在高中阶段,同学们会经历大大小小许多考试。在这些考试中,物理试题不仅与高中新课程内容相衔接,而且进一步贴近时代、贴近社会、贴近考生实际,注重对考生运用所学知识分析问题、解决问题能力的考查。一、能力考查型例1匀强电场的方向沿x轴正向,电场强度E随x的分布如图1所示,图中E_0和d均为已知量。将带正电的质点A在O点由静止释放。A离开电场足够远后,再将另一带正电的
In high school, students will experience many tests, large and small. In these examinations, the physics test questions are not only connected with the content of the new high school curriculum, but also close to the times, close to the society, close to the actual candidates, and pay attention to examinee’s ability to use the knowledge to analyze problems and solve problems. First, the ability to examine type 1 direction of the uniform electric field along the positive x-axis, the distribution of electric field strength E with x shown in Figure 1, E_0 and d in the figure are known. The positively charged particle A is released from standstill at point O. A far enough away from the electric field, then another positive
