近年来,高考物理试卷中出现了一些立足于课本知识,着眼于高新科学技术的试题.一方面检测了学生联想、迁移、分析、综合等能力,另一方面也可使学生明白高新科学技术并非空中楼阁,神奇非凡.下面结合近几年高考题的解析来谈谈这个问题. 一、飞船运行问题 例1(2001年广东、河南卷)无人飞船“神州二号”曾在离地面高为H=3.4×105m的圆
In recent years, there have been some examination papers based on textbook knowledge and high-tech science and technology in college entrance examination physics papers. On the one hand, students’ ability in association, transfer, analysis, and synthesis have been detected. On the other hand, students can understand that high-tech science and technology are not Castle in the air, magical extraordinary. The following analysis of the college entrance examination questions in recent years to talk about this issue. First, the spacecraft operation problem Example 1 (2001 Guangdong, Henan volume) unmanned spacecraft “Shenzhou II” had been raised from the ground to H =3.4×105m circle
