论文摘要
本文提出了一项建议，以将大学物理学第一课程的运动进行背景，以此作为对社会性质的决策的贡献。为此，考虑了使用动力学影响弹丸和官方资源提供的实际数据的情况。该信息用于描述球形弹丸的运动学特征（橡胶子弹）的对象运动模型。为了这些目的，使用了一个雷诺re >> 1，该雷诺允许使用非线性运动方程来找到弹丸的每单位面积的速度和冲击能量。该模型的结果和分析可以在课堂上引起一个有趣的讨论，内容涉及建立使用动力学影响弹丸的协议，以及在社会冲突中使用科学知识的重要性。
The article presents a proposal to contextualize the study of movement in first courses of university 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.
