普通高中新课程标准实验教科书《物理》(必修)第六章第3节“探究平抛运动的规律”一节,对平抛运动水平方向分运动的研究与已往教材相比有很大的改进,是引导学生通过实验途径进行科学探究的好内容.在已知平抛运动竖直方向做自由落体运动的前提下,教材39页给出了“三步走”的研究思路:实验获 Ordinary high school curriculum standard experiment textbook “Physics” (required) Chapter 6 Section 3 “inquiry into the law of flat throwing motion ” section, research on horizontal throwing movement in horizontal direction is very large compared with previous textbooks The improvement is to guide students through the experimental way to carry out scientific exploration of good content. In the known flat-throw motion vertical free-fall movement under the premise of the textbook page 39 gives the “three steps” research ideas: Experimental gains
