通过分析动量定理、流体力学、物态变化在物理学中的应用,以及球场方向设置的物理原理和足球运动在物理试题中的体现,说明物理原理与足球运动联系紧密,二者是理论与实践的关系,运用物理学原理可以指导足球训练与比赛,反过来足球运动又为物理研究提供素材。 Through the analysis of momentum theorem, fluid mechanics, the application of change of state in physics, and the physical principle of the course setting and the manifestation of football in the physical examination, it shows that the physical principle is closely linked with football, both of which are the theory and practice The relationship between the use of principles of physics can guide the football training and competition, football in turn provide material for physical research.
