“重点知识重点考、主干知识年年考”是高考命题的基本规律.为了提高复习效能,本文归纳了历年高考物理的高频考点,以帮助同学们抓住命题脉搏,进行有效的冲刺复习.一、重力、弹力和摩擦力本考点属于物体的平衡和牛顿运动定律的知识范畴,在2012年高考中11次出现对该考点的考查.2013年备考建议要点提示:要牢记重力、弹力和摩擦力的特点;掌握受力分析、整体法和隔离法、力的合成与分解、正交分解法;熟练运用牛顿第二定律.
In order to improve the efficiency of reviewing, this article summarizes the college entrance examination physical high frequency test centers to help students grasp the proposition pulse, the effective sprint Review 1. Gravity, Elasticity and Friction This test site belongs to the knowledge category of object balance and Newton’s law of motion, and the examination of the test site occurs 11 times during the college entrance examination in 2012. Notes for 2013 Remarks: Keep in mind that gravity, elasticity And friction characteristics; master the force analysis, the whole law and isolation law, the synthesis and decomposition of force, orthogonal decomposition method; skilled use of Newton’s second law.
