铅球投掷演示仪设计与最佳投掷角度研究

Shot Put Demonstrator Designing and Research on the Best Throwing Angle

依据物理和数学原理结合教学实际设计了铅球投掷演示仪 ,使学生能够清楚地看出出手角度、高度和投掷力量对投掷距离的影响 .同时 ,也探讨了不同条件下的最佳出手角度 .

This text deals with designing a shot put demonstrator on the principles of physics and mathematics,enabling students to be aware how their throwing angles,heights and strength affect their throwing distance,and their best throwing angle in different conditions.
