Abstract des Autors

From the theoretical point of view of physics, the act of being and moving in a fluid medium, such as water, is a complex event. When attempting to explain phenomena related to this situation, teachers are often faced with difficulties in comprehension. With this fact in mind, we have to ask ourselves how a student should be able to comprehend and visualise the physical properties of water. Presenting a comprehensible set of hydrostatic and hydrodynamic experiments in the classroom setting of advanced high school students specialised in physical education is a formidable task. Despite the fact that the physical conditions in water seem to be covered adequately in various textbook illustrations, the actual grasp of the concepts remains elusive. This is the reason why many teachers are reluctant to cover such topics in the classroom. The purpose of this study was to demonstrate simple experiments in physics to enhance the understanding of the physical foundations of propulsion concepts pertaining to the dynamic lift and the Magnus-effect.
