Precise Equation and Numerical Solution of Optimal Throwing Angle of Solidball

体育运动与物理知识息息相关,其中以力学定律为主.以体育运动为载体的物理问题具有很强的实用性,物理知识对于解决和提高体育运动中的实际问题具有广泛的指导意义.物理教学中应注意培养学生分析解决实际问题的能力,提高学生的综合素养.本文就中考体育实心球项目中的物理模型进行研讨,指出关于实心球最佳投掷角计算公式中存在的问题,导出了最佳投掷角的精确方程和数值解,对提高项目分数具有指导意义.

Sports are closely related with the knowledge of physics, in which the law of mechanics is the main. The physical carrier in sports has a strong practical, physical knowledge has a wide range of guiding significance to solve and improve the practical problems in sports. We should pay more attention to the ability of students to analyze and solve practical problems and improve the students＇ comprehensive accomplishment. In this paper, we discuss the physical model in the solid ball project, and point out the problems in the formula of the optimal throwing angle of the solid ball. The precise equation and numerical solution of the optimal throwing angle of solid ball are derived, which is of great significance to improve the project score.
