摘要
通过对飞机上螺旋桨运动学问题的一题多解,具体展示了求解点的合成运动问题的主要方法,并剖析其特点,旨在通过“一题多解”开阔思路,强化学生多角度分析和灵活解决问题的能力,启迪创新思维,促进科学思维能力的发展,提升核心素养.
Three different methods are as an illustration applied to a typical case of aeroplane propeller, to solve the kinematics of a moving point of a rigid body in the general motion. And the characteristics of various solutions are discussed. By means of multi-solutions to a problem in physics learning, students can benefit more as to improve their problem-solving skills, develop their scientific thinking abilities and inspire their creative thinking as well.
