高一物理必修一知识点总结：受力分析
1、受力分析：
根据力的概念，从物体所处的环境(有多少物体接触，在什么场中)和运动状态来看，一般如下。
(1)确定研究对象，并隔离出来;
(2)先画重力,然后弹力 摩擦力,再画电 磁场力。
(3)检查受力图,找出所画力的施力物体,分析结果能否使物体处于题设的运动状态(静止或加速),否则必然是多力或漏力。
(4)合力或分力不能重复列为物体所受的力.。
2、整体法和隔离体法
(1)整体法:就是把几个物体视为一个整体,受力分析时,只分析这一整体之外的物体对整体的作用力,不考虑整体内部之间的相互作用力。
(2)隔离法:就是把要分析的物体从相关的物体系中假想地隔离出来,只分析该物体以外的物体对该物体的作用力,不考虑物体对其它物体的作用力。
(3)方法选择
当所涉及的物理问题是整体和外部效应时，应用整体分析方法可以使问题简单明了，不考虑内力的作用;当所涉及的物理问题是物体之间的相互作用时，采用隔离分析方法，将原来整体的内力转化为单个物体的外力。
3、注意事项：
正确分析物体的受力是解决力学问题的基础和关键，在具体操作中应注意。
(1)弹力和摩擦力都是产生于相互接触的两个物体之间,因此要从接触点处判断弹力和摩擦力是否存在,如果存在,则根据弹力和摩擦力的方向,画好这两个力.。
(2)画受力图时要逐一检查各个力,找不到施力物体的力一定是无中生有的.同时应只画物体的受力,不能把对象对其它物体的施力也画进去.。
易错现象：
1.不能正确判断力和力的存在或不存在。
2.研究课题的选择没有灵活性。
3.在力分析中，力与力不能区分。
