物理必修一第三章知识点总结

第三章相互作用专题一:力的概念、重力和弹力 1．力的本质 (1)力的物质性：力是物体对物体的作用。提到力必然涉及到两个物体:施力物体和受力物体，力不能离开物体而独立存在,(不离开不是一定要接触)有力时物体不一定接触。 (2)力的相互性：力是成对出现的，作用力和反作用力同时存在。作用力和反作用力总是等大、反向、共线，分别作用在两个物体上，作用效果不能抵消. (3)力的矢量性：力有大小、方向，对于同一直线上力的矢量运算，同向相加，反向相减。 (4)力作用的独立性：几个力作用在同一物体上，每个力对物体的作用效果均不会因其它力的存在而受到影响。 2．力的作用效果 $ 力对物体作用有两种效果：一是使物体发生形变，二是改变物体的运动状态。这两种效果可各自独立产生，可同时产生。 3．力的三要素：大小、方向、作用点完整表述一个力时，三要素缺一不可。当力 F1、F2的大小、方向均相同时，我们说F1=F2。力的大小可用弹簧秤测量，也可通过定理、定律计算，力的单位是牛顿，符号是N。 4．力的图示和力的示意图力的图示：用一条有向线段表示力的方法叫力的图示，用带有标度的线段长短表示大小，用箭头指向表示方向，作用点用线段的起点表示。 5.重力（1）．重力的产生： - 重力是由于地球的吸收而产生的,重力的施力物体是地球。（2）．重力的大小： ○由G=mg计算，g为重力加速度，通常g取米／秒方。 ○由弹簧秤测量：物体静止时弹簧秤的示数为重力大小。（3）．重力的方向：重力的方向总是竖直向下的，不一定指向地心。（4）．重力的作用点——重心 ○物体的各部分都受重力作用，效果上,认为各部分受到的重力作用都集中于一点，叫做物体的重心。(假设的点) $ ○重心跟物体的质量分布、物体的形状有关，重心不一定在物体上。质量分布均匀、形状规则的物体其重心在物体的几何中心上。（5）．重力和万有引力重力是地球对物体万有引力的一个分力，万有引力的另一个分力提供物体随地球自转的向心力，同一物体在地球上不同纬度处的向心力大小不同，但由此引起的重力变化不大，一般情况可近似认为重力等于万有引力，即：mg=GMm/R2。除两极和赤道外，重力的方向并不指向地心。重力的大小及方向与物体的运动状态无关，在加速运动的系统中，例如：发生超重和失
