在进入高三复习时,从哪儿开始入手复习,复习些什么,依据什么?笔者认为,通过研究高考题总体可以看出:现在的高考趋势是以生活中的实例和高科技为背景,用物理知识解决其中的问题。复习万有引力定律时可以发现在高考题中有一个连续五年都出现的知识点:卫星或飞船在绕地球运行时,给出地球半径R0,地球表面的重力加速度g,在地球表面重力近似等于万有
When entering the third year review, from where to start review, what to review, based on what? The author believes that through the overall examination of college entrance examination questions can be seen: the current college entrance examination trend is based on life examples and high-tech background, with physical knowledge Solve the problem.
