静力学研究力及物体的受力平衡.本文以《考试说明》中的考点为依据,从提高能力出发,点击静力学的高考热点,对知识和方法做一番整合梳理.力是贯穿于力学乃至整个物理学的重要概念.对物体进行受力分析是解决力学问题的基础和关键.力的合成与分解所遵循的平行四边形定则,也是所有矢量合成与分解所遵循的定则.力学中三种常见的力——重力、弹力和摩擦力,尤其是摩擦力,是 Static research force and object balance of force.This article is based on the “test description” in the test sites, starting from the ability to improve, click on the statics entrance exam hotspots, knowledge and methods to do some integration combing force is through mechanics And even the whole concept of physics.Analysis of forces on the object is the basis and key to solve the problem of mechanics.The principle of parallelogram followed by force synthesis and decomposition is also the rule that all vector synthesis and decomposition follow. Three common forces - gravity, elasticity and friction, especially friction, are
