2013年江苏高考卷第7题是以斜抛运动为知识情境的问题,无独有偶在随后的2013年第30届全国中学生物理竞赛预赛试题中再次斜抛运动情境的问题。高考题与竞赛题之间千丝万缕的联系,值得我们进行探究,下面以今年的两道斜抛题为例进行说明。一、相同的物理情境1.[2013年江苏高考物理卷第7题]如图所示,从地面上同一位置抛出两小球A、B,分别落在地面上的M、N点,两球运动的最大高度相同。空气阻力不计,则
In 2013, Jiangsu Questionnaire Volume 7 was based on the situation of inclined throwing and throwing exercise as the knowledge situation. It was not coincidental that I again inclined to throw the sports situation in the subsequent 30th National Senior High School Physics Contest 2013 Test Questions. College entrance exam questions and the inextricably linked ties, it is worth us to explore, the following two oblique cast this year as an example to illustrate. First, the same physical situation 1. [2013 Jiangsu Physical Examination Volume 7] As shown, the same position thrown from the ground two small balls A, B, respectively, fell on the ground M, N points, two The maximum height of the ball movement the same. Air resistance does not count, then
