Most teachers of physics who teach mechanics at all levels of education make use of the traditional blocks to teach the laws of statics and dynamics. More complex movements like the ones of human body in jumps, kicks or throws are left out of this analysis. We propose a simplified way to analyze these movements through some basic concepts taught in traditional mechanics courses, especially the center of mass. In this approach, we begin with the study of particles, proceed to rigid bodies (which include the blocks) and then to the basic movements of the human body in some sports. Thus, we expect that the study of mechanics becomes more pleasurable and contextualized, as we have seen in lectures and courses. Given the breadth of the subject, we prefer to divide the article into topics. In this first article, we clarify the theoretical analysis and treat jumps in some collective sports.
