Wind as a context for Newton’s first and second law and force diagrams

Abstract Teachers commonly use examples that omit friction to teach Newton’s first and second law. Beyond the motion of planets, the flow of horizontal high-altitude winds along the isobars presents a real-world motion scenario with negligible friction. This natural phenomenon serves as an applicable context for the exploration of Newton’s first and second axioms and the vector addition of forces. This paper explores wind dynamics as a context that addresses force concepts, a relevant topic in high school physics. Here, we focus on forces affecting air parcels at high altitudes. For comparison, we also explain the wind at ground level (called surface wind), where friction plays an important role. We aim to elucidate the complexities of wind forces, offering a comprehensive understanding of how these forces interplay in real-world scenarios. Furthermore, we provide detailed examples of tasks for high school students to acquire an understanding of wind and aligning forces.
