Item Motion analysis of kinetic impact projectiles for physics education in real context(2020-04-16) Hernández, Carla V.; Echiburu, Mauricio A.; Humire, Fernando R.; Mosso, Edward F.The article presents a proposal to contextualize the study of movement in first courses of univer- sity physics, as a contribution to decision-making in situations of a social nature. For this, the case of the use of kinetic impact projectiles and the actual data provided by official sources is considered. This information is used in an object motion model describing the kinematic characteristics of a spherical projectile (a rubber bullet). For these purposes, a number Reynolds Re ≫ 1 was used, which allows applying a nonlinear motion equation to find the velocity and impact energy per unit area of projectile. Results and analysis of this model can generate an interesting discussion in the classroom about the need to build protocols for the use of kinetic impact projectiles, and the importance of using scientific knowledge in social conflicts.
