Today, in modern education that places emphasis on knowledge and skills for new occupations of the 21st century, the teaching of physics has an increasing influence and importance. In this thesis, the emphasis is placed on early learning of physics, already in the lower grades of primary school. Numerous studies show that meeting children with STEM areas (science, technology, engineering and mathematics) is essential for their further interest and motivation towards these areas. Children at an early age are very curious, they ask a lot of questions and then it is the right time to introduce them to stimulating physical concepts. A key segment in physics teaching is experimentation. Experiments in physics teaching enable children to explore independently and encourage children's imagination, development of critical thinking and reasoning. Likewise, in modern physics teaching it is good to implement examples from everyday life that arouse additional interest in physics. Sport is a practical activity in which a number of physical laws are applied. To better understand them, there are two options, one is to investigate in detail - to measure movements and other physical phenomena in sports, and the other is to design and perform experiments to show the individual laws applied in sports. This thesis deals with several selected and adapted examples that can be implemented in the curriculum in primary school, mostly in the classroom teaching.
