The impact tests can be used to carry out illustrative experiments and to work out topics such as momentum and its conservation, which form the basis for crash tests, for example. The mobile CASSY 2 WLAN and the light barriers M are used for all experiments.
