试题点评:2012年卓越联盟自主招生物理试题覆盖了高中物理必修1、必修2、选修3—1、选修3—2、选修3—3、选修3—4、选修3—5七个模块,难度与高考相当。一、选择题1.我国于2011年发射的“天宫一号”目标飞行器与“神舟八号”飞船顺利实现了对接。在对接过程中,“天宫一号”与“神舟八号”的相对速度非常小,可以认为具有相同速率。它们的运动可以看作绕地球的匀速圆周运动,设“神舟八号”的质量为m,对接处距离地球中心为r,地球的半径为R,地球表面处的重力加速度为g,不考虑地球自转的影响,“神舟八
Test Questions Comments: 2012 Excellent League Independent Enrollment Physics Test Covers High School Physics Required 1, Required 2, Optional 3-1, Elective 2-3, Elective 3-4, Elective 3-4, Elective 3-5 Seven Modules, Difficulty It is equivalent to the college entrance examination. First, multiple-choice questions 1. China’s ”Tiangong-1“ target aircraft launched in 2011 and the ”Shenzhou No. 8“ spacecraft successfully achieved docking. In the docking process, the relative speeds of Tiangong No. 1 and Shenzhou No. 8 are very small and can be considered to have the same speed. Their movement can be seen as a uniform circular motion around the earth. The mass of the ”Shenzhou No. 8“ is m, the distance from the dock to the center of the earth is r, the radius of the earth is R, and the gravitational acceleration at the surface of the earth is g, not Considering the effect of Earth’s rotation,” Shenzhou Eight
